MindFusion.WebForms Pack, 2015.R1

MindFusion announceс а неш release of our WebForms suite of components. Here is an overview of the most important new features:


We no longer make separate trial build of the control assemblies. Instead there is a new LicenseKey property, which disables a component’s evaluation mode. If your application contains more than one control by MindFusion, you could call MindFusion.Licensing.LicenseManager.AddLicense(key) to specify the key once instead of setting it per each control. License key strings are listed on the Keys & Downloads page at MindFusion’s customer portal.

Zoom control

The ZoomControl class from MindFusion.Common.WebForms lets users change interactively the current zoom level and scroll position of a DiagramView or a MapView. To set it up, add a ZoomControl element to the page and set the control’s TargetId property to the id of the view. The control has numerous properties for customizing its appearance.

Visual Studio 2015 Toolbox Support

MindFusion.WebForms components can now be installed automatically into Visual Studio 2015 toolbox palette.


Custom Formatting of Labels for Line charts

Line charts now support custom formatting of labels. To use custom formatting, set LabelFormat to NumberFormat.Custom and use LabelCustomFormat.

Sorted Bars

The algorithm for sorting of bars has been improved. Bars in a series or in clusters can be sorted in ascending or descending order – use the SortOrder property. You can also sort each series/cluster with the SortSeriesBy property. Bar can be sorted with their colors preserved if SortColor is set to true.

Combination Chart in Android

This post is a step-by-step tutorial in how to create a combination chart in android with the Charting for Android library.

I. Project configuration

Let’s create a new project. In Eclipse, we choose File -> New -> Android Application Project. We write “CombinationChart” as an application name. The package is called com.mindfusion.combinationchart. The other settings remain unchanged.

II. Adding the jar file.

With project created, it’s time to add the libraries. Copy the droidchart.jar from the libs directory of the sample project (download file here) to the libs directory of your project. Then right-click on your project and choose Properties -> Java Build Path -> Libraries -> Add JARs. Navigate to the libs folder and add the droidchart.jar.

Adding a JAR library to an Android application project

Adding a JAR library to an Android application project

III. Declaring the chart

Time to declare the chart in the layout of the application. We build a simple application, where the chart will be the only thing that shows. So, we edit the activity_main.xml file, which is found in res -> layout folder in the project tree for the CombinationChart application.

We change the layout to Linear and we introduce a new xml node – chart. The chart node refers to a class found in the com.mindfusion.charting namespace.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Then we declare the chart:

tools:context=”.MainActivity” />

We name it combi_chart. This is important because we’ll use the name to retrieve the chart object in the next step.

IV. General chart settings.

In this step we’ll set the general chart settings. First, we get the chart object, which is declared in the layour (see previous step).

private AxesChart chart;
chart = (AxesChart)findViewById(R.id.combi_chart);

Then we set the title and the offset of the title e.g. the space between the title and the plot are for the chart. We also set the height of the font for the title labels and the other labels at the chart.

chart.setTitle("Visitors in Paradise Hotels");

V. The grid.

Our chart has a crossed grid with light gray grid stripes. This is set with the following code:

ArrayList gridStrokes = new ArrayList();
gridStrokes.add(Color.rgb(207, 207, 207));


VI. The axes.

The X-axis has 10 intervals. Each division has its own label. We set the label type to custom text, specify the labels and customize the min and max numbers to be shown:


ArrayList xLabels = new ArrayList();
Collections.addAll(xLabels, "2005", "2006", "2007", "2008", "2009", "2010", "2011", "2012", "2013", "2014");

The Y-axis has no custom labels, it just shows the value intervals. But it has a title. Here is how we set it:

chart.yAxisSettings.setTitle("in thousands");

VII. The bar series.

The first series is a bar series. We create a new instance of the BarSeries class and add 10 x and y float numbers, which will be used to calculate the size and location of the bars:

BarSeries series1 = new BarSeries();

ArrayList xData = new ArrayList();
for(int i = 0; i < 10; i++)

ArrayList yData1 = new ArrayList();
Collections.addAll(yData1, 15f, 17f, 18f, 19f, 18.4f, 16.4f, 12f, 17f, 18.7f, 19.1f );

The next thing to do is to specify the colors for the bars and their outlining. The library has the FillColors and StrokeColors property, which we use:

ArrayList fillColors1 = new ArrayList();
fillColors1.add(Color.rgb(174, 200, 68));

ArrayList strokeColors1 = new ArrayList();
strokeColors1.add(Color.rgb(115, 133, 45));

Let’s not forget to add the ready series to the collection of series.


VIII. The line series with scatters.

The line series is an instance of the LineSeries class, where we set the ScatterType and LineType properties:

LineSeries series2 = new LineSeries();

The ScatterFillColors and ScatterStrokeColors are used for setting the colors of the scatters. The properties for the line are the same as with the bar series: StrokeColors.

IX The area series.

The area series has a different line type than the scatter series. We don’t set the scatter type here since its set to “None” by default.

The data in both line series is set in the same way as in the bar series and we don’t cite it again.

LineSeries series3 = new LineSeries();

Here is the final chart:

Scatter Line Chart in WinForms with a Custom Legend

In this post we show you how to build a multi-series scatter chart with a legend and a separator. We use MindFusion.Charting tool for WinForms.

The Data

The properties that specify data in the control are XData and YData. We add three series to each one for the three series that we want to show. Before that, we clear the arrays, to make sure no previously added data shows on the chart:

 lineChart1.XData.Add(new List{3,4,5,6,7,8,9});
 lineChart1.XData.Add(new List{1,2,3,4,5,6,7,8});
 lineChart1.XData.Add(new List{1,2,3,4,5,6,7,8,9,10});

 lineChart1.YData.Add(new List{92, 112, 241, 195, 201, 188, 212});
 lineChart1.YData.Add(new List{512, 480, 321, 491, 460, 320, 298, 241});
 lineChart1.YData.Add(new List { 340, 302, 322, 401, 487, 503, 421, 460, 513, 490 });

Chart Series

We want to show line series with scatters – since this is the default LineType, we don’t have to set anything. In order to customize our series, we add new pens to the ChartPens property. The colors of the scatters are customized with ShapePens and ShapeBrushes. We make the chart pens a bit thicker – 3 pixels.

 lineChart1.ShapeBrushes.Add(new MindFusion.Drawing.SolidBrush(Color.FromArgb(175, 251, 175)));
 lineChart1.ShapeBrushes.Add(new MindFusion.Drawing.SolidBrush(Color.FromArgb(176, 224, 230)));
 lineChart1.ShapeBrushes.Add(new MindFusion.Drawing.SolidBrush(Color.FromArgb(216, 191, 216)));

 lineChart1.ChartPens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(144,238,144), 3.0f));
 lineChart1.ChartPens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(70, 130, 180), 3.0f));
 lineChart1.ChartPens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(186, 85, 211), 3.0f));

 lineChart1.ShapePens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(144, 238, 144)));
 lineChart1.ShapePens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(70, 130, 180)));
 lineChart1.ShapePens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(186, 85, 211)));

Separator Line

We would like to show a separator line that indicates the average value from all chart data. We add a SummaryValue to the SummaryValues collection. Then we customize the summary line by specifying its pen, scatter type and scatter size. We also set the pen and the brush for the scatters. Here is how we do it:

  lineChart1.SummaryPens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(255,69,0), 4.0f);
  lineChart1.SummaryShapeBrushes.Add(new MindFusion.Drawing.SolidBrush(Color.FromArgb(255,228,225))); 
  lineChart1.SummaryShapePens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(255,69,0));

Axes Labels

We want to show custom text at the X-axis, so we set XAxisSettings.LabelType to AxisLabelType.CustomText. We use the XLabels property to add the labels. We also add a title with the XAxisSettings.TitleLabel property.

For the Y-axis we want to show the auto scale – we set it with YAxisSettings.MaxValue, YAxisSettings.MinValue and YAxisSettings.AxisDelta. We show ticks on both axes with the MajorTickLength property.

 lineChart1.YAxisSettings.AxisDelta = 50;
 lineChart1.YAxisSettings.MajorTickLength = 2F;
 lineChart1.YAxisSettings.MaxValue = 600;
 lineChart1.YAxisSettings.MinValue = 0;

 lineChart1.XAxisSettings.AxisDelta = 1;
 lineChart1.XAxisSettings.LabelType = MindFusion.Charting.AxisLabelType.CustomText;
 lineChart1.XAxisSettings.MajorTickLength = 5F;
 lineChart1.XAxisSettings.MaxValue = 11;
 lineChart1.XAxisSettings.MinValue = 0;
 lineChart1.XAxisSettings.TitleLabel = "Year";

The Legend

The labels for the legend are set with the LegendLabels property. The colors are picked automatically from the ChartPens property for each series. We place the legend at the bottom with LegendPosition and increase its offset with LegendOffset. We want the legend in one row, so we set LegendColumns to the count of the labels – 3.

 lineChart1.LegendColumns = 3;
 lineChart1.LegendLabels = new List{"Europe, Asia, North America"};
 lineChart1.LegendOffset = 30f;
 lineChart1.LegendPosition = MindFusion.Charting.Position.Bottom;

Line Chart with a Separator in WinForms

In today’s post we’ll show how to build a line chart with several line series and a separator line. The separator line is drawn at a given height and divides the chart into two halves.

The Line Series

The line series are three, so we must add three lists with data to the XData and YData properties. We can do this in three ways: type the values in design time, write them in code or use data binding. In design time we use the built-in collection editors of the control:

The Series collection editor

The Series collection editor

In code we make lists with the data and add them to XData or YData:

lineChart1.YData.Add(new List { 45, 64, 38.2, 33.03, 56, 68, 39, 42 });
lineChart1.YData.Add(new List { 34, 42, 28, 42, 35, 31, 62, 55 });
lineChart1.YData.Add(new List { 22, 19, 32, 28, 17, 25, 31, 36 });

If you want to use data binding then set DataSource to the name of the data source, DataMember to specify the name of the table which will supply the data and XDataFields/YDataFields to provide the name(s) of the fields. In this case we will require three data base columns for each of the three series – separate the names with a comma e.g.

lineChart1.YDataFields = "Sales1,Sales2,Sales3";

For XData we use the same list because we want the series to appear exactly under each other:

lineChart1.XData.Add(new List { 10, 20, 30, 40, 50, 60, 70, 80 });
lineChart1.XData.Add(new List { 10, 20, 30, 40, 50, 60, 70, 80 });
lineChart1.XData.Add(new List { 10, 20, 30, 40, 50, 60, 70, 80 });

The Series

We set LineType to Line and Scatter because we want to show scatters at data points:

lineChart1.LineType = MindFusion.Charting.LineTypes.Line |  

The LineTypes enumeration allows bit wise combining of its members. We use ChartPens to set the pens for the line series. ShapesPens and ShapeBrushes set the pens for the outline and the brushes for filling the scatters:

lineChart1.ChartPens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(102, 205, 170), 6));
lineChart1.ShapePens.Add(new MindFusion.Drawing.Pen(Color.FromArgb(102, 205, 170), 2));   

The pens for the series are thicker than the pens for the scatters. The fill brush is slightly lighter:

lineChart1.ShapeBrushes.Add(new MindFusion.Drawing.SolidBrush(Color.FromArgb(175, 251, 175)));

Finally – we set the size of the shapes and their type:


The Separator

There are two ways to draw the separator line.

The first is to add a custom summary value. In this case the separator line will be drawn from the
smallest X-data value to the biggest one, parallel to the axes.

lineChart1.AddCustomSummary(40.0, "");

The summary line is drawn with shapes at both ends, but we can hide them by setting their size to 0:

lineChart1.SummaryBrushes.Add(new MindFusion.Drawing.SolidBrush(Color.Gray));

The second way to draw the separator line is to add it as a 4th series in the XData and YData lists and add a pen for it in the ChartPens list. The advantage is that we can make the line as long as we want, in our case – as long as the length of the X-axis:

lineChart1.XData.Add(new List { 0, 90 });

The Legend

We use LegendLabels to add the labels for the line series:

lineChart1.LegendLabels = new List() { "2010", "2011", "2012" };

We set the background of the legend, but we don’t have to add any brushes or shapes for the legend items – they are taken automatically from the line series settings:

lineChart1.LegendBackgroundBrush = new MindFusion.Drawing.SolidBrush(Color.FromArgb(253, 253,  

The Grid

The GridType is GridType.HorScale. We use GridBrush, AltGridBrush and GridPen to set the colors for the grid.

lineChart1.GridPen = new MindFusion.Drawing.Pen(Color.FromArgb(200, 200, 200));
lineChart1.GridPen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dash;
lineChart1.GridType = MindFusion.Charting.GridType.HorScale;

If you make the changes to the chart in code, don’t forget to call UpdateChart() to make sure the
control knows changes have happened and the chart must be updated.

Here is the final chart:

Line Chart with DateTime Data in ASP.NET

In this post we demonstrate how to use MindFusion.Charting for ASP.NET component to create a line chart that shows the number of unique visitors to a store/website in a period of 6 weeks.


The data for the X-axis are DateTime values. We create an array with the DateTime values that we’ll use and add it to the XData property of our chart. Before that we have to delete the predefined array that is added when the control is dropped at the form:

DateTime dt1 = new DateTime(2013, 6, 14);
DateTime dt2 = new DateTime(2013, 6, 7);
DateTime dt3 = new DateTime(2013, 5, 31);
DateTime dt4 = new DateTime(2013, 5, 24);
DateTime dt5 = new DateTime(2013, 5, 17);
DateTime dt6 = new DateTime(2013, 5, 10);

ArrayList data = new ArrayList() { dt1, dt2, dt3, dt4, dt5, dt6 };

Next, we must make some adjustments in the settings for the X-axis to tell the control that DateTime data is used. We set the DataFormat property to DateTime and we specify the time range for the axis. This is how we do this:

LineChart1.XAxisSettings.DataFormat = MindFusion.Charting.DataFormat.DateTime;

LineChart1.XAxisSettings.StartDateTime = new DateTime(2013, 5, 3);
LineChart1.XAxisSettings.EndDateTime = new DateTime(2013, 6, 20);
//set the interval to one week - 7 days
LineChart1.XAxisSettings.TimeSpan = new TimeSpan(7, 0, 0, 0);

The data for the Y-axis are numbers. We can set them through the property grid or set them in code.

ArrayList data1 = new ArrayList() { 56, 13, 45, 17, 82, 22 };

The X-axis

First, we must change the LabelType property of XAxisSettings from “ChartData”, which is the default to “AutoScale”. This will make the axis show the time range we’ve set in code above. Then, we change how the DateTime values will be formatted. The Default DateTimeFormat shows the full time and date and is not suitable. We change it to “LongDate”, which does not draw any time.

XAxisSettings-DrawTicksUniformly="False" XAxisSettings-DrawZero="True" 
XAxisSettings-LabelBrush="s:#FF696969" XAxisSettings-LabelOffset="10" 
XAxisSettings-LabelType="AutoScale" XAxisSettings-TitleLabel="Week" 
XAxisSettings-TitleLabelBrush="s:#FF696969" XAxisSettings-TitleLabelOffset="10"

We type “Week” as TitleLabel for the axis and set the DrawZero property to true to show the first label, which is otherwise omitted.

Upon preview we notice that the labels are too close to the axis, that’s why we use LabelOffset and TitleLabelOffset to add some space before them. Finally, we change the color of the labels, to make them dark gray rather than black.

The Y-axis

Customizing the Y-axis is rather simple. We change the interval with AxisDelta to 5 and increase the MaxValue to 100. We don’t need decimal fractions for the labels, that’s why we change the NumberFormat. We add a TitleLabel and change its orientation with TitleLabelOrientation. Finally we use LabelBrush and TitleLabelBrush to change the colors of the labels – we use the same brushes as for the X-axis.

YAxisSettings-MaxValue="100" YAxisSettings-NumberFormat="Fixed_point_0Digits" 
YAxisSettings-TitleLabel="Unique Visitors" 

The Grid

Initially the chart shows no grid – but we want to show a grid. That’s why we change GridType to “Crossed” and set a GridPen. The dark gray background of the plot area together with its outlining are set with PlotAreaOutlinePen and PlotAreaBrush.

GridPen="n:0/#FFE1E1E1/0/0/0//0/0/10/" GridType="Crossed" PlotAreaBrush="s:#FFC0C0C0" 

This is the code that was generated by the designer because we set the properties through the property grid. If we set them with code, it will be:

LineChart1.GridPen = new MindFusion.Drawing.Pen(Color.FromArgb(225,225,225));
LineChart1.GridType = MindFusion.Charting.GridType.Crossed;
LineChart1.PlotAreaBrush = new MindFusion.Drawing.SolidBrush(Color.FromArgb(192, 192, 192));
LineChart1.PlotAreaOutlinePen = new MindFusion.Drawing.Pen(Color.FromArgb(120, 120, 120));

The Line Series

We want scatters at data points and we want to show labels above those scatters. The LabelType property lets us set the type to be both line and scatters:

LineChart1.LineType = MindFusion.Charting.LineTypes.Line | MindFusion.Charting.LineTypes.Scatter;

This is the default type, so you don’t need to set it if you have not changed it before. We use ShapeBrushes, ShapePens and ShapeSizes to set the brushes and size of the scatters. We can do this in the property grid or in code. Finally, we want to show labels above scatters. We use LabelType and LabelFormat to set what kind of labels are drawn and since our labels are numbers – how they are formatted.

LabelBorder="RoundedRect" LabelBorderBackground="s:#FFFFFFE0" LabelBorderOutline="n:0/#FF787878/0/0/0//0/0/10/" LabelFormat="Fixed_point_0Digits" LabelType="Data"

In code you write:

LineChart1.LabelBorder = MindFusion.Charting.Border.RoundedRect;
LineChart1.LabelBorderBackground = new MindFusion.Drawing.SolidBrush(Color.FromArgb(255, 255, 224));
LineChart1.LabelBorderOutline = new MindFusion.Drawing.Pen(Color.FromArgb(120, 120,120));
LineChart1.LabelFormat = MindFusion.Charting.NumberFormat.Fixed_point_0Digits;
LineChart1.LabelType = MindFusion.Charting.LabelType.Data;
