Hi,

I'm looking at FlowChart.NET for a project that I'm working on. Thus far I'm very impressed.

I'm using the TreeLayout class to arrange my FlowChart that contains some Groups of nodes. The graphs that I want to render might not have dependencies between the nodes in the graphs at certain points of their lives.

When I have nodes in a graph with dependencies between these nodes everything renders perfectly (love all the options and looks). My problem is when a node has no dependencies, thus not having any link, it gets "lost" or rendered over.

For example: I have n01 and n02. I put them in the graph, first n01 then n02. They have no link between them. When I render the image created by the FlowChart instance I only see n02.

These are the FlowChart properties I used:

_flc.AntiAlias = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
_flc.MeasureUnit = GraphicsUnit.Pixel;
_flc.DocExtents = new RectangleF(0, 0, 600, 400);
_flc.BackColor = Color.White;
_flc.SelectAfterCreate = false;
_flc.SelHandleSize = 6;
_flc.BoxStyle = BoxStyle.Rectangle;
_flc.RoundedArrows = true;
_flc.RoundedArrowsRadius = 12;
_flc.ArrowHead = ArrowHead.PointerArrow;
_flc.ArrowHeadSize = 15;

And the TreeLayout properties:

_tl = new TreeLayout();
_tl.Root = _rootNode;
_tl.Type = TreeLayoutType.Centered;
_tl.Direction = TreeLayoutDirection.LeftToRight;
_tl.ArrowStyle = TreeLayoutArrowType.Straight;
_tl.KeepRootPosition = true;
_tl.NodeDistance = 100;
_tl.LevelDistance = 100;

What can would I do so all the boxes get rendered?

hi Stoyo,

Thanks for the quick reply, I will get on this issue today and report on what happened. Thanks again for the great support.

thank you for sharing your findings  8)
