Hi,

There is a way to speed up the GridLayout elaboration?
Currently I use these commands:

procedure GridLayoutArrange;
var gl: GridLayout;
begin
     gl := CoGridLayout.Create();
     gl.GridSize := 80;
     gl.ArrowAnchoring := ancReassign;
     screen.Cursor := crHourGlass;
     flowChartMain.ArrangeDiagram(gl);
     flowChartMain.ZoomToFit;
     flowChartMain.FitDocToObjects(10);
     screen.Cursor := crDefault;
end; 

I checked the numiteration property, what can be the best number to have a good result? Or there is a better way to speed up? (Often nodes >500 and arrows>1000)

This can be a good deal while we wait for the new "progress" method.

Thank you.

I show you a real case:



this is a chart drawn taking data from a database and arranged via GridLayout method. It took nearly 5 minutes with default options (probably less with NumIterations := 500).

The problem is that those charts could be significant larger (up to 3000 nodes and 3000 arrows).

Is there a method to implement a similar layout with less time cost?

Also it would be great if GridSize could be divided into "horizontal" and "vertical" so we can differentiate the spacing and draw different type of nodes (ex. rectangles instead of squares).

Any hints?

okay, let me do a prototype without "sensitive" informations and I'll send you via email.

Is it okay if I export it with SaveToFile Method?

thank you very much.

great! there was a significant improvement. For the perfection we wait for the "end of rearrangement" event.

Thank you very much for your support. More questions are coming
