To solve this problem, I would need a function like TTreeNode.MakeVisible() which doesn't exist in TeeTree (as TTreeNodeShape don't inherit from TTreeNode).
Still no support about this problem ?

Panning with Log Axes can bring negative values
Hello, If you have an axis with Logarithmic = true and the panning tool activated, you can scroll the chart until the logarithmic axis has negative min and max. The negative values are not displayed, but this causes some strange behaviour with the labels. I guess a test should be made in class TChar...

[Solved] Force position of vertical scrollbar ?
Hello,
Is it possible to force the position of the vertical scrollbar ? Sometimes i must build again all my treeview, and i would like to show the treeview at the same position as before it has been rebuilt.

Why you don't use
?
I think creating a TChartAxis creates a vertical axis, and then you cannot assign it as a horizontal axis.
Code: Select all
ca := THorizAxis.Create(Chart1);

Hi Pep, Thanks for the answer but your solution doesn't work. I'm using the filter right before creating the Metafile, and then I'm using it to print, but the chart is still not in grayscale. TeeGrayScale((Chart.Canvas as TTeeCanvas3D).Bitamp, true, 0) ; MetaChart := Chart.TeeCreateMetaFile(True, Ch...

Hi Narcis, Ok but my problem is that Monochrome is different than Grayscale : chart.monochrome looks different than teeGrayscale(), and moreover i'm also using the reverted grayscale (white becomes black, etc.). Seeing your answer, I should understand that you did not yet implement the printing in t...

Print in Grayscale
Hello,
I'm using the feature TeeGrayScale() in the afterDraw method, but I can't use it also to pring the chart in grayscale. Is it possible ? Thanks

[Solved] [v8] Bug with TAxisScrollTool
Hello, I found a problem with the TAxisScrollTool which I think occurs only with Version 8. When I'm scrolling an Axis using this tool, everything works fine except when the cursor is exactly over the axis line ! This behaviour looks strange and I think it is a bug. To reproduce it, simply scroll th...

I don't know if it's the best answer, but you can try this : value : real ; i, index : integer ; value := Chart.BottomAxis.CalcPosPoint(X) ; //find the value of the clicked point for i := 0 to Series.count-1 do if Series.XValues[i] >= value then begin index := i ; //find the index in the series brea...
