Narcis, Pointing to the source code it looked obvious to me that this was happening, but seeing is believeing: --Paul procedure TForm1.FormCreate(Sender: TObject); var LS: TLineSeries; begin Chart1.View3D := false; LS := TLineSeries.Create(Chart1); LS.Pen.Width := 2; LS.FillSampleValues(6); Chart1.A...

I have used Madshi's madExcept with good results for these types of exotic problems. You need to buy a license to deploy the exception tracking, but for your own debugging I think the eval will work.

TFactsTheme observation

When I apply TFactsTheme I notice that line charts disappear. Looking at the code for Apply, I see that this is happening but wonder why this is done. Is this a bug or is this done for a reason I do not understand?? --Paul for t:=0 to SeriesCount-1 do with Series[t] do begin Pen.Visible:=False;

Stacked bars draw incorrectly in 3D

When I generate a chart with the code below, the 3D view is not correct. Note how on X=1, series2 is next to series 1, but seems to be behind series4. --Paul procedure TForm1.FormCreate(Sender: TObject); var B: integer; Bars: array[1..4] of TBarSeries; begin for B := 1 to 4 do begin Bars[B] := TBarS...

Using stacked area series with a transparent series

When I use the code below, I have two problems: 1. The right hand side of the transparent series is not transparent (it shows in 3D) 2. When I save the chart as an EMF file, the first series is no longer transparent; it is visible. PNG format and BMP format save the image as shown. I'm not sure if m...

Narcis,

In the non- GL version, rotate the graph around (play with the view) and
I think you will see that the surface goes too 'high' (too deep from a 3D
point of view). It does not go through the wall as it does in the GL version.

Clipping problem with 3D surface

When I set the minimum value for the bottom axis to a higher value, the left wall does not clip the chart. To demonstrate, my form contains a commander bar and a chart edior. After the chart is shown, change the view such that you see the left wall clearly and press the button on the form to change ...

Title ignored when using a custom axis (bug?)

I created a custom axis, with Horizontal = true, OtherSide=true, Position=0 so it sits on top of my chart and the text higher. When I select the series horizontal axis to be the top axis, the chart gets smaller so the title area is not obstructed. When I select my custom axis, the chart get larger a...
