Topic: Marks inside of stacked bars?

Hi. Pascal. Not automatically. But you can do several things: 1) Add extra line (summary) to existing mark text. This can be done in TChartSeries.OnGetMarkText event. 2) Manually draw required texts above series marks in TChart OnAfterDraw event. Basically, use TChart.Canvas.TextOut method to paint ...

Re: TQRChart - no gridlines when printing

It's possible, but it's also possible the problem is in core Delphi metafile routine and it shows up in Quick Report.

Hi.

Do you get these results only with TQRChart or do you get it also if you try to export TChart image to metafile format ? Also, which TeeChart version are you using ? Which Delphi version ?

Do you have any code examples for this? Yes, sure. Try using the following code: procedure CenterMarks(barSeries: TBarSeries); var i : Integer; yPos,yPos1,yPos2: Integer; xPos: Integer; MarkPos: TSeriesMarkPosition; begin MarkPos := TSeriesMarkPosition.Create; for i := 0 to barSeries.Count - 1 do b...

Thanks for the help! My description was incomplete. When I change the reference from Intraweb_50_60 to Intraweb_60_60, it wants to recompile the Intraweb package, but it can't. Before I test the packages with the latest IW version, try setting the IMPLICITBUILD flag to OFF (select the "Explicitly r...

Hi. You could use one of the cross tab features included in TeeChart (check the demo to see how it works), but I think your solution is also quite good. Well, you could pre-create specific number of series and then display/hide them by setting the TChartSeries.Active property, but freeing and re-add...

Hi, Pascal. One easy workarund for this is to set marks ArrowLength propety to negative (reasonable) value. For example, the following code: Series1.Marks.ArrowLength := -25; will display marks inside bars. Of course, the problem might arise if bars heights are less than 25 pixels, but in other case...

Hi. True, I get the same results even with the latest TeeChart v7 beta sources. I guess SetMinMax was designed as TChartAxis method and should work only with single axis. In your case the workaround is to manually set right axis scale. I'd place the code in the TChart.OnZoom event. Here is pseudo-co...

Hi, Lasse.

This one is relatively simple. All you must do is set the series VertAxis property to aRightAxis:

Series1.VertAxis := aRightAxis;

Then Series1 will use right axis as it's vertical axis.

Hi. Are you having problems only with TChart component in module or apache modules in general ? I must say I haven't tried it myself, but Brian Long wrote a good article about Delphi Apache modules a while ago.
