DBChartTools

rbuser

I have a DBChart on a Report. I added two Chart Tools to the DBChart but I
need to set the values ar run time. I can't seem to find my way to the
Chart tools in design mode to make the assignments.


RB 7.04 Ent
TeeChartPro 6.01

Hi Larry,

You can use the TppDPTeeChart.Chart property to access the actual
TCustomChart object being used. I believe then you have access to the Tools
property which gives you access to any chart tools you have created. See
the TeeChart help for more information.

I spent half the night trying what you say. It would almost seem as if the
properties we not published.
Finally I surrendered and rolled my own along the lines of:

Does anyone else make charts that work with your reports. We are getting
ready to upgrade RB but I am not impressed with the Steema products.


CenterLineTool:= TColorLineTool.Create(ppDPTeeChart1);
ColorBandTool:= TColorBandTool.Create(ppDPTeeChart1);
With CenterLineTool Do
Begin
AllowDrag := false;
Draw3D := False;
Pen.Style := psDot;
Pen.Width := 3;
Value := FieldByName('MeanWt').AsFloat;
Axis := ppDPTeeChart1.Chart.BottomAxis;
End;

With ColorBandTool do
Begin
Brush.Color := 12728525;
Color := 4227327;
EndValue := FieldByName('HiLimit').AsFloat;
Gradient.Balance := 71;
Gradient.EndColor := 8454143;
Gradient.MidColor := clTeal;
Gradient.StartColor := 8388863;
StartValue := FieldByName('LowLimit').AsFloat;
Axis := ppDPTeeChart1.Chart.BottomAxis;
End;


ppDPTeeChart1.Chart.Tools.Add(CenterLineTool);
ppDPTeeChart1.Chart.Tools.Add(ColorBandTool);

Hi Larry,

We do not know of any other charting products that work with ReportBuilder
however if you do find a product that you like and it produces a chart image
in Delphi, it is rather easy to transfer that image to a ReportBuilder
report to display the chart. Many of our customers already do this with
TeeChart.
