I need to use a JQPlot to present 3 values in a bar graph. I would like each bar to have its own color, and show a text label on the x-axis. SO far I can only get the basic graph showing. I cannot figure out how to get the x-axis labels. Should I be using a single series?

I am working backwards from the examples in the demo.

Code: Select all

IWCGJQPlot1.JQPlotData:= '[[200],[600],[700]]';
IWCGJQPlot1.JQPlotOptions.SeriesDefaults.Renderer:= jqprBarRenderer;
IWCGJQPlot1.JQPlotOptions.SeriesDefaults.BarRendererOptions.FillToZero:= True;
IWCGJQPlot1.JQPlotOptions.SeriesDefaults.PointLabels.Show:= True;
IWCGJQPlot1.JQPlotOptions.Legend.Show:= false;

Axis:= IWCGJQPlot1.JQPlotOptions.Axes.Add;
Axis.Options.AxesRender:= jqparCategoryAxisRenderer;

Axis:= IWCGJQPlot1.JQPlotOptions.Axes.Add;
Axis.AxisType:= jqpoxyYAxis;
Axis.Options.Pad:= 1.05;
Axis.Options.TickAxisOptions.FormatString:= '%d';


Hello

The jqplot expert only will be here on Monday.

Can you find an example of what you want in our demo or in here?

Hi dfields,

Do you need something like this?



Best Regards.

Yes. I was also trying to have each bar be a different color. I have been able to accomplish that by using 3 series, each with a single value.

How do you add the x-axis value labels?

Hi dfields,

Here you have the code:

delphi code

procedure TIWForm3.IWAppFormCreate(Sender: TObject);
var
  Axis: TIWCGJQPlotOptionsAxesItem;
begin
  IWCGJQPlot1.JQPlotData:= '[[["Test1",200],["Test2",600],["Test3",700]]]';
  IWCGJQPlot1.JQPlotOptions.SeriesDefaults.Renderer:= jqprBarRenderer;
  IWCGJQPlot1.JQPlotOptions.SeriesDefaults.BarRendererOptions.VaryBarColor:= True;
  IWCGJQPlot1.JQPlotOptions.AxesDefaults.TickRenderer:= jqptrCanvasAxisTickRenderer;
  IWCGJQPlot1.JQPlotOptions.AxesDefaults.TickCanvasAxisOptions.Angle:= -30;
  Axis:= IWCGJQPlot1.JQPlotOptions.Axes.Add;
  Axis.AxisType:= jqpoxyXAxis;
  Axis.Options.AxesRender:= jqparCategoryAxisRenderer;
end;

Best Regards.
