Hi Jorge,
Whilst making a demo application to send to you, I accidentally found a solution. If you set the SeriesDefaults.Renderer := jqprBarRenderer at design time and then dynamically add 2 new series at run time (mySeries1.Renderer := jqprLineRenderer and mySeries2.Renderer := jqprBarRenderer), the chart will show only bars
However, if you set the SeriesDefaults.Renderer := jqprLineRenderer at design time and then dynamically add 2 new series at run time (mySeries1.Renderer := jqprLineRenderer and mySeries2.Renderer := jqprBarRenderer), the chart will show both the bars and lines
I guess this is a feature of JQPlot and not the fault of IWCGJQPlot.
While I'm here, could I ask a related question. When I change the IWCGJQPlot SeriesDefaults.Renderer at design time, the RendererOptions change depending on the type of Renderer chosen. How can I change the variables in the RendererOptions at run time for both line and bar types? Is there an object that provides access to the relevant variables?
Thanks again for all your help.
Richard
