Primefaces (Line)ChartModel define Linecolor

[JayJay]

Hello,


I will combine a "SelectManyCheckbox" with a LineCharModel.
If a checkbox is activated, a line will be shown in the chart. Thats no problem!

But the linecolor depends on the order of my series.


question/example: is it possible, so set seriesX in the bean always to blue and seriesY always to red?

First check if you can set the color n the model. If that is not possible, Check how to do that in jQPlot (what PF charts is based upon). Then use the extender function to set it like jqplot wants it.

ChartModel provides method: public void setSeriesColors(String seriesColors),
You can set the seriesColors dynamically base on the checked items.
just like:

Code: Select all

Map<String,String> colors = new HashMap<String,String>();
colors.put("seriesX", "00008B");
colors.put("seriesY", "8A2BE2");
colors.put(....

String seriesColors = "";
for(String item : checkedItems){
	seriesColors+=colors.get(item)+",";
}
...
chartDataModel.setSeriesColors(seriesColors)
