I have a linechart that has two lines (denoting lowest and highest value for each category) rendered with shapes. I want to draw a simple line showing the low/high range for each common domain value, i.e. connecting each low value with its corresponding high value.
I know I could use the HighLowRenderer (possibly overlaid with a line chart to have shapes at the high/low values), but I have a CategoryDataset not a XYDataset.
I guess I would have to write my own renderer. But maybe I am just overlooking a simpler solution ?
