    hi,
    i would like to put a specific color on one and only one bar of my bar chart which contains only one serie.  is it possible? i have found a lot of examples allowing to color a complete serie but this is not what i am trying to do.

    thanks a lot

      You will have to extend the BarRenderer and use that class to modify the color of the bars.

      How do you change the BarRenderrer?
