    I am using a custom bar renderer to set the bar colour based on the value

    protected override void RenderPointCore(Canvas canvas, DataPoint point)

    However there doesnt seem to be a "Value" attribute ie point.Value.

    I have created a bodge woraround comparing bar height with canvas height

    Am i missing something?

    Hi Paul,

    Thanks for writing.
    You are on the right track. All you have to do is cast DataPoint to CategoricalDataPoint. DataPoint is the base class for our data points. CategoricalDataPoint has getValue() and getCategory() methods.
    Please write again if you need further assistance.

    Regards,
