Change Individual Bar Colour If Higher Than Same Category In Another Series

[IT]

Hi,

I have 2 series of data as shown in the picture. The green bar is the target time to complete a task and the blue bar is actual time taken. I need to make the blue bars turn red if they are higher than the green bars? Can this be done?

Thanks

Hi Shane,

Thank you for writing.

You can iterate the elements after the series are added to the chart:

foreach (BarPointElement item in barSeries.Children)
{
    var point1 = ((CategoricalDataPoint)item.DataPoint);

    foreach (CategoricalDataPoint point in barSeries2.DataPoints)
    {
        if (point1.Category == point.Category)
        {
            if (point1.Value > point.Value)
            {
                item.BackColor = Color.Red;
                break;
            }
        }
    }
}

Let me know if you have additional questions.
