Help needed in rad chart

[Akki]

Hi all,

I have two issues in rad chart.

1. How to inclined the x-axis values i.e. rotate the x-axis series in 45 or 270 degree to clear view the x-axis in rad chart.
2. How to remove or giving null value to the values which is zero in chart area.



Thanks in Advance.

Hi Akki,

You can control rotation of the axis labels using the LabelAppearance.RotationAngle property of your axis like this:

RadChart1.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 45;

Regarding your other question, in order to show dates to an axis, values should be converted to OleAutomation types. It can be accomplished by using the DateTime.ToOADate() method.

As for removing zeroes from your series items, attach to the chart's  ItemDataBound event like this:

void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)
    {
        if (e.SeriesItem.YValue == 0)
        {
            e.SeriesItem.Label.TextBlock.Text = " ";
        }
    }

I have also attached  a sample project that you could refer to for more information.
