XAxisLabelRotation property

Use the XAxisLabelRotation property to specify the angle of rotation value (in degrees) that should be applied to x-axis labels. This is a design-time and a run-time property. However, changing the value will not update the chart until the next time the chart is refreshed or the DisplayChart() method is called.

Valid values behave as follows:

• Null results in the label being at 0° (horizontal text with a direction from left to right) unless the labels will overlap, in which case the appropriate angle will be calculated automatically.

• 0 results in fixed horizontal text. Labels will not be rotated if they overlap.

• Positive values rotate the labels counterclockwise. For example, 90 results in vertical text turned 90° counterclockwise (text direction is bottom to top).

• Negative values rotate the labels clockwise. For example, ‑90 results in vertical text turned 90° clockwise (text direction is top to bottom).

The following figure shows the label rotated using a value of 45 (that is, 45° counterclockwise).
