Regardless of which automatic axis layout type you use, the Chart Control allows you to apply manual offsets. Specify the offset property in pixels to keep the axis position unchanged when users scroll or zoom the Chart data. The offset property shifts the axis from the specified position as follows:
-
If the axis is horizontal, a negative offset shifts the axis to the top, a positive offset shifts it to the bottom.
-
If the axis is vertical, a negative offset shifts the axis to the left, a positive offset shifts it to the right.
In this demo, you can use controls under the Chart to change the customPosition and offset properties for both axes.
