Hide AllThe Chart control supports the creation of additional custom axes through the use of the chart's CustomAxes collection. Once a custom axis has been added to the collection, in addition to setting the normal axis properties, you will need to set the following properties:
- Parent - The Parent property allows you to choose the primary or secondary axis on which your custom axis resides.
- PlacementLength - The PlacementLength property allows you to set the length of the custom axis in proportion to the Min and Max property values you have already set for the parent axis.
- PlacementLocation - The PlacementLocation property allows you to set the starting location value for the custom axis to appear in relation to the parent axis.

The following code sample demonstrates creating a custom axis, adding it to the Axes collection for the ChartArea, and setting its properties.
