PEP_structEXTRAAXISTX

Purpose

This property sets and gets an EXTRAAXIS structure describing an extra axis to construct on top of the grid area.

This property is used to manage extra top x axes. These axes are not directly related to data and are purely visual items. If you want to plot data with respect to these extra scales, then the data will need to be normalized with respect to the first top x axis scale. Before calling this method, set WorkingAxis to the axis index (0 through 4) for the appropriate axis if using more than one extra top x axis. Note, this is an alternate use of WorkingAxis which usually corresponds to the use of MultiAxesSubsets. In the case of extra x axes, WorkingAxis is used to designate an extra axis index. In this way, an image can be constructed with up to 5 extra x axes on top and/or on bottom of image.

See example 130 within demo for more information.
