The legendupdate dialog box is used to update or reconstruct legend on the graph page/layer. It is accessible when a graph window is active, by selecting Graph:Legend:Update Legend menu items. This dialog is using the X-Function legendupdate.
The following table provides reference for the controls in this dialog:

This is only available when Update Mode is set to Reconstruct. This is to specify the type of legend you want to reconstruct.
This is only available when Update Mode is set to Reconstruct. This is to specify the plot order in reconstructed legend. It can be either Ascending or Descending. Note that for data plot legend that has never been manually updated, you can also use Graph:Legend:Reverse Order to reverse the data plot entries without the need to reconstruct.
This is only available when Update Mode is set to Reconstruct and Legend is set to One Legend for Whole Page. This controls the plot order to read within a layer.
