To modify the scale legend in a waveform chart programmatically, create Property Nodes for each element of the legend you want to modify. For example, if you want to modify the scale label, right-click the string element in the scale legend and create a Property Node for that element.

PropertyDescription
Active PlotGets or sets the active plot. After you get or set the active plot, you then can set properties or invoke methods that affect only the specified plot. Details
Digital Display(s) VisibleIndicates whether the digital displays for the chart are visible. Details
Digital Display[]Reference(s) to the digital display(s). Details
History DataArray of the history data of a chart. Wire an empty array to this property to clear the chart history. Details
Ignore AttributesIf FALSE (default), the plot names in the plot legend and the scale names on the graph automatically adapt to the plot names and scale names in the dynamic or waveform data attributes. If TRUE, the plot names and scale names do not adapt to the dynamic or waveform data attributes. Change this property to TRUE if you want to change the plot names and scale names. This property applies only to graphs and charts with dynamic or waveform data. Details

Legend:DisableDisables the plot legend at run time. Details
