Replotting data on a common scale

By default, the graph will be stored for replotting. If the `\-REPLOT` qualifier is used, the graph will not be saved for replotting. The default is `\REPLOT`.

To redraw a graph with multiple data sets so that all the data will appear within the axis boundaries, use the `REPLOT` command in association with the `AUTOSCALE` characteristic. For example:

     SET AUTOSCALE ON      ! turn on autoscaling
     SET PLOTSYMBOL -1     ! set plotting character to `box'
     GRAPH X Y             ! plot data with axes
     SET PLOTSYMBOL -2     ! set plotting character to `cross'
     GRAPH\OVERLAY U V     ! overlay another data curve
     CLEAR\-REPLOT         ! clears graphics but not the replot buffers
     REPLOT                ! replot both data sets on common scale

Refer to the `REPLOT` command for more information.
