Re: [ferret_users] Setting shade palette then using PPL

There are two options:

1) Issue a plotting command for immediate execution using the default labels and etc.

2) Set up for later execution with the /SET qualifier. Do this if you want to issue plot customization commands. Following the customizations, draw the plot with PPL SHADE, PLOT, FILL, etc

Customizations could be specifying the axis label formats or label text that are particular to the plot and not persistent.
