Plot Basics

The NeXtMidas PLOT command plots the following types of files:

The single NeXtMidas command PLOT does the same thing as all these X-Midas commands combined: xplot, xrtplot, xraster, xrtraster and xgeoplot! PLOT identifies the file type of the first file and applies the appropriate plot type. The type can be overridden with the type= modifier.

The following sections detail a few caveats associated with the NeXtMidas PLOT command.

Stacking Order

By default, layers (or files) are stacked the way they are entered on the command line (first is on the bottom). If Backing Store is used for a layer, that layer(s) is drawn first.

Using Features

See the FEATURE explain file.

Backing Store

Backing store is a mechanism where static layers are drawn without recomputation.

Macro Interface

PLOT (and many NeXtMidas primitives) handle events and send messages to the macro in response to these events. For instance, when the LMB is clicked in a PLOT a MARK message is sent to the macro. See the PLOT explain file for a complete list of messages.
