Current Page: NeXtMidas Training Working with Files Plotting Files PLOT
- - | The `PLOT` Command: `PLOT` is typically run with one or more files as an input. To input multiple files, separate each file by a bar character (`|`).
        nM> plot world.shp|cities.prm
  - Attributes for each layer can be changed in line with the `LAYER={...}` qualifier.
        nM> plot world.shp{TAG=COUNTRIES,LAYER={OPAQ=0,LABEL=NAME}}|&
                     cities.prm{LAYER={COLOR=RED}}
  - - In the above example the qualifiers `LAYER={OPAQ=0,LABEL=NAME}` tells the plot layer to make the opaqueness zero (i.e. transparent) and to show a label on the readout with the `NAME` of the country. By default layer names are automatically set to match the root name of the file. this can be overridden using the `TAG=` qualifier. For example: Because of duplicate tags, only one of files shows up.
          nM> plot world.shp{LAYER={OPAQ=0}}|world.prm
    - This will work.
          nM> plot world.shp{TAG=SHP,LAYER={OPAQ=0}}|world.prm{TAG=PRM}
  - - - In order to use messages, one must add the `/msgid=` switch. (This is discussed more in the module on Macros.) The `PLOT` command takes in a number of command line parameters allowing customization of the plot. Most of these options are settable using `reg.<id>.<option>`. A few examples: Setting Y-axis limits (`Y1`, `Y2`).
            nM> plot/bg/id=myplot fftdemo.prm Y1=50 Y2=150
        or
            nM> plot/bg/id=myplot fftdemo.prm
            nM> set reg.myplot.y1 50
            nM> set reg.myplot.y2 150
      - Setting the view of a map.
            nM> plot/bg/id=myplot nxm.sys.dat.world.prm|cities.prm view=MERCATOR
            nM> set reg.myplot.view LATLON
            nM> set reg.myplot.view GEO
