- Lab 4 (Solution):
  - You should have done this:
    1. Use `PLOT` to plot `world.shp` in the background. Give the plot an ID of `MYPLOT`.

           nM> plot/bg/id=myplot world.shp
           <Plot should come up in separate window.>
           nM>

    2. Use `REG` to look at the registry entry for plot.

           nM> reg
             T: REG             = Table of 3 entries
             O:  SHELL          = nxm.sys.lib.Shell@c1cd1f
             T:  HANDLERS       = Table of 3 entries
             O:  MYPLOT         = P: PLOT,FILE=world.shp,/BG=,/ID=myplot

    3. Use `RES` to look at the registry table. Note how it is the same as what was shown with `REG`.

           nM> res reg
             T: REG             = Table of 3 entries
             O:  SHELL          = nxm.sys.lib.Shell@c1cd1f
             T:  HANDLERS       = Table of 3 entries
             O:  MYPLOT         = P: PLOT,FILE=world.shp,/BG=,/ID=myplot

    4. Use `RES` to look at the particular entry for the plot. Since `REG` is a table you can use the `REG.<id>` syntax.

           nM> res reg.myplot
             O: REG.MYPLOT      = P: PLOT,FILE=world.shp,/BG=,/ID=myplot

    5. Use `QUERY` to see some of the methods can be called on the plot. Then use QUERY reg.myplot.nextlink to see more methods that can be called on plot.

           nM> query reg.myplot
           <Long list of methods in plot.>
           nM> query reg.myplot.nextlink
           <Long list of methods in MPlot.>

    6. Use `QUERY` and the NeXtMidas API to look at the documentation for the `setView` method that is callable in the plot.

           nM> query reg.myplot.nextlink
           <Long list of methods in MPlot including setView.>

       Next: Look in the NeXtMidas API, click on the "MPlot" class, and look at documentation for the `setView` method.
    7. Set the view to `GEODETIC`. Remember that when a class has a `setFoo(..)` method the value of it can be set using `SET <object>.FOO <value>`.

           nM> set reg.myplot.view GEODETIC
           <Plot should change to a 3D (Geodetic) view.>
           nM>
