- Lab 4:
- This lab will introduce you to using the
PLOT command.
- What you need to do:
- Use
PLOT to plot the file apenny.prm .
- Use
PLOT to plot the file
original: http://nextmidas.com/nm/nxm/sys/dat/apenny.prm (currently unavailable)
alternate: file:///opt/midas/nxmlatest/nxm/sys/dat/apenny.prm
(where /opt/midas/nxmlatest is a softlink to your local nxm installation)
- Use
PLOT to plot the world.shp and cities.prm
files at the same time.
- With the plot still up from the previous exercise, use the middle mouse button
to disable the
cities layer. Now enable the layer.
Can you figure out how to turn off the on-axis readout?
- Use the "Plotting Maps from a NeXtMidas Map Server (NMS)" section in the
PLOT
explain file to bring up a map of the world with the BLUEMARBLE background.
Use the server nextmidas.com (currently unavailable) and the port 8080
(You need Internet access for this).
Hint: To get a full list of available VIEWs
look in the NeXtMidas API at the "MPlot" class , and look at documentation
for the viewList field.
PLOT apenny in the background. Then use the FEATURE command to
place a box around Lincoln's nose.
