A CL example

In order to start PONGO you must first start CL and load the pongo package.

In any PONGO session the first action is to open the plotting device. This is done by typing⁴:

po> begplot xw

Where `xw' should be replaced by the name of the plotting device you are intending to use. The data may then be read using the command:

po> readf data=pongoexamples$tutorial.dat xcol=1 ycol=3 all=yes

Plotting limits are set up using the range of the data by the command:

po> dlimits

Axes for the plot may be drawn using:

po> boxframe

and finally the points may be plotted as asterisk-like symbols and the axes labelled with:

po> points 3
po> label "X axis" "Y axis" "Plot Title"

To close a device and end a PONGO plot the command: ENDPLOT should be used.
