HelpgdPlotGraph takes user input in a script-like format, with one command per line. For example, fill white - set the background to white axis R 0 100 20 - the R axis goes from 0 to 100 and should be marked at intervals of 20 axispi THETA -100 100 - the THETA axis goes from -100pi to 100pi and should not be marked axispair_polar R THETA - we're doing polar equations using R as the radius and THETA as the angle equationplot r=2t 10000 - plot the equation R=2 * THETA using 10,000 samples drawaxes - draw the axes (in this case circles of radius 20, 40, 60, 80 and 100) end - quit |
