Color maps and the scale of axes september 26th, 2011 8 comments if you have not only some data points or a line to plot but a whole matrix, you could plot its values using different colors as shown in the example plot in fig. I cant seem to get set view equal xy to work on any terminal.
In addition, the grid is always rectangular in size and not circular. Of course this works best with scale factors relatively close to 1. Logarithmic scale of horizontal axis gives spectra of bodies emitting radiation due to their temperature. If you want to do the same with your data set you should maybe spent a little bit more effort on. Hi guys, i have one question concerning polar plots.
Scale values less than 1 will cause the plot to not fill the entire canvas. It isnt smart enough to know it could expand out the visual range and zoom a bit even if that means it has to offset in this case the y axis. A pcolor plot draws rectangles with colors from the matrix c over the twodimensional region represented by the matrices x and y.

For all linux distros, read the file install for instructions. Sometimes our curves can or should not share the same yaxis. Autoscaling works the same way for polar mode as it does for parametric mode for plot, with the extension that in polar mode set dummy can be used to change the independent variable from t see set dummy p. I have the x and y axes with large numbers, 2000, etc. Ethan a merritt and many others major contributors alphabetic order.
