LOGZPLOT is an easy way to create surface plots with both a log-scaled z-axis and log-scaled coloring. LOGZPLOT creates a plot using SURF, MESH, IMAGE, PCOLOR, TRISURF or TRIMESH, then applies the logarithmic transformation. If called without data inputs, LOGZPLOT will apply the logarithmic scaling to an existing surface plot.

Although creating a plot like LOGZPLOT's output is easy to do from the command line, getting a colorbar to display the correct data range requires some additional scaling of the color data. LOGZPLOT automatically scales the color data so that a colorbar will have a scale corresponding to the input data, even after changing the axes' 'CLim' property. To do this, LOGZPLOT attaches a listener function to the axes that corrects the color data scaling whenever the 'CLim' property changes. This allows the user to specify 'CLim' values in the normal units of the original data.
