Hi, I have not found a post that explains how to create a colorbar for a contour plot with or without filled regions. At the moment, I manage to create a color bar manually as follows.
First, I plot some function like so,
plots[contourplot](i/(1-(1+i)^(-n)), n = 15 .. 30, i = 0.1e-1 .. .15, axes = frame, contours = [seq(0.1e-1*n, n = 5 .. 16)], filledregions = true, axis = [location = low, gridlines = [10, majorlines = 1]], axis = [location = low, gridlines = [10, majorlines = 1]], tickmarks = [10, 10], transparency = .4, legendstyle = [location = right]);
Then, I right click on the plot and select Legend->Show Legend
The option "legendstyle = [location = right]" put into the plot command causes the legend to be display a range of different colors each labeled "Polygons i", where i is some interger. At this point I would manually change the labels to some appropriate numerical value. However, everytime a refresh or modify the plot I must manually change the labels again. This is especially troublesome when using a large number of contours.
My question is threefold.
Is there a way of displaying the filled regions in the legend thorugh the plot command (not through the context sensitive menu)?
Is there a way of manually specifying the appropriate names in the plot command?
Lastly, is there a way of changing the color scheme of these filled regions?
Any help is much appreciated.
