Plotting a parameter 'map' in octave

Question

I want to be able to plot a 2d grid of points onto a parameter plane. I want to plot each of the points, but plot it in a different way depending on what result the parameters/co-ordinates of that point lead to. The general effect I'm looking for is a sort of map, where one can point to a place in the plot and say 'In this region of parameter space, we see X happening', like how a Pourbaix diagram works, but with more colour. Is there a fast and efficient way of doing this sort of grid plotting in octave?

没有具体的示例，很难给出确切的答案，但是我认为您只需要使用imagesc()绘制网格并找到合适的颜色图即可。
