This how i want the plot to be

[Walter Roberson]

It is not clear what your question is?

I note that you tagged with "3d plot", but that looks like a 2D plot.

pcolor(x,y,I),shading flat,xlabel('x-text'),ylabel('y-text'),colorbar

Answer 2

Hi idowu Abdul-Semiu,

There are several plot-commands that support the image you are showing. Have a look for the following commands:

• imagesc()
• contourf()

You would have to adjust the display options of the plot-commands, e.g. remove the contour lines in contourf() and change the colormap.

Read and try. If you have troubles to adjust the plot, provide the grid and/or data matrices and post the code you have tried so far.

Kind regards,

Robert

Since you have spread similar questions across several places, without good organization (and one of them was closed), I'll post here.

For the code I helped you with, that produced X,Y,Z, the following will produce a contour plot of the style above:

figure; contour(X,Y,Z,'fill','on')
colorbar

For comparison, the following is the mesh version, so this "boring" plot is expected.
