MATLAB: Contourf with more colours

colormapcontourf

With the function contourf I created the picture below. I would like to have more color gradations in it. I succeeded in the colorbar.

Does anyone have an idea?

You can specify the 4 input argument to contourf() to specify the number of levels you want.

contourf(x,y,z,50); % 50 levels will be created

MATLAB: How to remove colorbar and heatmap black borders

If you want to remove the colorbar, you can set the ColorbarVisible property to 'off':

h = heatmap(magic(5));
h.ColorbarVisible = 'off';

Alternatively, use the colorbar command:

heatmap(magic(5))
colorbar off

Heatmap does not provide any control over the borders around each cell, so if you want to remove the borders, you will have to switch to a lower-level function like image or surface.

MATLAB: Contourf with irregular spaced points

You will need to use something like TriScatteredInterp over a regular grid and contour that. contour() and contourf() are not suitable for scattered points.
