how to change the colorbar spacing

I want to make a plot like this.

I used the PCOLOR and CAXIS function ([0 10]) to set the range. But I want the rank from 0 to 300, but that each level or label increases in a different way to linear.

How can I edit the increase in the spacing of the colored bar of the plot?

My plot in this moment is this:

But the Cscale isn't what I need.

You say you want "each level or label increases in a different way to linear". OK, no problem but you have to define that different way. Do you have some formula for it, like a gamma or log or something? If so, what is it?

Yes, I need that the result to increase in a different way to the linear, for example in an exponential way. I understand the map matrix in color bar have to be defined, but I don't got how to do that.

Hi,

You could use the 'TickLabels' property of colorbar to put the labels which you need in the places where you would like to have.

colorbar('Ticks',[0,50,100,150,200,300],...
         'TickLabels',{'0.0','3.0','4.0','5.2','15.0', '300'}) 

Refer to the following link for more information on colorbar and also have a look at other examples given in the link for more info.

It doesn't work.

My result is bad.
