I need zero to be yellow and 1 to be green but it is opposite in the heatmap now:

You can flip the colormap summer to get your desired colorscheme.
f = figure;
a = heatmap(rand(10,10),'Parent',f);
colormap(f,flipud(summer));

Hi, i need something similar. I used HeatMap function ad i obtained the two charts in attachment. The max values for the two charts are 1 an 0.857. On the two charts the maxi values (1 and 0.857) have the same color green. I need to rescale the second chart to the maximum value 1 in order to obtain the same colours for the same values in the two charts.
