Is there a way I could flip the height to start from zero and also change the position of the plot in the same direction?

pts1 = linspace(0, 40, 41); % for heights
pts2 = linspace(-25, 70, 96); % for dBZ
N = histcounts2(heights(:), data.Z(:), pts1, pts2);
% 2D density plot
figure(1)
imagesc(pts2, pts1, N)
colorbar
set(gca,'ColorScale','log')
ylabel('Heights (Km)')
xlabel('(dBZ)')
title('CFAD')
grid on 
caxis([0.1 10000])
colormap("jet")
