thanks that gets close but not quite. My code is:
clabel(Cf,h)
colormap(hsv(256))
ah = colorbar('vert')
title('Rock Resisitivty from Hibernia B16_17');
xlabel('Porosity','fontname','bookman','fontsize',11)
ylabel('Water Saturation S
_w','fontname','bookman','fontsize',11)
hold off;
grid on;
set(ah, 'YTickLabel', num2str(10 .^ get(ah, 'YTick')));
The color bar label are all 10 31.62
It look like it is trying to put all o fthe labels (7 in
all) on each tick mark?
