Hi,

I am using a for loop over some weather data to indicate severity of a thunderstorm situation, see the code below.

I am wondering now, if I display the image with imagesc(), is there a way that by clicking on the pixel, the reason why this value is assigned will be displayed?

For example, if I click on a pixel with value 1, it would display a text box saying "because 10 < cape < 750 and shear < 20"

Thanks!

for i = 1:size(cape_fin,1)
    for j = 1:size(cape_fin,2)
        if cape_fin(i,j) > 10 && cape_fin(i,j) < 750 && shear_fin(i,j) < 20 
            hail_prob_level_fin(i,j) = 1;
        elseif cape_fin(i,j) > 10 && cape_fin(i,j) < 750 && shear_fin(i,j) > 20 && shear_fin(i,j) < 40
            hail_prob_level_fin(i,j) = 2;
        elseif cape_fin(i,j) > 10 && cape_fin(i,j) < 750 && shear_fin(i,j) > 40
            hail_prob_level_fin(i,j) = 3;
        elseif cape_fin(i,j) > 750 && cape_fin(i,j) < 1300 && shear_fin(i,j) > 20 && shear_fin(i,j) < 40 && tlr_600_800_fin(i,j) < 6.6 || tlr_500_700_fin(i,j) < 7.3
