How to plot this frequency graph?

Dear all,

I have runoff and precipitation data (as I attached), how I can achieve such a plot?

I tried this script:

histogram2(precipitation,runoff,'Normalization','count')

But it seems wrong and the range of x and y lines doesn't set between 0 to 1. The name of this plot below is bivariate frequency graph which is a histogram of precipitation and runoff.

Thank you in advance

Do you mean something like this?

pn = normalize(precipitation, 'range');
rn = normalize(runoff, 'range');
histogram2(rn, pn)

Yes, Thank you, and why do I have blank mosaics in the plot? is there any way to force it to show zero values, instead of leaving them blank? thank you

load runoff
load precipitation
precipitation = normalize(precipitation, 'range');
runoff = normalize(runoff, 'range');
histogram2(runoff, precipitation, 'Normalization', 'pdf', 'ShowEmptyBins','on');  % for probability density function

Thank you so much
