Re: returning frequencies (y-axis values) for histograms

Hi Neil,

There are several attributes returned by gsn_histogram. Maybe want you want is the "NumInBins" attribute.

For more information on other attributes returned, see:

In order to plot the best fit line, I will need to know the frequency (the y-axis values) that is found for each binned wind speed (prescribed x-axis values). I am stuck, however, on printing the frequencies that correspond to each bin interval.
