- Are all 3 data sets combined or separate?
- Are there 5 bins total or 5 for each data set (total of 15)?
- What do you mean by the width must be 4?

Hi all,
I am trying to plot a histogram which I have three different sets of data in the same range. However, I attatched both code and excel file of the data. I want to plot all three sets having 5 bins and width must be 4. Showing each set with different color.
Thanks,

Sorry, but it's not clear to me yet what it is you want to achieve.

Taking a stab at this anyway. You cannot group data in histograms. For that, you'll need to use a bar plot. Use histcounts to get the data you need to create the histograms using bar.
Here's a first approach. Note that readtable uses the column headers to create variable names. The warning is because some of these header names are not valid variable names. You can follow the suggestion(s) in the warning or ignore it.
annularrimx = readtable('all_droplets.xlsx');
edges = 0:4:20;
[N,edges] = histcounts(annularrimx.sept_18V1_2,edges);
[N1,edges] = histcounts(annularrimx.oct_2V1,edges);
[N2,edges] = histcounts(annularrimx.sept_30V1,edges);
bar([N;N1;N2]')
xlabel('Diameter of droplet');
ylabel('number of droplet');
xticklabels(string(edges(1:end-1)) + "-" +string(edges(2:end)))
legend(annularrimx.Properties.VariableNames([8 6 4]),'Interpreter',"none")
