Hey!!

I am counting particles so I need to plot an histogram for the diameter but I cannot control how it counts the values.
I have values such as 12, 12.1, 12.2, 12.3, etc. When I count the values with excel, i.e, it create values groups from, i.e., 12,1 to 12,5 in one group, and from 12.6 to 13 in another one. I am not able to get the same plot with Origin. How can I choose how it considers the values for the histogram? I have been playing with bin size, bin begin and end and it is still impossible...

Thank you so much in advance!

Susana

Instead of directly plotting data as histogram, you can use Frequency Count under Decretive Statistics, then choose

Specify Binning Range by = User-Defined Boundaries

and specify the column that contains the boundary data.

See
