Hi all,
I have two columns of data, one is normal data and another one is the number of repetitions of the first data. How to plot a histogram by considering the second column of data?
Thank you in advance! |

Hi,
I think there is not a direct way to plot like that. You might try to use some scripts to generate a new column, then plot histogram from there.

Hi,
My colleague wrote the following script for you.
Assume the column 1 is normal data, and column 2 is repetition number. You can try the following script:
int m = wks.maxRows;
int r1 = 1;
int r2 = 1;
Loop(ii,1,m)
{
int t = cell(ii,2);
double x = cell(ii,1);
r2 += t;
Loop(jj,r1,r2)
{
cell(jj,3) = x;
};
r1 += t;
};
Hope it can help.
