Hello,

I have 10 categories, each one contains several data in each row. How will I read these data with each category for plotting bar chart with error bars?

Hi Walter,

I attach the data in which I want to plot (x = column B: there are 10 sites) and (y = column O, the mean value) and error bar (column P) for 7 years (column A). The plot result is as the results file.

Could you help me how to do this?

Thank you,

Kevin Nguyen
