Hello everybody
I have Rain and DI values for 40 years and I want to plot deviation of individual years from the mean similar to this plot. How can I determine deviation of each year from the mean based on number of siga(6 sigma). I have put the rain values in the attachment.
Thanks in advance

You can use the mean and std function to get the mean and standard deviation of your timeseries data. You can then use a formula like (data-mean)/standard deviation to get the deviation of your data in multiple of sigmas. Then use the plot function to plot the deviations along with the data.
