want to show a chart with count of error on y, and standard deviation group of error on x
error is a field already in table, need to calculate standard deviation group on front end. I know i can do it in the back end, but i what to keep standard dev dynamic based on selected criteria.
outcome of the chart in table format:
say standard devation is 2, and mean is 20
stdev group error range
Your buckets are not of equal size, which is not supported by the class function.
You can create two variables vSTD and vAVG:
and then a chart with a calculated dimension
=class(error, vSTD, 'error', vAVG)
and an expression
to show a histogram with buckets of size of the standard deviation grouped around the mean value.
