Pareto Charts

Pareto analysis is a technique used to identify the relative importance of problems and conditions. The Pareto chart is a frequency histogram ordered from highest to lowestCitectSCADA automatically orders the bars at run-time. The data for each bar in the histogram represents one CitectSCADA variable - as defined in Variable Tags. Do not use SPC tags.

Note: Typically the frequency in a histogram is of integer type, though you can use floating point types if you want. Negative values are not valid.
