Pareto Charts
In This Topic
A pareto chart contains both bars and a line graph. Individual values are represented in descending order by bars and the cumulative total is represented by a line. The pareto chart is used to highlight the most important items in a set of values.
You can use the ParetoSeries class and the YPlotArea class to create a pareto chart.
For information about creating charts in the Spread Designer or the Chart Designer, refer to Adding a Chart Control or Using the Chart Designer.
Using Code
- Add data for the chart.
- Specify the series with the ParetoSeries class.
- Add the chart.
