Spline with multiple series Part of PowerCharts XT

A multi-series spline chart is a specialized form of the multi-series line chart that can be used for plotting data for multiple categories of data that requires the usage of curve-fitting. Like the multi-series line chart, data values are plotted as data points. However, instead of using straight line segments to connect the data points, this chart draws a fitted curve to connect the data points. This chart can be used for applications such as rendering the impulse-response for multiple systems or the development lifecycle for multiple products.

Best practices:

  • Use the multi-series spline chart to show gradual changes in data, instead of spikes.
  • Use the legend and y-Axis labels to improve readability.
  • Use trend-lines to add more insights to the data plotted.
