Line Chart

Lines are used to display information in line charts. There are three different types, normal, stacked, and 100% Stacked.

Normal

Normal Line charts create lines based on the data. They use DateTimeXAxis or IndexedXAxis as the XAxis based on the series and NumericYAxis as the YAxis.

Stacked

Stacked charts show related data, one on top of the other. They use DateTimeXAxis or IndexedXAxis as the XAxis based on the series and NumericYAxis as the YAxis.

100% Stacked

100% stacked charts are similar to stacked charts, but here the data is expressed as a percentage. They use DateTimeXAxis or IndexedXAxis as the XAxis based on the series and PercentageYAxis as the YAxis.
