Description

The BarLineChartExpression inherits from BarChartExpression, StackedCategoricalChartExpression, CategoricalChartExpression and AbstractChartExpression.

The additional properties added by this expression support setting values for the line series and second range axis that render the line portion of the chart. The similar properties in the bar chart sets the values for the bar series. This expression is also unique in that it requires two data collector functions - one for the bar series and one for the line series. The bar data is recognized by the standard datasource property, while the line data is recognized by the linesDataSource property, detailed below.
