%ZEN.SVGComponent.lineChart

class %ZEN.SVGComponent.lineChart extends %ZEN.SVGComponent.chart

This is an SVG chart component that displays a line chart.
This chart displays one or more data series as a set of lines.
If there are multiple data series, the lines are either superimposed or or stacked atop one another, as specified by the chartStacked property.
You can use the chartFilled property to specify that the area under the lines should be filled, turning this into an area chart.
You can view pivot the chart using the chartPivot property.
