CPlotView:CountSeries

The Count method returns the number of plot series in the CPlotView window.

nSeries = CPlotView:CountSeries()

On success, this method returns nSeries > 0.

On failure, this method returns 0.

The following script plots some points in a CPlotView. It then returns the number of plots series in the plot window:

V = new_plotview()	-- create a CPlotView
V:Add( 25, 66.5)	-- add a point to the plot data
...	-- add 99 more points
V:PlotPoints()	-- plot 100 points in a new plot window
V:Empty()	-- empty all the points
V:Add( 20, 51.4)	-- add 1 point to the plot data
V:AddSeries()	-- plot the point as a new series
n = CountSeries()	-- count the number of series
Printf( "n = %d", n)	-- result: n = 2
