Méthode	Description
AddGraph ( Primitive xpos, Primitive ypos, Primitive width, Primitive height, Primitive title, Primitive labelX, Primitive labelY ) : Primitive	Create a graph.
AddSeriesHistogram ( Primitive graphName, Primitive seriesLabel, Primitive data, Primitive colour ) : void	Add a new data series to an existing graph as a histogram.
AddSeriesLine ( Primitive graphName, Primitive seriesLabel, Primitive data, Primitive colour ) : void	Add a new data series to an existing graph as a line graph.
AddSeriesPoints ( Primitive graphName, Primitive seriesLabel, Primitive data, Primitive colour ) : void	Add a new data series to an existing graph as points.
CreateTrend ( Primitive data, Primitive order ) : Primitive	Create a trend from data.
DeleteSeries ( Primitive graphName, Primitive seriesLabel ) : void	Delete an existing series on existing graph.
ExportCSV ( Primitive data, Primitive fileName ) : void	Export data series directly to CSV file (no graphing).
Help ( ) : void	This function is just to display this help. Graphs of data can be plotted as lines, points or histograms. Each series of data is a SmallBasic array with the array index reprenting the (unique) X value and the array value representing the Y value. For example: data[1] = 5 data[2] = 8 data[3] = 3 First create a graph object with AddGraph, then add series with AddSeriesLine, AddSeriesHistogram or AddSeriesPoints. Once a graph is created and plotted, the axes can be grabbed and scrolled where the hand cursor appears. The legend can also be moved. The graph can be rescaled by using the left mouse button to select a region to zoom, or the mouse wheel can be used to zoom the display. A double click will reset the scaling to the original default. A right click will bring up a menu with other features like export of image or data, displaying the cursor coordinates, hiding the legend etc. Finally the various parmeters for this method give further control of the plotting colours and behaviour.
RestartEvents ( ) : void	Restart all the graph left click mouse events.
ScaleAxisX ( Primitive graphName, Primitive min, Primitive interval, Primitive max ) : void	Set the X axis scaling. This over-rides any automatic methods.
ScaleAxisY ( Primitive graphName, Primitive min, Primitive interval, Primitive max ) : void	Set the Y axis scaling. This over-rides any automatic methods.
StopEvents ( ) : void	Stop all the graph left click mouse events.
TrendCoef ( ) : Primitive	Get the polynomial trend line coefficients for the last calculated trend using CreateTrend.
