AddFunctionPlot2 Method
The AddFunctionPlot2 method adds a 2D function plot to an existing 2D graph, equivalent to Graph | Add to Graph | Plot. Returns an AutoFunctionPlot object.
Syntax
object.AddFunctionPlot2( Type, function1, function2, firstValue, lastValue, xAxis, yAxis, id )
| Parameter | Type | Description |
| Type | grfFunctionPlotType | required, function plot type (Y=F(X), X=F(Y), or parametric) |
| function1 | String | required, function to plot (y=f(x), x=f(y), or |
| function2 | Variant | optional, function to plot ( y=g(T) if type is parametric; otherwise ignored) |
| firstValue | Variant | optional, first value to evaluate the function(s) at, default = 0 |
| lastValue | Variant | optional, last value to evaluate the function(s) at, default = 25 |
| id | Variant | optional, plot name |
Remarks
2D graphs can only be added to other 2D graphs. See Mathematical Functions for information on writing function equations.
Example 1
This example shows how to add a function plot.
Graph1.AddFunctionPlot2( grfFunctionPlotYX, "2+x")
Example 2
This example shows how to add a parametric function plot.
Graph1.AddFunctionPlot2( grfFunctionPlotParametric, "2+cos(T)", "4*T")
Example 3
This example shows how to create an XY function plot.
Graph1.AddFunctionPlot2( grfFunctionPlotXY, "2*y")
