Adds a new curve to an existing plot.

Syntax

g = AddCurve()

g = AddCurve(PlotId)

Arguments

Name

Description

PlotId

Optional argument.

The ID (integer value) of the plot.  If omitted, the current plot is used.

Outputs

Name

Description

g

Optional argument.

The curve ID (integer).

Example

In an existing plot, add a new curve and then add points to the curve.

Syntax

PlotLine([1 3],[1 3])

PlotLine([1 3],[2 3],'new')

PlotLine([1 2],[2 3])

AddPoint(2,2,1.3,1.6)

AddCurve(2)   // will add the curve in the second plot

AddPoint(2,3, 1.3, 1.6)  // will add point to the curve created above

AddPoint(2,3, 1.4, 1.6)

AddCurve()    // will add the curve in the current plot

AddPoint(2,2, 1.4, 1.7)

AddCurve(1)   // will add the curve in the first plot

AddPoint(1,2, 1.5, 1.8)

Comments

AddCurve() is used together with AddPoint().

If you use DeletePlot(), the plot counter is not decremented.  It is possible to use plot handles to avoid issues:

r=PlotLine([1 3],[1 3])

s=PlotLine([1 3],[2 3],'new')

s=PlotLine([1 2],[2 4])

AddPoint(s,2,1.3,1.6)

AddCurve(s)   // will add the curve in the second plot

AddPoint(s,3, 1.3, 1.6)  // will add point to the curve created above

AddPoint(s,3, 1.4, 1.6)

AddCurve()    // will add the curve in the current plot

AddPoint(s,2, 1.4, 1.7)

AddCurve(r)   // will add the curve in the first plot

AddPoint(r,2, 1.5, 1.8)
