Drawing Line Plots
Syntax gplot(y)
gplot(xy)
gplot(xyz)
See Also gaddview , gxyzaxis , and gplot(x, y, style)

Description
Plots a curve for each column of y, where y is an integer, real, or double-precision matrix specifying the y value for each point. The first column correspond to a curve with the next color in the current color sequence , the second column corresponds to the following color and so on. If x is not present, i is the x value corresponding to y(i,j). If z is not present, 0 is the z value corresponding to y(i,j).

If x is present, it is an integer, real, or double-precision matrix and has same number of rows as y. If x is a column vector, x(i) is the x value corresponding to y(i,j). Otherwise x also has the same number of columns as y and x(i,j) is the x value corresponding to y(i,j).

If z is present, it is an integer, real, or double-precision matrix and has same number of rows as y. If z is a column vector, z(i) is the z value corresponding to y(i,j). Otherwise z also has the same number of columns as y and z(i,j) is the z value corresponding to y(i,j).

The current line style, width and symbol size are determined by the previous call to the gstyle function.

Example
If you enter
     ginit
     x      = 0. : .1 : 2 * pi
     y      = [sin(x), cos(x)]
     gplot(y)
O-Matrix will draw with the following plot



If you enter
     ginit
     x      = 0. : .1 : 2 * pi
     y      = [sin(x), cos(x)]
     gplot(x, y)
O-Matrix will draw the following plot



If you enter
     ginit
     y      = 0. : .01 : 2 * pi
     z      = cos(4 * y)
     x      = sin(4 * y)
     gplot(x, y, z)
     grotate(30, 0, 70)
     gxtitle("x")
     gytitle("y")
     gztitle("z")
O-Matrix will draw the following plot
