PLOTCOMB Procedure

Creates a comb plot of an input signal.

Usage

PLOTCOMB, signal

PLOTCOMB, abscissa, signal

Input Parameters

abscissa—A one-dimensional array containing the abscissa of the signal to be plotted.

signal—A one-dimensional array containing the signal to be plotted.

Keywords

Color—Specifies the index of the plot color to use for the comb plot.

Title—A string containing the title above the plot.

Xrange—Two-element array containing desired data range for the x-axis.

Xtitle—A string containing the title of the x-axis.

Yrange—Two-element array containing desired data range for the y-axis.

Ytitle—A string containing the title of the y-axis.

Discussion

PLOTCOMB uses PLOT and OPLOT to produce a comb plot. Keywords can be used to add a plot title, axis titles, and to specify the range of the axis to be plotted.

Example

In this example, a comb plot is created for a combined sinusoidal signal.

The results are shown in Comb Plot of Combined Sinusoidal Signal.

t = FINDGEN(50)/49

; Generate the comb plot of the signal.

PLOTCOMB, t, SIN(2*!Pi*t) + .5*COS(6*!Pi*t)
