PLOTIMAGE - L3Harris Geospatial
WebThe PLOT function draws a line plot of vector arguments. If one parameter is used, the vector parameter is plotted on the ordinate versus the point number on the abscissa. To plot one vector as a function of another, use two parameters. Instead of data, you can also input an equation of X using either the input argument or the EQUATION property.

The syntax is very similar to the PLOT command, in the sense that an XRANGE and YRANGE for the plot can be. specified. PLOTIMAGE keeps separate the notions of the image coordinate. system and the displayed coordinate system, which allows any input. lilly pilly moe florist
