7.2. Axes of coordinatesOften in mathematical documents, graphs of equations are shown, not withthe complete coordinate grid, but only with the x and y axes as shown below:Plotting TricksFunction plottingAxes of coordinatesData plotting2-2-11-1-21 2Online L A TEX TutorialPart II – GraphicsPSTricksWe can draw such axes using \psline, but pst-plot also includes the command\psaxes to draw such axes more conveniently.7.2.1. Drawing the axesThe command\psaxes(x 0 , y 0 )(x 1 , y 1 )(x 2 , y 2 )draws x and y axes with the x-axis from x 1 to x 2 and the y-axis from y 1 to y 2with the origin (for the axes) at (x 0 , y 0 ); that is, the axes are enclosed in an(imaginary) rectangle with opposite corners at (x 1 , y 1 ) and (x 2 , y 2 ) and the axesintersect at (x 0 , y 0 ).
