void CrossAt (x, y) AXESDRAW.C Level 1
float x The location along the x axis where the axes meet.
float y The location along the y axis where the axes meet.
CrossAt() allows you to specify the location along the axes where they will meet. If the location you specify is not in the visible part of the plot the axes will cross at the lower-left corner. CrossAt() calls cross(1). Crossed axes are turned off at the end of each plot.
