If the AutoScale box is checked on the Quick Entry screen, FX Graph will automatically detect any points of interest (local maxima and minima, x intercepts and intersections) from -500 to 500 and adjust the axes so that all of the points of interest are visible. Once you have selected Autoscaling, FX Graph takes full responsibility for the axes. Please note that the autoscaling feature slows down the response time of FX Graph.
