Axes Configuration

Horizontal axis Range

Sets the range for the horizontal axis scale. Note that you can use the predefined functions and constants (see the section called “Predefined Function Names and Constants”) as the extremes of the range (e.g., set Min: to 2*pi). You can even use functions you have defined to set the extremes of the axis range. For example, if you have defined a function f(x) = x^2, you could set Min: to f(3), which would make the lower end of the range equal to 9.

Vertical axis Range

Sets the range for the vertical axis. See Horizontal axis Range above.

Horizontal axis Grid Spacing

This controls the spacing between grid lines in the horizontal direction. If Automatic is selected, then KmPlot will try to find a grid line spacing of about two centimeters that is also numerically nice. If Custom is selected, then you can enter the horizontal grid spacing. This value will be used regardless of the zoom. For example, if a value of 0.5 is entered, and the x range is 0 to 8, then 16 grid lines will be shown.

Vertical axis Grid Spacing

This controls the spacing between grid lines in the vertical direction. See Horizontal axis Grid Spacing above.
