Note: The grid will be drawn in the current window.

In the LOG and LOGLINEAR rescaling modes, grids will be drawn in decades and the X/Y grid increments will be ignored. In addition, grid lines at 0 (zero) and LOGMIN will be drawn.

Obsolete

is_null()[source]

Check if this is a null (undefined) instance

Returns:

True if this is a null (undefined) instance, False otherwise.
