Sorry, something went wrong.
This relates to line contours only, not to filled contours. This handles the case where an empty array is provided as the "levels" kwarg, or where for any reason there are no levels within the data range. An example is the case of uniform z. The levels array is then set to the minimum value of z so that the plotting can proceed, and a warning is generated.
