Parameters:

• pump (wntr.network.elements.Pump object) – Pump

• title (string, optional) – Plot title

• xmin (float, optional) – X axis minimum

• xmax (float, optional) – X axis maximum

• ymin (float, optional) – Y axis minimum

• ymax (float, optional) – Y axis maximum

• xlabel (string, optional) – X axis label

• ylabel (string, optional) – Y axis label

• ax (matplotlib axes object, optional) – Axes for plotting (None indicates that a new figure with a single axes will be used)

Returns:

ax

Return type:

matplotlib axes object
