 * will be ignored but if you set some values Axis will switch to manual mode. Change how axis labels are displayed by
 * changing formatter {@link #setFormatter(ValueFormatter)}. Axis can have a name that should be displayed next to
 * labels(that depends on renderer implementation), you can change name using {@link #setName(String)}, by default axis
 * name is empty and therefore not displayed.
