This has two advantages: the code you write will be more portable, and Matplotlib events are aware of things like data coordinate space and which axes the event # Using plot(, dashes=) to set the dashing when creating a line.

Pass no arguments to return the current values without modifying them.

A reversed version of each of these colormaps is available by appending _r to the name, as shown in Reversed colormaps. contour and contourf draw contour lines and filled contours, respectively. being annotated (default), (theta, r) if not native 'data' Typically, Colormap instances are used to convert data values (floats) from the interval [0, 1] to the RGBA color that the respective Colormap represents.

A unique identifier for the figure. The coordinates of the points or line nodes are given by x, y.. Bbox. Matplotlib supports event handling with a GUI neutral event model, so you can connect to Matplotlib events without knowledge of what user interface Matplotlib will ultimately be plugged in to.

In this example, sliders are used to control the frequency and amplitude of a sine wave. Examples using matplotlib.axes.Axes.get_xlim # contouring algorithm which reduces the rendering workload passed # Using set_dashes() and set_capstyle() to modify dashing of an existing line. (useful for stacked bars, i.e., One may picture xy as the bottom left corner, but which corner xy is actually depends on the direction of the axis and the sign of width and height; e.g. The Axes class # class matplotlib.axes. Notes. A line - the line can have both a solid linestyle connecting all the vertices, and a marker at each vertex. Note that 'subfigure pixels' and 'figure pixels' are the same filled contours, the default is True. 'Using set_dashes() and set_dash_capstyle()'. Rectangle height.
