![]() The table below shows common commands to build plots using Matplotlib's object-oriented interface. The next code section demonstrates how to build a multi-line plot with Matplotlib's object-oriented interface. In this case, ax is the object and plot is the attribute. We add a plot attribute (a line) to our axis object ax using the object-oriented structure. NumPy arrays or Python lists x, y, and z can be added to axis object ax. We add attributes to the axis object to build a plot. We instantiated a figure object and axis object, now both of these objects need attributes. boxplot (datadf, x' team ', y' assists ', axaxes0,1). boxplot (datadf, x' team ', y' points ', axaxes0,0) sns. ![]() subplots (2, 2) create chart in each subplot sns. define dimensions of subplots (rows, columns) fig, axes plt. Note these two outputs of the plt.subplots() function are separated by a comma. You can use the following basic syntax to create subplots in the seaborn data visualization library in Python. By convention we'll call the figure object fig and the axis object ax. By default, the subplot() function creates a single figure object and a single axis object. For now, we'll leave the subplot() arguments blank. ![]() We say the plt.subplot() function instantiates a figure object and instantiates an axis object. The plt.subplot() function creates both a figure object and axis objects. Matplotlib's plt.subplot() function is used to build figure objects. Data objects: data points, lines, shapes are plotted on an axis.An Axis contains daughter attributes like axis labels, tick labels, and line thickness. Axis can be thought of as sets of x and y axis that lines and bars are drawn on. Axis objects: An axis is added to a plot layer.If there are multiple plots, each plot is called a subplot. Plot objects: A plot builds on the figure layer.A figure window can include one plot or multiple plots. Think of the figure object as the figure window which contains the minimize, maximize, and close buttons. The basic anatomy of a Matplotlib plot includes a couple of layers, each of these layers is a Python object: Once an object is created, or instantiated, the properties of that object can be modified, and methods can be called on that object. To create a new object is called instantiation. The Matplotlib's object-oriented interfaceĪn object-oriented plotting interface is an interface where components of the plot (like the axis, title, lines, markers, tick labels, etc.) are treated as programmatic objects that have attributes and methods associated with them. The object-oriented approach to building plots is used in the rest of this chapter. This section also introduces Matplotlib's object-oriented approach to building plots. This section builds upon the work in the previous section where a plot with one line was created. Multi-line plots are created using Matplotlib's pyplot library. This takes a number of rows, a number of columns, and then the number of the subplot, where subplots are numbered. Problem Solving with Python Book Construction You can create subplots with plt.subplot(). The Matplotlib's object-oriented interface
