Without any adjustments, the labels would be hidden by the axes by default. We then draw our sinewaves on the axes directly (rather than using the shortcut plt.plot()).

To learn more about how to create subplots, see the add_subplot definition. We name these handles ax1 and ax2 (for axes 1 and 2). (2, 1, 2) similarly says that in the same 2x1 gird, return a handle to the second subplot (the one on bottom). (2, 1, 1) says to create a 2x1 subplot grid (2 high, 1 across) and return a handle to the first subplot (the one on top).
Raspberry pi install matplotlib series#
The add_subplot() function must be given a series of numbers (or a 3-digit integer) representing the height, width, and position of the subplot to create.

We can then use the fig handle to create subplots on the figure. To create subplots, we need to explicitly create that figure so that we get a handle to it. In reality, this is a shortcut to create a figure object (the background where we draw our plots) and then create a set of axes on a single plot on that figure. Up to this point, we had been calling plt.plot() to draw on the canvas.

Run this, and you should get two sinewaves, each in its own subplot. # We can use the subplots_adjust function to change the space between subplots # Adding labels to subplots is a little different # Draw our sinewaves on the different subplots # Explicitly create our figure and subplots To accomplish this, we can use supblots: language:python Sometimes, you may want to display multiple plots on a single image (or figure). Refer to the pyplot documentation to see all the available functions for plotting and formatting.

This saves the current figure as an image in the same directory as the Python code (and we can do it programmatically!) See the Notes section in the plot documentation to see the various options for formatting strings.įinally, we were able to create the image above by calling plt.savefig(). 'b-' says to make the plot blue (b) and use a dashed line (-). 'r^' says to make the points red (r) and appear as triangles (^). We can also show a legend by adding label= as an argument in the plt.plot() function call.Īdditionally, if you look at our call to plt.plot(), you'll notice that we can specify how we want the plots to look with the third parameter. We're able to add a title and axis labels. We can "zoom" by setting the limit on the axes with plt.axis(). When it comes to formatting the graph, we have plenty of options at our fingertips. When you installed the matplotlib package, numpy was installed by default! If you are looking for a free MATLAB replacement, numpy is a good contender. The numpy package is a great way to work with arrays, and it offers an impressive speed boost over native Python methods. Note: As it turns out, Python does not have many easy ways to interact with lists or arrays. You should see two different sinewaves overlapping each other. Like any good graph-creation tool, pyplot lets you change the formatting of your graphs with legends, titles, and labels. Pyplot automatically draws a line between one point and the next in the series. ys) make up the first point, (0, 1) in this instance. Note that the points from the xs and ys lists are related to each other. If you want to save the image, you can click on the Save icon in the plot's window. While the basic line graph is likely the most used graph, matplotlib is also capable of plotting other types of graphs, including bar, histogram, scatter, and pie (among others).

You should see the graph appear in a new window. Use your favorite text editor or Python IDE to enter the following code: language:python The first list is a collection of numbers in the X domain, and the second is a collection of numbers in the Y range. Note that the 2 lists need to have the same length (same number of elements). We can provide 2 lists of numbers to pyplot, and it will create a graph with them. The easiest way to make a graph is to use the pyplot module within matplotlib. It operates very similarly to the MATLAB plotting tools, so if you are familiar with MATLAB, matplotlib is easy to pick up.

Matplotlib is a wonderful tool for creating quick and professional graphs with Python.
