# Sample plots in Matplotlib

Here you’ll find a host of example plots with the code that generated them.

## Line Plot

Here’s how to create a line plot with text labels using `plot()`.

Simple Plot

## Subplot demo

Multiple axes (i.e. subplots) are created with the `subplot()` command:

Subplot

## Histograms

The `hist()` command automatically generates histograms and returns the bin counts or probabilities:

Histogram Features

## Path demo

You can add arbitrary paths in Matplotlib using the `matplotlib.path` module:

Path Patch

## mplot3d

The mplot3d toolkit (see Getting started and mplot3d toolkit) has support for simple 3d graphs including surface, wireframe, scatter, and bar charts.

Surface3d

Thanks to John Porter, Jonathon Taylor, Reinier Heeres, and Ben Root for the `mplot3d` toolkit. This toolkit is included with all standard Matplotlib installs.

## Streamplot

The `streamplot()` function plots the streamlines of a vector field. In addition to simply plotting the streamlines, it allows you to map the colors and/or line widths of streamlines to a separate parameter, such as the speed or local intensity of the vector field.

Plot Streamplot

This feature complements the `quiver()` function for plotting vector fields. Thanks to Tom Flannaghan and Tony Yu for adding the streamplot function.

## Ellipses

In support of the Phoenix mission to Mars (which used Matplotlib to display ground tracking of spacecraft), Michael Droettboom built on work by Charlie Moad to provide an extremely accurate 8-spline approximation to elliptical arcs (see `Arc`), which are insensitive to zoom level.

Ellipse Demo

## Bar charts

Use the `bar()` command to make bar charts, which includes customizations such as error bars:

Barchart Demo

You can also create stacked bars (bar_stacked.py), or horizontal bar charts (barh.py).

## Pie charts

The `pie()` command allows you to create pie charts. Optional features include auto-labeling the percentage of area, exploding one or more wedges from the center of the pie, and a shadow effect. Take a close look at the attached code, which generates this figure in just a few lines of code.

Pie Features

## Table demo

The `table()` command adds a text table to an axes.

Table Demo

## Scatter demo

The `scatter()` command makes a scatter plot with (optional) size and color arguments. This example plots changes in Google’s stock price, with marker sizes reflecting the trading volume and colors varying with time. Here, the alpha attribute is used to make semitransparent circle markers.

Scatter Demo2

## Slider demo

Matplotlib has basic GUI widgets that are independent of the graphical user interface you are using, allowing you to write cross GUI figures and widgets. See `matplotlib.widgets` and the widget examples.

Slider Demo

## Fill demo

The `fill()` command lets you plot filled curves and polygons:

Fill

Thanks to Andrew Straw for adding this function.

## Date demo

You can plot timeseries data with major and minor ticks and custom tick formatters for both.

Date

See `matplotlib.ticker` and `matplotlib.dates` for details and usage.

## Log plots

The `semilogx()`, `semilogy()` and `loglog()` functions simplify the creation of logarithmic plots.

Log Demo

Thanks to Andrew Straw, Darren Dale and Gregory Lielens for contributions log-scaling infrastructure.

## Polar plots

The `polar()` command generates polar plots.

Polar Demo

## Legends

The `legend()` command automatically generates figure legends, with MATLAB-compatible legend placement commands.

Legend

Thanks to Charles Twardy for input on the legend command.

## Mathtext_examples

Below is a sampling of the many TeX expressions now supported by Matplotlib’s internal mathtext engine. The mathtext module provides TeX style mathematical expressions using FreeType and the DejaVu, BaKoMa computer modern, or STIX fonts. See the `matplotlib.mathtext` module for additional details.

Mathtext Examples

Matplotlib’s mathtext infrastructure is an independent implementation and does not require TeX or any external packages installed on your computer. See the tutorial at Writing mathematical expressions.

## Native TeX rendering

Although Matplotlib’s internal math rendering engine is quite powerful, sometimes you need TeX. Matplotlib supports external TeX rendering of strings with the usetex option.

Tex Demo

## EEG demo

You can embed Matplotlib into pygtk, wx, Tk, or Qt applications. Here is a screenshot of an EEG viewer called pbrain.

The lower axes uses `specgram()` to plot the spectrogram of one of the EEG channels.

For examples of how to embed Matplotlib in different toolkits, see:

## XKCD-style sketch plots

Matplotlib supports plotting in the style of `xkcd`.

Xkcd

    # An extra set of sample plots for the thumbnail image.
    import matplotlib.pyplot as plt
    import numpy as np

    np.random.seed(19680801)
    data = np.random.randn(2, 100)

    fig, axs = plt.subplots(2, 2, figsize=(5, 5))
    axs[0, 0].hist(data[0])
    axs[1, 0].scatter(data[0], data[1])
    axs[0, 1].plot(data[0], data[1])
    axs[1, 1].hist2d(data[0], data[1])

    plt.show()
