In the plot (which is a cumulative distribution function, if that matters), the colors differentiate data relevant to different days; the markers are used to further differentiate the data within each day. Here we will use two lists as data with two dimensions (x and y) and at last plot the lines as different dimensions and functions over the same data. How to Change Legend Font Size in Matplotlib?

Why is "1000000000000000 in range(1000000000000001)" so fast in Python 3? You can see that the Area line is not showing any identical trend with the data as the scale of the Area is very small comparatively from the Population Density. You can limit the y axis with plt.ylim(0.25,1) but the previous might look more appealing. We've also changed the tick label colors to match the color of the line plots themselves, otherwise, it'd be hard to distinguish which line is on which scale. The best answers are voted up and rise to the top, Not the answer you're looking for? Download Python source code: multicolored_line.py, Download Jupyter notebook: multicolored_line.ipynb. Find centralized, trusted content and collaborate around the technologies you use most. The problem with this solution is that I find it not immediate to automate, at least not by using the cycler as shown above. To understand the concept more clearly, lets see different examples: In this example, we draw three multiple lines plots. Difficulties with estimation of epsilon-delta limit proof. Use pandas.DataFrame.plot to plot. The problem is that the plot is very crowded and a bit ugly. Lets see examples of a subplot having multiple lines: In the above example, we use the subplot() function to create subplots. Question: Any idea how I can better plot this data? into the default property cycle. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2. Another simple way is to use the pandas.DataFrame.pivot function to format the data. From simple to complex visualizations, it's the go-to library for most. In this example, well use the array() function of numpy to plot multiple lines with different lengths. Have a look at the colormaps here (gist_ncar is about 2/3 of the way down): http://matplotlib.org/examples/color/colormaps_reference.html.
