If you label the columns and index of your DataFrame, pandas will automatically supply appropriate labels:. In this case, you'll still need to supply y-labels manually e. It is possible to set both labels together with axis. Look for the example:. Thus to set the x label you will need to do something like this.

Python had been killed by the god Apollo at Delphi. Python was created out of the slime and mud left after the great flood. The programming language Python has not been created out of slime and mud but out of the programming language ABC. It has been devised by a Dutch programmer, named Guido van Rossum, in Amsterdam.

Origins of Python Guido van Rossum wrote the following about the origins of Python in a foreword for the book "Programming Python" by Mark Lutz in "Over six years ago, in DecemberI was looking for a "hobby" programming project that would keep me occupied during the week around Christmas. My office a government-run research lab in Amsterdam would be closed, but I had a home computer, and not much else on my hands.

I chose Python as a working title for the project, being in a slightly irreverent mood and a big fan of Monty Python's Flying Circus.

We have to learn to live with it. It is seldom a good idea to present your scientific or business data solely in rows and columns of numbers.

We rather use various kinds of diagrams to visualize our data. This makes the communication of information more efficiently and easy to grasp.

In other words, it makes complex data more accessible and understandable. The numerical data can be graphically encoded with line charts, bar charts, pie charts, histograms, scatterplots and others. We have already seen the powerful capabilities of for creating publication-quality plots.

Matplotlib is a low-level tool to achieve this goal, because you have to construe your plots by adding up basic components, like legends, tick labels, contours and so on. Pandas provides various plotting possibilities, which make like a lot easier. You can see a simple example of a line plot with for a Series object. We use a simple Python list "data" as the data for the range. The index will be used for the x values, or the domain. In our example this will give us the same result:.

We will introduce now the plot method of a DataFrame. We define a dcitionary with the population and area figures. This dictionary can be used to create the DataFrame, which we want to use for plotting:. We will multiply the area column bybecause otherwise the "area" line would not be visible or in other words would be overlapping with the x axis:.

This plot is not coming up to our expectations, because not all the city names appear on the x axis.Scatter plots are used to depict a relationship between two variables. For example, I collected the following data that captures the relationship between two variables related to an economy:. Once you have your data ready, you can proceed to create the DataFrame in Python. For our example, the DataFrame would look like this:. Line charts are often used to display trends overtime.

Here, I compiled the following data, which captures the unemployment rate over time:. Bar charts are used to display categorical data. The goal is to create a pie chart based on the above data. You just reviewed few examples about plotting DataFrames using pandas. A good additional source for plotting DataFrames is the pandas documentation.

For example, I collected the following data that captures the relationship between two variables related to an economy: Step 2: Create the DataFrame Once you have your data ready, you can proceed to create the DataFrame in Python.
