[Python] Visualizing data

In Python there are a few ways to visualize data ...

... and i want to show you a very simple one here:

We are going to use "Matplotlib" for that.

"Matplotlib" is a python module, what makes it realy easy to draw diagrams.

The input data can come from a csv file or any other file.

To draw the diagram from above, i have written the following code:

1 2 3 4 5 6 7

import matplotlib.pyplot as plt year = [2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012] jackpot_hits = [4, 7 ,4, 3, 8, 5, 2, 1, 3, 7, 4, 3, 9] plt.plot(year, jackpot_hits) plt.show()

Does not seem to be very hard, right?

So what do we do here?

import matplotlib.pyplot as plt

Here we import the needed module to be able to draw diagrams.

year = [2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012]
jackpot_hits = [4, 7 ,4, 3, 8, 5, 2, 1, 3, 7, 4, 3, 9]

Then we create two lists: "year" and "jackpot_hits".

plt.plot(year, jackpot_hits)

Here we create the diagram with the function "plot()", based of the data within the lists. "year" is the diagram's x-axis (horizontal) and "jackpot_hits" the y-axis (vertical).

plt.show()

And finally the function "show()" draws the diagram.


And thats it, as easy as that. :)
