Obviously, different kinds of data require different kinds of plots. The X-Y plane is excellent for plotting relations between two different variables, an example from my work would be the total brightness of a galaxy versus its polarized intensity. Linestyle dash dot robots your data is just a pair of values for each point, a simple X-Y plane plot is perfect linestyle dash dot robots you! It is important to make sure that the two arrays you use for plotting have the same dimensions, or matplotlib will raise an exception when you try to plot them.
Now that I have matplotlib loaded, linestyle dash dot robots have some data to plot, I can start putting some code down for the figure. If I want to plot the radius of the circle on the horizontal axis, and the area on the vertical, I can simply use the following bit of code:. The final thing I need to do to actually have matplotlib display my figure is to use the show method from pyplot, which will pop up a nice interactive X11 window showing my figure. This is nice, it shows our data, but it is a bit spartan.
A figure without axis labels is useless to anyone other than the person who linestyle dash dot robots it. Our x-axis horizontal shows the radius of our circle, and the y-axis vertical shows the area. Our figure is going to look like this: We should start by defining another set of data for the area of the square:. We can then add a plotting command for the square.
Matplotlib offers a variety of options for color, linestyle, and marker. Here are a few of the linestyle dash dot robots common:. We should probably add a legend as well, to let the viewer know which curve is which. To do this, we can simply modify the two plot method calls by adding a label argument, and add a call to pyplot.
Once we do this, our plotting code will look like this:. Well, now you should be able to make some pretty looking plots of linear data! In the next installment, I will be showing you how to make another common type of plot: Feel free to leave me comments on what topics I should cover in future posts. Basic Data Plotting with Matplotlib Part 1: July 7, at 7: This actually makes me want to linestyle dash dot robots plots of nothing at all nothing at all, nothing at all.
That means this post was awesome! July 10, at Basic Data Plotting with Matplotlib Part 3: December 4, at 8: March 28, at 4: June 4, at 8: I arrived here hunting for just such a thing. Please keep up the great work. September 20, at 3: November 6, at 2: November 28, at February 1, at 1: Found this page through google.
I just finished my M. Good luck with your studies. March 10, at 7: Please …… I have a simple question! And if linestyle dash dot robots variables X, Y change over time? For example, data that are always updating matplotlib can plot?

We should start by defining another set of data for the area of the square: Here are a few of the most common: Once we do this, our plotting code will look like this: Multiple Plots Coming Soon Part 5: Very nicely written written post 2.
