\documentclass{standalone} \usepackage{pgfplots} \begin{document} \begin{ tikzpicture} \begin{axis}[] \addplot[mark=none, domain= 1], Output [., 3 ], lty=2) # Plot heritabilities on generation ymin -- min (Output [. ylim-c (ymin, ymax)) lines (Output [., 1], Output [., 7], lty=2) # Plot correlations. Recent Matplotlib versions make it relatively easy to set new global plotting .. by passing a list that specifies [xmin, xmax, ymin, ymax] (Figure ): But visualizing relationships in such high-dimensional spaces can be extremely difficult.

So, for example, you may have a file called myplot. The details of this operation can vary greatly from system to system and even installation to installation, but Matplotlib does its best to hide all these details from you. One thing to be aware of: Multiple show commands can lead to unpredictable backend-dependent behavior, and should mostly be avoided.

Excel: Scatterplot and correlation

IPython is built to work well with Matplotlib if you specify Matplotlib mode. Some changes such as modifying properties of lines that are already drawn will not draw automatically; to force an update, use plt. In the IPython notebook, you also have the option of embedding graphics directly in the notebook, with two possible options: Basic plotting example Saving Figures to File One nice feature of Matplotlib is the ability to save figures in a wide variety of formats.

Basic Plots

You can save a figure using the savefig command. For example, to save the previous figure as a PNG file, you can run this: PNG rendering of the basic plot In savefigthe file format is inferred from the extension of the given filename. Depending on what backends you have installed, many different file formats are available. You can find the list of supported file types for your system by using the following method of the figure canvas object: Two Interfaces for the Price of One A potentially confusing feature of Matplotlib is its dual interfaces: You can get a reference to these using the plt.

While this stateful interface is fast and convenient for simple plots, it is easy to run into problems. For example, once the second panel is created, how can we go back and add something to the first? Fortunately, there is a better way.

Object-oriented interface The object-oriented interface is available for these more complicated situations, and for when you want more control over your figure. Subplots using the object-oriented interface For more simple plots, the choice of which style to use is largely a matter of preference, but the object-oriented approach can become a necessity as plots become more complicated. Throughout this chapter, we will switch between the MATLAB-style and object-oriented interfaces, depending on what is most convenient.

In most cases, the difference is as small as switching plt. Simple Line Plots Perhaps the simplest of all plots is the visualization of a single function. Here we will take a first look at creating a simple plot of this type. An empty gridded axes In Matplotlib, the figure an instance of the class plt. Figure can be thought of as a single container that contains all the objects representing axes, graphics, text, and labels.

The axes an instance of the class plt. Axes is what we see above: Once we have created an axes, we can use the ax.

Line Colors and Styles The first adjustment you might wish to make to a plot is to control the line colors and styles. To adjust the color, you can use the color keyword, which accepts a string argument representing virtually any imaginable color. Plotting a histogram gives a sense of the range, center, and shape of the data. It shows if the data is symmetric, skewed, bimodal, or uniform. Box plots and plots of means, medians, and measures of variation visually indicate the difference in means or medians among groups.

Scatter plots show the relationship between two measured variables. Communicate your results to others. Being able to choose and produce appropriate plots is important for summarizing your data for professional or extension presentations and journal articles.

Plots can be very effective for summarizing data in a visual manner and can show statistical results with impact. It is essential to understand the plots you find in extension and professional literature.

As McDonald notes, one way is to have a cluttered or unclear plot, and another is to use color inappropriately. I strive for clear, bold text, lines and points. In a presentation, it can be difficult for the audience to understand busy plots, or see thin text, lines, or subtle distinctions of colors. Publications may or may not accept color in plots, and subtle shading or hatching may not be preserved. Sometimes the resolution of images of plots are downsampled, making small text or symbols unclear.

In general, a plot and its caption should more-or-less be able to stand alone. Be sure to label axes as thoroughly as possible, and also accurately.

When possible, plots should show some measures of variation, such as standard deviation, standard error of the mean, or confidence interval.

By their nature, histograms and box plots show the variation in the data. Plots of means or medians will need to have error bars added to show dispersion or confidence limits. If applicable, usually the x-axis is the independent variable and the y-axis is the dependent variable of an analysis.
