There are several parameters that determine what the figure looks like: Argument Default Description num 1 number of figure figsize figure. MatPlotLib has various functions to acheive that. Hi, does anyone know of a way to create lines with variable thickness and color when doing a plot? Basically, I'd like to have a third dimension represented using thickness. In the code below we will suppose that we have only one line so that the list returned is of length 1. The most specific way, is to change the properties of a particular command: plt.

Microsoft R Visual Studio 2008. Figure can be thought of as a single container which contains all the objects representing axes, graphics, text, labels, etc. Drip drop A very simple rain effect can be obtained by having small growing rings randomly positioned over a figure. This is handy for fast plots. The function returns the current axes a instance , and returns the current figure instance. When we call plot, matplotlib calls gca to get the current axes and gca in turn calls gcf to get the current figure. When we set tick values, we can also provide a corresponding label in the second argument list.

We can have more control over the display using figure, subplot, and axes explicitly. But before you can use it, you should make sure it is installed. I've also found that the fivethirtyeight style changes the legend box in a way I can't revert, but using it with plt. Since python ranges start with 0, the default x vector has the same length as y but starts with 0. He currently works as an interdisciplinary research director at the University of Washington, conducts his own astronomy research, and spends time advising and consulting with local scientists from a wide range of fields. Am I missing a library? Q1 in our example plot , it uses the monospace font that was set earlier. We can make them bigger and we can also adjust their properties such that they'll be rendered on a semi-transparent white background.

In fact, all sequences are converted to numpy arrays internally. 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: plt. We will use a Gaussian centered about 2. Import pyplot module and alias it as plt. Hints You need to use the command.

Now that I have matplotlib loaded, and have some data to plot, I can start putting some code down for the figure. The black ones may be a bit surprising when one asked for a dotted grid. These are: Colour Code Colour Displayed R Red B Blue G Green C Cyan M Magneta Y Yellow K Black W White Marker Code Marker Displayed + Plus Sign. Perhaps a better solution is to allow keyword args to the plot command plot datar, -1. Once we do this, our plotting code will look like this: import matplotlib. Both can be useful depending on your intention.

Simple Line Plots with Matplotlib

Though there are several valid ways of using this, I find it easiest to specify the label of each line using the label keyword of the plot function: plt. When multiple lines are being shown within a single axes, it can be useful to create a plot legend that labels each line type. There are several parameters that determine what the figure looks like: Argument Default Description num 1 number of figure figsize figure. Major and minor ticks can be located and formatted independently from each other. LinearLocator Determine the tick locations.

If you provide a single list or array to the command, matplotlib assumes it is a sequence of y values, and automatically generates the x values for you. A common use for text is to annotate some feature of the plot, and the method provides helper functionality to make annotations easy. Tip Spines are the lines connecting the axis tick marks and noting the boundaries of the data area. I used the following code to generate the two attached images in v1. C is the cosine 256 values and S is the sine 256 values.

All of these locators derive from the base class matplotlib. It might be useful for the third argument to have color, style and width. This only requires adding the keyword argument label that will be used in the legend box to the plot commands. There are 21 styles in the Matplotlib 1. Microsoft R Visual Studio 2008.

Per default minor ticks are not shown, i. How can I use that to create lines with variable thickness? Of course, they won't grow forever since the wave is supposed to damp with time. It is with the plot function that we specify the line width of the plot. More information on specifying and formatting plot legends can be found in the plt. Major and minor ticks can be located and formatted independently from each other. Once we have created an axes, we can use the ax. I imported my mlab, and did dir mlab but that method doesn't show up in there.

Controlling a line pattern and thickness When creating figures for black and white documents, we are limited to gray levels. Microsoft R Visual Studio 2008. Hints You need to use Starting from the code below, try to reproduce the graphic on the right. It's possible to change these settings by specifying the font and text properties: the common aspects to define are the font type, weight, style, size and colour. In the latter case you could of course just loop over your properties.
