Seaborn comes with a number of customized themes and a high-level interface for controlling the look of matplotlib figures. Note that in versions of seaborn prior to 0. On later versions, it must be explicitly invoked. Seaborn splits matplotlib parameters into two independent groups. The first group sets the aesthetic style of the plot, and the second scales various elements of the figure so that it can be easily incorporated into different contexts.
The interface for manipulating these parameters are two pairs of functions. In both cases, the first function returns a dictionary of parameters and the second sets the matplotlib defaults. There are five preset seaborn themes: darkgridwhitegriddarkwhiteand ticks.
They are each suited to different applications and personal preferences. The default theme is darkgrid. As mentioned above, the grid helps the plot serve as a lookup table for quantitative information, and the white-on grey helps to keep the grid from competing with lines that represent data. The whitegrid theme is similar, but it is better suited to plots with heavy data elements:.
For many plots, especially for settings like talks, where you primarily want to use figures to provide impressions of patterns in the datathe grid is less necessary. Sometimes you might want to give a little extra structure to the plots, which is where ticks come in handy:. Both the white and ticks styles can benefit from removing the top and right axes spines, which are not needed. The seaborn function despine can be called to remove them:. Some plots benefit from offsetting the spines away from the data, which can also be done when calling despine.Introduction to Seaborn - How seaborn Python works with matplotlib along with seaborn and pandas
You can also control which spines are removed with additional arguments to despine :. This also allows you to make figures with differently-styled axes:.
Note that you can only override the parameters that are part of the style definition through this method. If you want to see what parameters are included, you can just call the function with no arguments, which will return the current settings:. A separate set of parameters control the scale of plot elements, which should let you use the same code to make plots that are suited for use in settings where larger or smaller plots are appropriate.
The four preset contexts, in order of relative size, are papernotebooktalkand poster. The notebook style is the default, and was used in the plots above. You can also independently scale the size of the font elements when changing the context.
This option is also available through the top-level set function. Similarly, you can temporarily control the scale of figures nested under a with statement. Both the style and the context can be quickly configured with the set function. This function also sets the default color palette, but that will be covered in more detail in the next section of the tutorial. The whitegrid theme is similar, but it is better suited to plots with heavy data elements: sns.
How to set the size of a figure in matplotlib and seaborn
The seaborn function despine can be called to remove them: sinplot sns. If you want to see what parameters are included, you can just call the function with no arguments, which will return the current settings: sns.In this short tutorial, we will learn how to change Seaborn plot size.
For many reasons, we may need to either increase the size or decrease the size, of our plots created with Seaborn. For example, if we are planning on presenting the data on a conference poster, we may want to increase the size of the plot. Now, if we only to increase Seaborn plot size we can use matplotlib and pyplot.
One example, for instance, when we might want to change the size of a plot could be when we are going to communicate the results from our data analysis. In this case, we may compile the descriptive statistics, data visualization, and results from data analysis into a report, or manuscript for scientific publication. Here, we may need to change the size so it fits the way we want to communicate our results. Note, for scientific publication or printing, in general we may want to also save the figures as high-resolution images.
First, before learning how to install Seabornwe are briefly going to discuss what this Python package is. This Python package is, obviously, a package for data visualization in Python. Furthermore, it is based on matplotlib and provides us with a high-level interface for creating beautiful and informative statistical graphics. It is easier to use compared to Matplotlib and, using Seaborn, we can create a number of commonly used data visualizations in Python.
Now, whether you want to increase, or decrease, the figure size in Seaborn you can use matplotlib. Note, this code needs to be put above where you create the Seaborn plot. Now, if we want to install python packages we can use both conda and pip. Conda is the package manager for the Anaconda Python distribution and pip is a package manager that comes with the installation of Python.
In this section, we are going to learn several methods for changing the size of plots created with Seaborn.
First, we need to install the Python packages needed. Second, we are going to create a couple of different plots e. Finally, when we have our different plots we are going to learn how to increase, and decrease, the size of the plot and then save it to high-resolution images.
First, however, we need some data. Conveniently, Seaborn has some example datasets that we can use when plotting.
In the code chunk above, we first import seaborn as sns, we load the dataset, and, finally, we print the first five rows of the dataframe. Now that we have our data to plot using Python, we can go one and create a scatter plot:.Setting figure sizes, like rotating axis tick labelsis one of those things that feels like it should be very straightforward.
However, it still manages to show up on the first page of stackoverflow questions for both matplotlib and seaborn. Part of the confusion arises because there are so many ways to do the same thing - this highly upvoted question has six suggested solutions:. Let's jump in. As an example we'll use the olympic medal dataset, which we can load directly from a URL For our first figure, we'll count how many medals have been won in total by each country, then take the top thirty:.
Ignoring other asthetic aspects of the plot, it's obvious that we need to change the size - or rather the shape. Part of the confusion over sizes in plotting is that sometimes we need to just make the chart bigger or smallerand sometimes we need to make it thinner or fatter. If we just scaled up this plot so that it was big enough to read the names on the vertical axis, then it would also be very wide.
We can set the size by adding a figsize keyword argument to our pandas plot function. The value has to be a tuple of sizes - it's actually the horizontal and vertical size in inches, but for most purposes we can think of them as arbirary units.
And here's a version that keeps the large vertical size but shrinks the chart horizontally so it doesn't take up so much space:. OK, but what if we aren't using pandas' convenient plot method but drawing the chart using matplotlib directly? Let's look at the number of medals awarded in each year:. This time, we'll say that we want to make the plot longer in the horizontal direction, to better see the pattern over time.
If we search the documentation for the matplotlib plot funtion, we won't find any mention of size or shape. This actually makes sense in the design of matplotlib - plots don't really have a size, figures do. So to change it we have to call the figure function:.
Notice that with the figure function we have to call it before we make the call to plototherwise it won't take effect:. OK, now what if we're using seaborn rather than matplotlib? Well, happily the same technique will work. We know from our first plot which countries have won the most medals overall, but now let's look at how this varies by year. We'll create a summary table to show the number of medals per year for all countries that have won at least medals total. Now we come to the final complication; let's say we want to look at the distributions of the different medal types separately.

In addition to elz answer regarding "figure level" methods that return multi-plot grid objects it is possible to set the figure height and width explicitly that is without using aspect ratio using the following approach:.
Just after the plot with seaborn so no need to pass an ax to seaborn or to change the rc settings.

Note that their use is deprecated, and maintained only for backwards compatibility. For example, to create a new evaluation named "my evaluation" using the first 50 instances in the dataset.
Once an evaluation has been successfully created it will have the following properties. That is, each measure is computed with respect to each class, then the computed values are averaged to get the average measure. You can read more on macro vs. The full set of matrices is used to construct the rest of the measures.
The first threshold is always nil, indicating the case where everything is classified positively. Ranking Measures measure the quality of the ranking provided by the classifier, as estimated from the performance at different operating thresholds.
The canonical curve of this sort is the ROC curve, which shows the false positive rate and the recall at each threshold. Note that the last threshold is nil, indicating the case where every is classified positively (the curve thresholds are sorted in the opposite order from the list of confusion matrices to maintain a non-decreasing ordering for the x-axis values of the curves).
A detailed result object for regression models has the following properties: Time series evaluations compare time series predictions (forecasts) against a test dataset containing true future time series values. For each field in the test dataset corresponding to the objective fields in the time series model, BigML computes the point predictions using each of the field's ets models (including the trivial ets models), with a forecast horizon equal to the number of rows in the test dataset.
A result object for time series models has the following properties: A detailed result object for time series models has the following properties: Creating an evaluation is a process that can take just a few seconds or a few days depending on the size of the dataset used as input and on the workload of BigML's systems. The evaluation goes through a number of states until its fully completed.
Through the status field in the evaluation you can determine when the evaluation has been fully processed. Once you delete an evaluation, it is permanently deleted.
If you try to delete an evaluation a second time, or an evaluation that does not exist, you will receive a "404 not found" response. However, if you try to delete an evaluation that is being used at the moment, then BigML. To list all the evaluations, you can use the evaluation base URL. By default, only the 20 most recent evaluations will be returned. You can get your list of evaluations directly in your browser using your own username and API key with the following links.
You can also paginate, filter, and order your evaluations. It is intended as an import for executable scripts. You can read the WhizzML Reference Manual for more information.

Earnhardt is favored to win the event, according to OddsShark. Chase Elliott and Earnhardt will start in the front row, and both men will have to be concerned with Busch, Hamlin, Jamie McMurray, Kevin Harvick and Clint Bowyer.
Earnhardt said on media day that he is close to retirement from racing. He said the reason he has returned is a chance to win the championship. I would be out of here. Coming back from this injury, we worked so hard. To come back this year, win a championship, it would be hard not to hang it up.
The Great American Race is always about much more than horsepower and drafting. It is about being aggressive at the right time and taking advantage of the small holes that other drivers leave. The driver who does this bestand has no mishap with any aspect of the carhas the best chance to win.
Everyone has to shake off the rust at Daytona, and Earnhardt has more of it than most of his competitors. That's why we like Keselowski to emerge here and take the checkered flag. He can bide his time and should have an excellent chance to run the favorite down and capture the title. He will face challenges from Logan, Elliott and Harvick, but this should be Keselowski's race to win. Jamie McMurrayChip Ganassi Racing4. Denny HamlinJoe Gibbs Racing5.
