![]() You also learned how to control these titles globally and how to reset values back to their default values. You also learned how to control the style, size, and position of these titles. In this tutorial, you learned how to use Matplotlib to add titles, subtitles, and axis labels to your plots. The method lets you pass in a string that represents the title that you want to apply. update() method again and pass in the default values: # Restoring rcParams back to default values Adding a title to a Matplotlib plot is done using the. In order to restore values to their default values, we can use the. Matplotlib stores the default values in the rcParamsDefault attribute. Once you’ve set the rcParams in Matplotlib, you may want to reset these styles in order to ensure that the next time you run your script that default values are applied. Resetting Matplotlib Title Styles to Default Values If you’re curious about the different rcParams that are available, you can print them using the () method. Plt.ylabel('y-Axis Title', style='italic', loc='bottom') Plt.xlabel('x-Axis Label', fontweight='bold') Let’s see how we can add and style axis labels in Matplotlib: # Adding Axis Labels to a Matplotlib Plot ylabel() adds an y-axis label to your plot xlabel() adds an x-axis label to your plot We can add axis titles using the following methods: This is part of the incredible flexibility that Matplotlib offers. Matplotlib handles the styling of axis labels in the same way that you learned above. Axis labels provide descriptive titles to your data to help your readers understand what your dad is communicating. In this section, you’ll learn how to add axis labels to your Matplotlib plot. In the next section, you’ll learn how to add and style axis labels in a Matplotlib plot. For the plotting I'm using pandas scatter plot for example: df.groupby('Column1').plot.scatter(x'Column2',y'Column3') Scatter plot return exactly 3 plot, but I want to know how to add chart title based on grouping from Column1 and also how to add the regression line. While this is an official way to add a subtitle to a Matplotlib plot, it does provide the option to visually represent a subtitle. Y = Īdding a subtitle to your Matplotlib plot Let’s see how we can use these parameters to style our plot: # Adding style to our plot's title The ones above represent the key parameters that we can use to control the styling. There are many, many more attributes that you can learn about in the official documentation. family= controls the font family of the font.fontweight= controls the the weight of the font.loc= controls the positioning of the text.fontsize= controls the size of the font and accepts an integer or a string. ![]() title() method in order to style our text: ![]() ![]() Let’s take a look at the parameters we can pass into the. Matplotlib provides you with incredible flexibility to style your plot’s title in terms of size, style, and positioning (and many more). Changing Font Sizes and Positioning in Matplotlib Titles This is what you’ll learn in the next section. We can easily control the font styling, sizing, and positioning using Matplotlib. Rotation of ticks ( check the label at x axis )ĭf.plot.scatter(title='rot=180',x='visit',y='sale') « Pandas plot plot.We can see that the title is applied with Matplotlib’s default values. We can specify log scaling or symlog scaling for x ( logx=True ) or log scaling for y ( logy=True ), we can specify both the axis by loglog ( loglog=True)ĭf.plot.scatter(loglog=True,x='visit',y='sale') rot We will show grid ( grid=True ) or not ( grid=False)ĭf.plot.scatter(title='grid=True',x='visit',y='sale',grid=True) logx logy loglog Here it is color=, this is in R G B format where each value varies from 0 to 1.ĭf.plot.scatter(title='Sale',x='visit',y='sale',color=) grid We can use one tuple to define the colours. ![]() We can use the option colors to give different colors to points. Here width is 6 inches and height is 3 inches.ĭf.plot.scatter(figsize=(6,3),x='visit',y='sale') fontsize fontsize=20, we can set the font size used labels in x and y axis.ĭf.plot.scatter(x='visit',y='sale',fontsize=20) Size of the graph, it is a tuple saying width and height in inches, figsize=(6,3). Title : title='sale Vs Visit' String used as Title of the graph. There are several options we can add to above scatter diagram. to generate scatter graph using dataĭf.plot.scatter(title='Sale Vs Visit',x='visit',y='sale') scatter chart with options Pandas DataFrame Plot scatter graph « Pandas plot ![]()
