label - Available directly using geom_label() method.

bar - Available directly using geom_bar() method.

area - Available directly using geom_area() method.

line - Available directly using geom_line() method.

path - Available directly using geom_path() method.

points - Available directly using geom_points() method.The first parameter of the method is the geometric element name and then the parameters needed by that geometric element.īelow, we have listed some commonly used elements: The annotate() method let us add any type of geometric elements (plotnine methods starting with geom_) to chart.

At the end of arrows, we have also added animal names as text labels using annotate() method. Then, we have added four different types of arrows to chart using annotate() method. For simplicity, we have created chart with data from only 10 animals. The points are size-encoded by body weight and color-encoded by vore-type. In this section, we have explained how we can add arrow and text labels as annotations to our plotnine charts.įirst, we have created a scatter plot using "msleep" dataset showing relationship between body weight and sleep hours. Important Sections Of Tutorial ¶īelow, we have imported plotnine and printed version of it that we have used in our tutorial.

Plotnine: Quick Plots with One Line of Codeīelow, we have listed essential sections of tutorial to give an overview of the material covered.

If you are new to plotnine, we recommend you check the links below as it'll get you started with library faster. Tutorial explains different types of annotations like labels, arrows, slopes, bands, spans, polygons, boxes, etc.

What Can You Learn From This Article? ¶Īs a part of this tutorial, we have explained how to annotate charts created using Python library plotnine with simple and easy-to-understand examples. We can add annotations of different kinds like arrows and labels highlighting points, slope lines, polygons, vertical lines specifying spans, bands around lines, etc. It is generally referred to as annotation. We even highlight things like high few words with marker, draw round / square shapes around things, make acronyms, etc to remember things or to draw attention to an essential part of the article.
