If a backward incompatible change is introduced in one of the libraries, the conversion code might break and would need to be updated.Ĭheckout Cufflinks, a third-party library that adds an iplot() method to dataframes. Internal properties are subject to change.You could still customize hover labels, in any case, to show more information. If you create a chart using plotly.express, hover labels are automatically populated with useful information, which is one of the coolest features of Plotly. Hover labels show minimal information.Besides, I could not find a direct way to add a legend to a Plotly figure aside from adding traces with a name and show_legend=True. Therefore, to achieve a “true” grouped bar chart in Plotly, we must somehow infer grouping information from the Matplotlib plot. Unlike Plotly, though, bar grouping information is not stored explicitly under the hood in Matplotlib. If you create a grouped bar chart in Plotly using go or plotly.express, the grouping information is preserved. This can be easily seen by running a variety of plots through the conversion function and observing the output. ![]() While this approach works for a narrow range of plotting use cases, it is hacky and not suitable for a wider range of use cases. It takes a single argument of type AxesSubplot. Bar chart converterĪrmed with the understanding from the previous section, I wrote the following function to convert a given Matplotlib bar chart to a Plotly bar chart figure. Here onwards, we’ll refer to aph_objects as just go. Building a Matplotlib-to-Plotly converter Under the layout attribute, title, xaxis.title, and yaxis.title contain the plot title and axes titles. Plotly plot: Major death/capture events by year in Game of Thronesĭata is the attribute that contains almost all of the information required for the above plot. After a quick search, I found that AxesSubplot objects have a properties() method that returns their properties as a dictionary.įollowing is a bar chart from my Kaggle Notebook containing EDA on Game of Thrones battles and deaths data.īelow the chart is a snippet of its properties returned by ax.properties(). I started by examining ax, the AxesSubplot object returned by ot. E.g., data = df.groupby('year').sum()] ax = (rot=0) Matplotlib axes properties You simply call plot() on a dataframe, optionally specifying the plot kind, for an instant plot - no need to create an empty figure, set axis labels, legends, and so on. df.plot takes plotting to an even higher level of abstraction. The inner workings of both libraries are so well-abstracted that, for most common plotting purposes, we hardly ever need to tinker with the internals. The first step was to inspect how each of the libraries represented plots internally. Here is the full code if you would like to follow along as you progress through this article. Therefore, I decided to see if it was possible to convert a Matplotlib chart to its Plotly equivalent. However, Plotly isn’t currently supported. Since version 0.25, it also supports other backends such as Bokeh. Pandas currently uses Matplotlib as its default plotting backend. Have you ever wanted to directly create Plotly charts from a dataframe? Converting Matplotlib plots to Plotly plots Introduction ![]()
