Bokeh supports many plotting tools, but I introduce HoverTool here because it's particularly useful for data exploration and interaction. HoverTool allows you to set a tooltips property which takes a list of tuples. The first part of the tuple is a display name and the second is a column name from your ColumnDataSource prefaced with @ Bokeh integrates the NetworkX package so you can quickly plot network graphs. The bokeh.plotting.from_networkx convenience method accepts a networkx.Graph object and a NetworkX layout method and returns a configured instance of the GraphRenderer model. Here is how the networkx.spring_layout method lays out the Zachary's karate club graph. 00:00 So, what if you'd like to see a little more information about the glyphs that you've selected? You can do that by adding hover actions using Bokeh's HoverTool.You'll add this functionality to the script you just completed, the ThreePointAttVsPct.Make a copy. 00:17 and rename it with the word Hover at the end, so ThreePointsAttVsPctHover.. 00:24 What needs to be added the bokeh HoverTool: we'll need it to change the format of the tooltip from bokeh.models import ColumnDataSource, HoverTool import pandas as pd. Then, we create the dataframe from our sample, and we print the first rows: df = pd.DataFrame(sample, columns=('x','y')) df.head( The tool that shows information from the plot objects is an inspector called HoverTool that annotate or otherwise report information about the plot, based on the current cursor position. Let's see now how this can be done. First we need to import the HoverTool from bokeh.models that includes

If you are looking to create powerful data visualizations then you should consider using Bokeh. In an earlier article, How to Create an Interactive Geographic Map Using Python and Bokeh, I demonstrated how to create an interactive geographic map using Bokeh.This article will take it a step further and demonstrate how to use an interactive map with a data table and text fields organized. Pandas Bokeh is supported on Python 2.7, as well as Python 3.6 and above. How To Use. The Pandas-Bokeh library should be imported after Pandas. After the import, one should define the plotting output, which can be: pandas_bokeh.output_notebook(): Embeds the Plots in the cell outputs of the notebook. Ideal when working in Jupyter Notebooks Thanks to Bokeh's HTML output, you get the full interactive experience when you embed the plot in a web app. You can copy this example as an Anvil app here (Note: Anvil requires registration to use).. Now you can see the reason for the extra effort of wrapping all your data in Bokeh in objects such as ColumnDataSource.In return, you can add interactivity with relative ease I have been wanting to build a simple web app with some interactivety for a while now. I used a few different tutorials/demos to build this kind of app. Specifically, I used Bokeh, an interactive Javascript based visualization library, and Flask to build a web app and then deploy it to Heroku, a cloud platform for web apps (and more)

One issue we faced now is when there are multiple lines especially when they are close to each other, hover tool showing as labels would make this even more crowded

The HoverTool has a callback which comes with two pieces of built-in data: the index and the geometry. The index is the indices of any points that the hover. The HoverTool tooltips argument is a list of tuples - one tuple for each dimension of the data. The first argument of the tuple (e.g. month) is the label that will appear when the user hover's over the data point, while the second (e.g. @month_label) tells bokeh which column to use for the data (so it has to match the key you used in the. HoverTool is used to display the data when we hover the mouse pointer over the points of the plot and ColumnDataSource is the Bokeh version of DataFrame. We will discuss more on it later. We will.

Using the bokeh.plotting interface, we can also specify which tools we want available. For example, we can add a HoverTool that will give information about each data point if we hover the mouse over it. Let's add it to the ECDF so we can look up the exact values of $\tau$ and $\hat{F}(\tau)$ In the hover tool definition a few changes are important: In the toot tip section it is important to point ot the correct formatter followed by {custom} , e.g. '@freq {custom}'. The formatter name should match the variable name and now has @ before its name, e.g. '@freq'. The formatter now points to a custom python function the user creates, e. from bokeh.sampledata.iris import flowers from bokeh.plotting import figure from bokeh.io import output_file, output_notebook, show from bokeh.models import ColumnDataSource In [3]: output_notebook (
