Linking Plots Together

Learn how to link plots together.

Plots can be linked together to provide a wholesome experience. In cases where we have to compare plots, we can show multiple plots together in rows or columns to make comparison easy.

Consider this example: When showing different facets of the same data across different plots, linking plots together can help by using the same range for each of their axes.

Graphic shows linking plots example. There are 3 charts stacked on top of each other. They share the same x-axis. From left to right it reads: Jul 31, Aug 07, Aug 14, Aug 21, Aug 28. Chart 1: y-axis from bottom to top reads: 10, 20. There are three plot lines: Green, Blue and Red. Chart 2: y-axis from bottom to top reads: 0.0, 2.5, 5.0, 7.5, 10.0. There are three plot lines: Green, Blue and Red. Chart 3: y-axis from bottom to top reads: 0, 250, 500, 750. There are three plot lines: Green, Blue and Red.Click to enlarge

To link the plots, begin with a normal figure and then reference the linked figure ranges from the original to achieve multiple plots together.

In this step, we will link different plots together with the help of demonstration on Jupyter Notebook using Bokeh. We will use three figures for this demonstration.

Demonstration: Linking Plots Together

Step 1

Link the axes. The first two axes will have their x-axes linked, so panning one will update the x-axis of the other. The second two will be linked on y-axes, so panning one updates the y-axis of the other.


x = [1, 2, 3, 4]
y0 = [10, 8, 6, 2]
y1 = [2, 9, 4, 7]
y2 = [3, 6, 1, 5]

scatter_plot = figure(plot_width=figure_width, plot_height=figure_height)
scatter_plot.scatter(x, y0, color="red")


Step 2


Next, the second figure will be linked on the x-axis only. We supply the x_range keyword argument when creating the figure, passing in the first plot’s x_range attribute.




line_plot = figure(plot_width=figure_width, plot_height=figure_height, x_range=scatter_plot.x_range)
line_plot.line(x, y0, color="blue")


Step 3


Finally the third figure will link on the y-axis by sharing the y_range with the second figure:




circle_plot = figure(plot_width=figure_width, plot_height=figure_height, y_range=line_plot.y_range), y2, color="green", size=20)


Step 4


Now, plot the figures in a row.




show(row(scatter_plot, line_plot, circle_plot))


Screenshot from Jupyter Notebook that shows linking of multiple plots together. We see 3 different plot charts next to each other. The all have the same x-axis and y-axis formatting. The first has small plot points. The second is a line that connects those plot points. The third has 4 green dots. On the top right of each chart there is the edit section where their 4-way arrows are highlighted.Click to enlarge

What do You Observe?

Looking at the outputs, what do you think of the plot now? Is it much easier to understand the comparison among the three figures? Would you still prefer these plots shown as separate figures?
