Is there any way to add a Matplotlib visualizaton to a notebook Dashboard?

So I love that databricks lets you display a dataframe, create a visualization of it, then add that visualization to notebook dashboard to present. However, the visualizations lack some customization that I would like. For example the heat map visualization from the notebook dashboard doesn't let you modify the min max values for the color bar.

I have a matplotlib heatmap that is much more customized. Is there anyway to add this matplotlib visualization to a notebook dashboard?

What you can do is run the visualization in the notebook, save it as image and display it in the dashboard, for example:

import matplotlib.pyplot as plt import seaborn as sns import numpy as np # Sample data data = np.random.rand(10, 12) heatmap = sns.heatmap(data, cmap='viridis') plt.show()

heatmap.figure.savefig('/dbfs/tmp/heatmap.png')

displayHTML('<img src="/files/tmp/heatmap.png" alt="heatmap">')

I see what you're saying but what if I want a set up where a user can enter parameters into widgets and the corresponding heat map updates? With the method you suggested, it will just be a static heat map until I rerun the notebook,correct?

This is correct, it seems the way you want to implement is not currently supported
