Dash Bootstrap Templates

Dash Bootstrap Templates

One of the cool features in the newly released Dash Labs is the option to generate Bootstrap themed figure templates at runtime when you use certain layout templates. It creates Plotly figure templates that have colorways, background colors and fonts based on your selected Bootstrap theme.

dash-bootstrap-templates is a new library of templates created based on the algorithms used in Dash Labs. It provides a template for each of the 22 Bootstrap/Bootswatch themes available in the Dash Bootstrap Components Library.

So, now you can use Bootstrap-themed Plotly figure templates in your current Dash apps by adding just 2 lines of code. :confetti_ball:

Give it a try!

pip install dash-bootstrap-templates

See the quickstart app below.

Demo Apps

In this app (code here), the graph on the left uses a Bootstrap figure template. The graph on the right uses the 'plotly' default figure template.
