How to change look and Feel of the Looker Dashboard

How to change look and feel of the dashboard, make it more appealing.?

Depends on what you don’t like; what is the problem you are trying to address?

Options include:

  • Global style: use themes to customise fonts and background colour etc.
  • Visualisations: use the Chart Config Editor to create new chart types, apply conditional formatting, add vertical reference bands, add annotations, add scrollbars, add tick marks to axes, customise tooltips and value labels etc. etc. - you can more or less achieve whatever you want.
  • Fields: use Liquid + HTML to add conditional formatting, images, emojis, and links to LookML fields.
  • Navigation: use tabs to break up the dashboard into more manageable chunks
  • Additional info: use markdown tiles + HTML to add menus, links, section headings, buttons, notes, responsive images.
  • Style Guide: write an internal style guide that details best practices for visualisations and dashboards. Save this as a Markdown file in the project. This ‘template’ ensures that all dashboards produced by your department look professional and are consistent i.e. business users know where to find things like global notes, and know how to interpret sequential / divergent colour palettes.

I would use all of the above.
