Hi team,
If you’ve built custom charts in Holistics, you know the friction: define the template in Admin Settings, switch to Explore to preview, and repeat. There’s no version history, syntax validation, or dependency checking.
This new update is for you!
What’s new
Custom charts now live in AML. With this update, you can define them as code, create them through a GUI, and preview against real data:
- Define as code: Create a
CustomChartblock in a.chart.amlfile. Charts are version-controlled in Git, syntax-validated, with dependency checks that prevent accidental deletion. - Easy creation flow: Get started quickly using any of these three paths:
- Chat with AI: Describe what you want, attach files (images, PDFs, etc.), or tag in-app context (datasets, dashboards, files) so AI has full context to generate your chart code.
- Pick a template: Start with a pre-built chart layout and customize it to fit your data.
- Build from scratch: Start from blank and write your custom code from the ground up.
- Preview while editing: As you write chart code, a preview panel renders the chart against real data. This lets you see and debug the output without leaving the editor.
Legacy migration
Legacy (non-as-code) custom charts still work as normal. Their definitions in Admin settings remain accessible for viewing, editing, and deletion, but all new charts must be defined as code.
We provide a path to generate the as code version of the legacy chart in the Admin settings > Custom charts > Copy to Development.
