Is there a way to set the Y axis in a line chart to start from 0?

The Y axis seems to be dynamic and depends on the data. Is there a way to make it always start from 0 instead?

Yes, you can set the Y axis range (or the Y scale domain in D3 terms) for all XY components (Line, Area, Scatter, etc ...) by setting the yDomain property of XYContainer.

Here's an example in React:

<VisXYContainer yDomain={[0, undefined]} ...>
  <VisLine ... >
</VisXYContainer>

The yDomain value of [0, undefined] means that the lower limit will be 0 and the upper limit will be determined automatically based on the data.

You can read more about controlling the chart's scales in the documentation: https://unovis.dev/docs/xy-charts/Container#ydomain
