Something went wrong with axis scaling

Error message

Something went wrong with axis scaling

What it means

Internal sanity check at the end of setConvert's axis preparation: after computing the linear-to-pixel transform (ax._m slope, ax._b offset, accounting for rangebreaks and log/date scales), the code verifies the transform is finite and the axis length is non-negative. The throw fires when the computed slope/offset are NaN or Infinity (e.g. a degenerate or invalid axis range such as [0, 0], Inf range endpoints, or corrupt rangebreaks), meaning pixel mapping is impossible.

Solutions

1. Inspect the axis range in layout (xaxis.range / yaxis.range) for NaN, Infinity, or identical endpoints and fix it.
2. Check rangebreaks bounds for invalid or reversed values.
3. Relayout with a valid explicit range, e.g. Plotly.relayout(gd, {'xaxis.range': [0, 10]}).
4. Report the trace/layout combination as a bug if the range was never set manually.
