You can’t use different X-axis scales for different metrics in a single Mixpanel report; the X‑axis (time or property buckets) is shared across all metrics in that chart.
What you can customize per metric is the Y‑axis:
- Go to the Chart tab → Axis settings.
- Assign each metric to Left or Right Y‑axis (Axis Assignment). [Chart customization]
- Configure each Y‑axis separately (label, unit, min/max, decimals, linear/log scale). [Chart customization]
The knowledge sources do not mention any way to have multiple or independent X‑axes within one report.
