Hi  
I am using chart inside a report.  
My chart looks cramped (time axis compressed) on one report, but OK on another date selection.  
Any idea why it could be?  
Thanks  
Ravi

Is the data coming from a Tag History Data Source? It looks like [interpolation](https://docs.inductiveautomation.com/docs/8.1/ignition-modules/tag-historian/configuring-tag-history#seeded-values) is pulling in the last value from before your requested start time.

It may just be a coincidence that the second chart looks better, in that the timestamp of the last `Step No` change occurred closer to the requested start time.
