Graph x-axis changes after changing from "today" to "yesterday" time range

I created a graph panel that shows the solar power creation of today which uses the time range “today” which is set on the overall dashboard time range settings. Now I would like to create the exact same panel that shows yesterdays values. I did this by copying the existing panel and by then entering "now-1d/d"in the query options in the new panel. However the new panel does not have the same x-axis as the old one / shows more hours of the day as the “today” panel.

Here is a link to a screenshot that shows the issue:
