Once again, I will need your expertise to resolve a pertinent issue. It seems that a bug is happening when publishing my report to the service. As you can see below, I have a chart that goes from 2015/to date and shows a trend on line and volumes on bars.
Issue is that, when published it gets all over and the visualization isn't as the one that was saved in the Power BI desktop.
I cannot reproduce the same issue.I would suggest you use latest version of Power BI Desktop and test again.Do you use RSL for the data?Do you have access to view the data in power bi service?It would be better if you could share the .pbix for us to test.If it is not your case,you may submit a support ticket.
