Ensure new months pop up dynamically on Bar Chart

I have a stacked bar chart for each month since December '18. When I initially made this chart back in June, I had set my chart to show the months from Dec '18 to June '19. When the data for July started coming in, I wanted the July '19 bar to automatically pop up on the chart next to June’s bar, but it didn’t so I went in and manually changed the settings allowing for July’s data to show.
Is there a way I can now ensure that when August begins and August’s data comes in, a bar will pop up for August '19 on this chart? I don’t want to have to manually go in to all my charts at the beginning of every month and change the settings.
Thank you!

You could set your date filter to be ‘On or after’ 01-12-2018
