When clicking the "Stacked" checkbox or the data series toggle buttons, the graph's x-axis is updated so that the right edge corresponds to the current time, but no new data is fetched, so a blank space can result at the right side of the graph. This is only obvious when the auto refresh option is disabled.
Test with payload 4.7.0-0.nightly-2021-01-31-031653 and chrome When clicking the "Stacked" checkbox, the issue is gone When click button 'Hide all Series', then click 'Show all Series', lastly click "Stacked" checkbox, the page will crash.
