Instead of manually scaling the charts, you can set up the Auto Scale feature. This will scale the charts to have all bars in the current frame adjust as you zoom in and out of a chart.
There are some limitations to doing this. For example, you can scroll horizontally but you are unable to scroll vertically. If you want to scale the chart vertically you will to turn off the auto scaling button.
To toggle Auto Scale you can utilize the shortcut button in the below image:
Or right click on the chart and go to Chart Settings > Scaling.
Click on the "Scaling" tab
Once done, click OK or Apply to update the chart settings.
