Related field suddenly showing up as a aggregate pie chart

[Tragertt]

I have a table that is referenced on my main table. It has always showed up as inline display of data suddenly it has now changed to a chart and looks like this

When you click on the pie chart it takes you to the data but why would it be displayed like this? I didnt change anything and all of a sudden it changed. Any ideas? This is on the main detail form

Maybe you inadvertently changed the inline view's type from Table to Chart. Regardless, you should be able to change the Chart view's type to Table instead.
