Update frequencies panel when data changes
Update frequencies panel when data changes

The frequencies component performed some basic comparisons between the previously rendered data and new data to avoid unnecessary re-renders. This logic was too simplistic and caused a bug where the component wouldn't re-render the graph when the data had indeed changed. This commit skips these checks. This may result in some unnecessary re-renders, however I couldn't find any in my testing.

Closes #1224
