Search/Filter on toolbar applies to Charts

When the user free text searches or applies a data filter in
the top right toolbar search box it gets applied to any charts
that plot data from many rides, including;

- CP curve
- Calendar
- Histogram
- LTM
- TreeMap
- Summary

I need to update on a Mac to no longer use a Mac text search box
but now use a search filter box on the top right.
