Suppose you run Graph Builder and choose a Column with 200 unique values for the x axis.
You may find some values of this Column irrelevant and feel like filtering data by this Column.
Currently, (in JMP 14), you will need to click the Red Triangle, add a Local Data Filter, and choose the same Column from the list.
It will be handy if a Column can be added to a Local Data Filter by clicking an axis, etc. It will be even nicer if values of a Column can be chosen directly on an axis and hidden.
