It would be nice to have the ability to select a tool on a 1D (e.g., histogram) or 2D (e.g., x-y) plot that would allow the visualization and graphical setting of a selection region for filtering on the associated variable.

One possible realization would be as a pair of draggable vertical (or horizontal, for the y axis in a 2D plot) lines superposed on the plot. Small triangles / arrows attached to the lines could indicate the direction of the selection and allow "exclusive" selections (x not between 7 and 9) to be visualized.

It is basically visualize the filters. This ticket will capture the design and plan the scope. There will be several tickets to implement different scenario in the future.
