Command to show more detail on the tactile display.
A tactile display has far fewer pins than a chart has pixels, so a whole plot
scaled onto it can collapse neighbouring marks into the same pin. Zooming
spends the same pins on a smaller slice of the chart, which is the only way
to tell those marks apart by touch.
