While dragging it with the mouse the time and y-value of the cursor position are displayed above the graph. By clicking with the middle mouse button in the graph window, a pop up window will display a listing of all time series traces shown for the graph. This allows you to switch between traces available on the graph. The graph will show the PE, TS, and E and if D is something other than 0 then it will be shown. If the time series is a forecast trace, then the basis time is shown.
Current time is shown on the plot as a double-width dashed vertical line.
When the window is resized the graph adjusts.
