Time dependent charts are either available from most of the entry forms with time dependent data or directly from the main menu.
The Quick Chart buttons on the entry forms allow only one chart (Top Chart) with one (left) Y-axis for the value of the time dependent parameter. Several settings for the chart can be set in the “Time dependent Chart Settings” (see Help sub-item below). Accessing time dependent charts from the main menu, however, allows selecting 4 different Y-axis parameters for top and bottom charts (which are time-synchronised).
