You can change the axis assignment, color, and line width of each PV. For the the axis assignments, the number in the "Axis" column identifies the Y-Axes via numbers 0, 1, 2, ... So to put PVs on the same, first axis, enter "0". To place them on two axes, enter "0" or "1" for the respective PV.
The "Min" and "Max" settings determine the Y-Axis range. The "Type" selects a linear or log. axis. Since these settings modify the Y-Axis, they percolate to all PVs which are on the same axis.

The "Re-scale for new archived data" selection determines how newly received archived data is handled:
For formulas, the formula is shown.
Change archive data sources
To add archive data sources, Drag-and-Drop an archive from the
Archive View
onto a PV. You can drop them onto the Plot Window,
which adds the source to all PVs in the plot,
or onto a selected PV in the config view.
Then, you can rearrange the order of
archives for a PV via the context menu
of the "Archives used for ..." table.
To delete an archive data source from a PV,
select the PV in the config view. Then, in the
"Archives used for ..." table, select the archive
data source to remove it via the context menu.
For a "scrolling" display, enter relative times that end in "now", for example a start specification of "-30 minutes" and an end of "now". Use the start/end time dialog, accessible via the "..." buttons, if the start/end time syntax is unclear.
