SPANA: Diagram Window
The diagram window
It appears when SED/PREDOM finish a calculation. It is also created
when a diagram is selected in the main window, or double-clicked in the
File Manager / Explorer. Several diagram
windows may be displayed simultaneously.
When the plot-file is read, it is displayed with the options
(colours,
font, etc) selected in the menu
Preferences / Diagram windows
of the main window. After that, the diagram is kept in memory for faster update
when resizing, etc. If you make changes
manually to the plot file with a text editor, e.g. to add, delete,
or move labels, then you need to use the MENU /
Redraw (Ctrl-R)
in the diagram window to read the plot file again and to show the changes.
Displaying coordinates:
To read the coordinates of a point in a diagram, place the mouse on the point and
click on the right mouse button: a small window appears with the coordinates
at that point. For example, at what redox potentials is uranium insoluble
if pH = 7.5?
The figure shows that at EH
≤70 mV very little uranium is in solution
([U]TOT ≤10−7 M):
