Adaxial Stomata
Enter a known or estimated value of % upper leaf surface stomata for your leaf
sample. If you are unsure, it will help if you can determine if your leaf sample is
representative of a hypostomatous or amphistomatous plant species before
entering an estimate.
Settings Graph Set (F5)
The alternative to Numeric View is called
Graph View
. Configure Graph View in
Settings (F2)
>
Graph
Set (F5)
. In Graph View you can view up to 5 numeric variables and 3 graphs, using any combination of
measured and calculated data in the graphs. Select your desired set of variables from the Variable list,
Variable 1
through
Variable 5
. With the dropdown box highlighted, press
Expand List (F4)
to see a
section of the total list, or use the Up or Down arrows to move quickly through the list. The first variable in
the list is None. Choose None if you do not want numeric variables displayed or make a selection and
press
OK
. The graph or graphs that you choose to display can be customized in two basic ways: the
variables that will be shown and the numeric min-max scaling or time scale. Press the TAB key to move
down to
Graph1
.
Y Axis
is the first dropdown list containing all available variables. Again, with the
dropdown box highlighted, make your selection. Press TAB again to enter a value in the
Min
field, then
do the same for the
Max
field. Press
Change Sign (F3)
to enter a negative value after you make your
entry, usually in the
Min
field. Note that if you clear the field by pressing the DEL (delete) key the
selection defaults to Auto, which will auto-scale that entry.
X Axis
is the next dropdown list. The first variable that it contains is Time Span – choose this if you want
a single-variable plot, displayed over a period of between 2 and 60 minutes. Enter the time in the next
field,
Span
.
Min
and
Max
will be grayed out. Enter any variable except Time Span if you prefer a two-
variable scatter plot, then enter the
Min
and
Max
scales for that variable. The
Span
field will be grayed
out.
The first variable in the
Y Axis
list is None. Choose
None
if you do not want the graph displayed. For
example, if you set up
Graph1
as described above and select None for both Graph2 and Graph3, you will
see a single large graph. Select None for Graph3 to display two graphs only, etc.
