Graphing Preferences 
Before continuing you can select the variables you wish to view in the real-time display.  You can access 
this dialog in one of four ways: 
 
1.  Click Setup in the CIRAS main menu and open the Graphing – Preferences dialog box 
2.  Through the Graphing Options  button in the Setup dialog  
3.  Right-click anywhere on the Time or Data Plots using RCS from a computer 
4.  Click anywhere on the Time or Data Plots with the mousepad and pointer using the UI. 
 
Time Plot 
From the „Select Plot Type‟ list choose Time Plot.   
 
Select Variables 
Choose up to four variables to display as continuous colored plots in the Time Plot.  At least one variable 
must  be  displayed.    The  list  of  variables  automatically  changes  based  on  Accessories,  e.g.  variables 
related to chlorophyll fluorescence while using the CFM module.   
 
The available list is drawn from the parameters and variables seen in the Gas Exchange Measurement 
Screen section (page 26), with two exceptions – CO2 An. (Analysis gas CO
2
) and H2O An. (Analysis gas 
H
2
O). CO2 An. is simply CO2 Ref. + CO2 Diff.  Likewise, H2O An. is the H2O Ref. + the H2O Diff.   
 
Font Size 
Choose the font size that best meets your needs – larger fonts for computer RCS display, smaller for the 
UI when conducting research in the field.
