Main Graph Window 

 

The graph is an XY plot, with time plotted on the X-axis, oxygen plotted on the 

primary Y-axis (Y1) and pressure or temperature plotted on the secondary Y-axis 
(Y2).  The X-axis and the two Y-axes auto-scale during data logging so that all data 

points are shown on the graph.  You can select what is shown on the Y2 axis using 
the ‘View’, ‘Second axis display’ menu.

Plot Colours 

 

The default colours used on the graph are set to blue for oxygen and red for 
pressure r temperature.  To change the colours double-click on the coloured axis 

label at the top of each axis.  A colour palette window will appear and a new 
colour can either be chosen from a colour box, or for more variety, by clicking the 

‘Define Custom Colors >>’ button.  Click on ‘OK’ to select the new colour or 
‘Cancel’ to return to the graph without change.

Graph Titles and Labels 

 

If you want to change the text of the graph axis labels, place the mouse pointer 
over the text and do a single left click to enter edit mode.  The text can then be 

modified.  Similarly, to change the title of the graph, place the mouse pointer over 
the title and click once to edit.  If you choose not to enter a title the graph will 

display the path and filename of the run as the new title once the run has 
finished.  Note that these changes are only temporary and will be overwritten by 
the defaults if a new run is started or the graph window is closed and reopened.  

They are provided so that the plot may be printed with alternative labels.

Plot Co-ordinates 

 

The box labelled ‘Plot co-ordinates’ to the upper left of the graph window displays 
the actual plot co-ordinate value at the mouse pointer.  This can be used to get a 

quick oxygen value from the graph.  Simply place the mouse pointer at a place of
