Graph Screen

The functions of the tags at the top of the screen are the same as on the 'Table Screen'.

The results are displayed as a graph of either absorbance or transmittance, with time in seconds as the default setting of the x-axis.

The graph scales automatically as the data accumulate.

The x-axis can be changed to show some other value, eg concentration, by using the 'Note' box.
Enter the numerical value you want for the x-axis in the note box and tap 'Separate Event'. If you repeat this for several different concentrations the x-axis will show the numbers entered instead of time.
This works if each separate event is associated with a number only - see the video clip.

Tapping any of the points on the graph highlights it. Once two or more points are tapped the 'Best Fit Line' is drawn through the highlit ponts and the equation for the line displayed in the form,

y = ax + b

where a is the slope of the line and b is the intercept on the y-axis.

Use the Save and Sessions tags to save and recall data (See the Save Results option on the menu.)
