Purpose:

Highlight new X-Y Data

(Check box)

(Set via User Preferences)

Tick this check box if the latest data values should be highlighted on X-Y Graphs (both line and Scatter).  New data points are colored using the color assigned to the Y-pen, 'older' points use the X-pen colour.

Note:  The most recent point (singular) will also be circled in the Y-pen color.

Tip:  With earlier versions of Sapphire (pre 5.4) the circle used to highlight the latest data item used the X-pen colour.  To replicate this behaviour in release 5.4 onwards set the Y-pen colour to be the same as the X.

Highlight new X-Y Data

(Value box)

(Set via User Preferences)

This field controls the time period for which new data should be highlighted on X-Y Graphs.  The period is equal to the number set multiplied by the plots refresh rate.  So for a plot with a 5 second refresh rate, setting a value of 12 will mean that the most recent 1 minutes data is highlighted.  For a plot with 1 minute refresh rate, setting a value of 60 will mean the last hours data is highlighted and so on.  

Note:  Since the setting defines a time period and not the number of points to highlight, the 'amount' of pairs highlighted as new data will decrease once plot compression comes into effect when zooming out.  

Tip:  A plots refresh rate can be viewed on the Plot Properties Details tab in the Refresh Rate field when the Compression rate is 1:1 or lower (i.e. 1:n).
