SECTION 7. PREFERENCES
7-6
Event Markers:
Specialized ID-2000 data files contain
“events” which can be displayed as
small rectangles on the data traces at
the location where the event occurred.
Figure 7-6 is an example of a file with
event markers.
File Name:
If this box is checked ID-2000 will
display the name of the file that is being
plotted at the lower left corner of the
plot. If multiple files are plotted ID-2000
will display “Multiple Files Plotted”.
Uncheck this box if you prefer not to
have the file name displayed.
Plot Note Outline:
If this box is checked ID-2000 draws a
box around each plot note. The color of
the box may be changed using the
Preferences - Colors tab. Changing the
setting of this feature affects all plot
notes. You may also change this
feature when editing or adding a plot
note in the Plot Note Text dialog.
Erase Plot Note Bgd:
If this box is checked ID-2000 erases
the graph underneath the plot note text.
You may turn this feature off if you do
not want the graph erased. Changing
the setting of this feature affects all plot
notes. You may also change this
feature when editing or adding a plot
note in the Plot Note Text dialog.
7.1.4 PERFORMANCE
This group contains two check boxes. The
“Calculate Data Statistics” box enables the
calculating of data statistics that can be
accessed via the View - Statistics menu item or
toolbar button. You can increase plotting
performance by unchecking this box so that ID-
2000 does not spend time keeping track of and
calculating statistics on the data that is plotted.
The second box is “Data Trace Update”. Any
time another window is displayed on top of the
ID-2000 application window, Windows sends a
command requesting that ID-2000 redraw its
window. If you are in the Plot view when this
occurs this would normally mean that ID-2000
would have to redraw the entire plot. Obviously
this would be inefficient especially if you are
plotting large data files that take significant time
to plot. Instead of redrawing the plot ID-2000
maintains an image of the plot in memory and
simply copies that image back to the display
screen.
