I am working to analyze 4-5 physiologic signals recorded over several hours at 100 hz (a lot of data.) I need to display all the signals and scroll through them. I usually like to see 30 sec of data per page. I’m having a hard time deciding whether to use a 2-d diagram or a worksheet. I’ll present what I think are the advantages and disadvantages of each. I can code the missing features for each option, but I want to start off with the right decision:
Worksheet:
Advantage:
Scrolling features built in
Can activate the signal I am most interested in analyzingDisadvantage:
Can’t easily save a snapshot of the screen as a 2-d graph for presentation purposes (easiest to print it to a .PDF, but then limited ability to edit it after)
Changes made to one pane don’t reliable affect all panes – for example if I manually change the scaling of the x axis on the top pane, the other panes don’t change as well (even if zoom in sync is set)2-D Diagram:
Advantage:
All panes properly sync’d
Can easily save a snapshot for presentationDisadvantage:
No scrolling built in – would have to create macros to navigate through the signalAny suggestions?

Its purpose is to display multiple diagrams in one window and to synchronize the cursors between diagrams.
From the Automation point of view, a diagram and a worksheet are both “cursor objects”. In case of a worksheet, this object is managing the cusrors for up to 8 panes containing individual diagrams. In case of a diagram it is managing just its own cursors. If you use a worksheet, you can of course access each individual diagram within that.
Both alternatives do allow scrolling and zooming. In case of a diagram, the cursors must be enabled whereas in case of a worksheet the cursors are always enabled.
To syncronize zooming in a worksheet, you need to use the zoom between cursor function instead of manipulating the axis directly.
