Sync Band Cursor in "Channel Table"

[Eric.Lu]

Hi,

I’m using diadem to playback my data, including “AI Signal”, “DI Signal”, “Serial Port Data”.

For “AI” and “DI” Signal I can choose the “Display Type-2D Axis System”.

For “Serial Port” the data is in string format, e.g. AA BB AC EF…… I choose “Display Type-Channel Table”

My question is when I use the band cursor to see the detail curve information in “2D Axis System” , all the numeric channel can Zoom in/off together,  while the “Serial Port” data is in the channel table, it’s not effected by the cursor, and I can’t get the exact/related "serial port data" in that time slot.

How can I sync the “Channel table” data with cursor?

Can I get the cursor start position and point it to the channel table, or make a SUDialog to display the data in band cursor range? 

My application is: 1) Review the AI/DI, Serial Data; 2)Select the interested data pieces; 3) Export the interested data files for report or sth else.

Thanks and waiting for reply.

Hi Xifeng,

There is no Automatic connection between the graph cursors and table rows in VIEW.  If you are using a "Curve Cursor" in the graph, such that the cursor always "snaps to" the curve, then you can right-click in the table and select the context menu "Goto >> Cursor Position".

If you want to process the X axis range on a variety of channels, then typically you would copy out those row ranges with the DataBlCopy() command.

Hi Brad,

Thanks for your advice, I have written a script to solve this problem.

1. I use the property “DisplayObj.XBegin” and “DisplayObj.Xend” in “2D Axis System” to get the relative time information in curve page.

Dim X1, X2

X1=view.Sheets(1).ActiveArea.DisplayObj.XBegin

X2=view.Sheets(1).ActiveArea.DisplayObj.XEnd

2. Write a small function to compare X1,X2 with the timestamp in “Serial Port” to allocate the relate data position, then set it as the active cell in “channel table”.

call view.Sheets(2).ActiveArea.DisplayObj.SetActiveCell(AllocatePos,1)

(AllocatePos is the relate data position that I calculated)

3. I customized the tool bar to add a new button, when users click this button, I will execute the script

Call MenuItemAdd("View","7","MenuItem","Sync time info","ScriptStart(""C:\Sync Analot time info to Serial Port.VBS"")")

The solution is kind of awkward, but it did work......

Thanks again, and sorry for my late reply.

Best rergards

Hi Guys,

You could retool this solution to use the VIEW-cursor-move event so that no button-click is needed, if you're interested.
