I use OriginPro7 as a graphic server for data acquisition. A sample of data is sent Origin every 50 millisecond in a worksheet, the histogram of the sample is calculated into a second worksheet to which corresponds a XY bars graph. Finally, the first worksheet is cleared with the command clearworksheet (because the size of the samples is not constant).
1) How to inhibit the automatic refreshement of the graph due to the command clearworksheet ? (the frequency is to high, that is not so nice for eyes !!!)
2) what is the best way to update the graph ? For example I would like to refresh only the layer or the curve without refreshing all the objects of the page (buttons, text, and so on)
have you any suggestion?
thanks,
Isabelle COMPAGNON

Dear Mike
the command "set wksname -er xx" semms to work very well.
For the graph I have found the command "plot -c" wich refresh the data whitout changing the scale.
Thank you very much for your help !

Hi Isabelle,
1) The clearworksheet macro does more than is probably necessary to reset your worksheet. Try using this command instead...
set wksname -er 30; // set wks to 30 rows (if there is a minimum number of samples you could use that number instead of 30)
2) You'll probably need to rescale from time to time anyway (especially if your sample size is changing) so you might use the rescale command to update the graph...
layer -a; // rescale to show all
...You might find it unnecessary to update the graph at all. Changes in the histogram data should show up automatically.
