luke Posted October 1, 2011 Report Share Posted October 1, 2011 This is my situation: I put acquired data on a waveform chart with update mode set to "strip chart" and I want to view old data using the chart scrollbar. The problem is that after I scroll the chart always moves automatically to the last acquired data. How can I solve this? Thanks! Quote Link to comment
jcarmody Posted October 2, 2011 Report Share Posted October 2, 2011 I won't be surprised when someone posts an easier way to do this, but I've done it by building an array and only updating the chart when the mouse isn't down. A side-effect of the way I used the Mouse Up event is that if you release the mouse with the pointer off the chart it won't be detected and the chart won't move. If that's what you want, good. If it isn't, change the Mouse Up event source from the chart to the Pane. It sounds from your post that this is the behavior you want. Quote Link to comment
jcarmody Posted October 3, 2011 Report Share Posted October 3, 2011 Could someone comment on what I've done? I half expect a link to this from the Rube Goldberg thread on the NI forum. Quote Link to comment
