pause or freeze a waveform chart

[flafi]

Hi,

I'm using a waveform chart to display data over a long period, for example, 10 hours, and I don't want to lose this data. But I want to be able to freeze the chart so that I can look closely at one section, while the data is still being collected, without pausing or stopping the program from reading the data and saving it in the chart's buffer. I know that I can do this using the waveform graph, but I don't want to use that, because the waveform chart is more suitable. I read some answers about using two charts, and making one of them invisible to read the data while I freeze the other one, but that would result in too much data being stored, because of the second chart's buffer. Does anyone know how I can freeze/pause the waveform chart?

I'm pretty sure the chart is limited in its scope as a datalogger.  It wasn't designed for the behavior you desire so you'll need to code your own display with a graph and data arrays.  The good news is it gives you the chance to add some nice functionality that would be impossible with a chart even if it could be paused.

If you think this chart feature has merit you can suggest it in the idea exchange:  http://forums.ni.com/t5/ideas/v2/ideaexchangepage/blog-id/labviewideas
