X Axis setting

[IDMHALLAM]

I am displaying the trace for an accelerometer. The plot is time/accelerometer output. The plot appears to be ok, but the actual graph disappears about 2/3 of the way along the x axis. There is a vertical line every minute that continues to the 0 point of the graph, but the data just disappears. I've run the "Test" graph, and that displays correctly. What am I doing wrong?

Chances are you don't have the History value for the channel set high enough. It defaults to 3600, which means after 3600 data points are accumulated, it will start to throw away the oldest data. Increasing this number should solve your problem. Most modern computers can easily handle histories into the 100,000's, since a data point only takes up 16 bytes of memory.

Thanks for that, problem solved.

COOL! .....Glad I found this post, as it solved a problem we had in some graphs with 8-hour spans. My staff told me we losing the traces after 1-hour

.....keep up the good work
