serial real time

[one2345]

Hey everybody!

Please help!

My project invovles reading serial data from COM1. I was able to configure serial VISA and read it and graph it. However, even though the graph is meaningful according to real time (like the watch at my hand), the time on LabVIEW (the X axis) is speeding by so quickly that when I built a clock on the block diagram, it shows that every two seconds an hour passes by on LabVIEW.... please help!!!

I'm not quite sure I understand what you mean by speeding by so quickly. The chart would only update at the same rate as your loop. You can configure the chart's X-axis any way you need. Take a look at the examples that ship with LabVIEW. Help->Find Examples, and search for "chart". You may want to start with the one called "Real-Time Chart".
