LabVIEW
Graph Display Distorted
I encounter an issue when displaying graph.
Attached above is when starting running, it looks smooth all the way.
However, it will suddenly appear the straight line at red circled there.
Attached this is another example happened. at around 30s there was smooth.
Once my test keep running, at 30s there will automatically appear a line as shown in photo.
I am curious what will cause this. Is anyone else face this before ?
LabVIEW 2010 is ancient.
Is this a plain graph? Chart? XYGraph?
What is the datatype?
What is the actual data?
Can you show us your code?
Hi, sorry for the late.
It is a XY Graph. Data is Numeric.
I did some data collection.
Around 5s is still having the data.
It suddenly drop down. So I have a check on the data collect. It shows zero right at that moment.
My source code :
.I am wondering why it will been reset to zero... Still troubleshooting on this portion. 😅
The most left vi is only checking for data RPM. and log the data only.
Please attach your actual VI. A truncated block diagram image not even showing the graph terminal is useless to us.
