Hi,
I'm struggling to work out how to display an array of timestamps on the intensity colour graph.
Firstly, because it is not an XY graph, I can't bundle the timestamp and data arrays before displaying them. Secondly, I cannot use a 2D array as a waveform, as I would with a waveform graph. Am I correct in saying that you cannot pass a timestamp into the intensity graph like you would on an XY graph or a waveform graph?
I have a 2D array of temperature data recorded over a one month period, at 30 minute intervals. Each log has 1500 temperature readings. This results in an array that is approximately 1200 X 1500. The sampling was not continuous, due to some computer down time. I do have the time stamp for each log though, which exists as a separate 1D array in Labview.
Could someone help me know if I am able to use the graph property nodes to manually enter X-scale range parameters as well as marker readings?
Regards,
Eddie

Hi Eddie,
no, you're not able to show timestamps...
The intensity graph shows 2d arrays of data, it's scales only show the indices.
But you can use a cursor: read the cursor position and display the corresponding timestamp in a seperate indidcator.
