How to change the time scale on Dynamometer's profile

[dathenv]

I am using LabVIEW 7.0 and running the Dynamometer Kit. I have tow questions:

1) How to change the x-increment on the time scale? Right now it is fixed at 0.25 minute per mark. Changing 'x-increment' under VI Hierarchy only changes the mark before the origin (0,0). For example, I changed the value of 'x-increment' to 0.1, I get a -0.1 on the x-axis, however, everything else remains at 0.25 increments.

2) How to save/load the results of the profile? In other words, how would I save the data into files that I can recall later.

Thanks

Hi,

To address your question, are you referring to the attached dynocode.llb files? I didn't see a waveform graph or chart in these files, but I am assuming your x-increment question is pertaining to a graph you are using. To set the marker spacing on the x-scale, right-click on the front panel where your graph is located and select Properties >> Scales. Then, there is a drop down to select the x or y-axis. Choose the appropriate one and deselect Autoscale. You can then set the offset and multiplier options. The multiplier will set the marker spacing (x-increment) on the graph. Sometimes, the waveform graph doesn't modify correctly and you might want to replace it with a new waveform graph instance. Tight-click on the graph, choose Replace and then
navigate to the Waveform Graph.vi.

To address your other question regarding saving/loading the profile information, I would suggest looking at the Read From Text File.vi and Write To Text File.vi example programs that are in the LabVIEW Example Finder under Help >> Fundamentals >> File Input and Output.

Let me know if you have any further questions or if this does not resolve your issue.

Thanks again and have a great day!
