Can you save scale settings in the Historical Trend Viewer?

[bnadeau]

I have a customer who always uses the same scale settings (max and min)when viewing data with the Historical Trend Viewer in the LabVIEW DSC module. Is there a way to save these settings as the default when the HTV is lauched? Currently, they keep reverting to the tag scaling limits. The "save settings on exit" feature does not appear to work for the scale values.

I am calling the HTV progamatically with the "Call HTV" vi and the program was originally developed using BridgeVIEW 2.1 (I have converted it to LabVIEW 7.1 and the DSC module).

Thanks.

I am not sure off hand.

A lot of the LV utilities are written in LV. The HTV may be one of these.

If so, it should be possible to get at the FP objects and manipulate their properties.

In the attached link I posted an example where I "hacked" into the tag editor to define the collumn widths. I would suspect a similar approach could be applied to set the range in the HTV.

Let me know if this approach get you anywhere.
