modify the custom date format of XY graph by programmation

[Gael_Robin]

Hi everybody

I want to modify the custom date format and the custom time format of XY graph by programmation
Is it possible ?

[shawn]

Yes. Use a Property node for the XY Graph (X Scale - Format String).
I've attached an example

Ooops. The example I added was a LabVIEW 7.1 vi. Here is the same VI saved in LabVIEW 7.0:

Thanks but can I progam the time format like this : dd/MM
hh:mm

[shawn]

Yes. The LabVIEW Help explains what each part of the format string means. The help on the "Format Date/Time String" function explains this best (Go to Help Menu, select "VI, Function, & How To", then type "Format Date/Time String" into the Index tab.
For
Days/Months
Hours:Minutes
use
%d/%m
%H:%M

I can't use this format by programming for the scale name with labview 6.1

Here is also another
example of handling X-scale format programmatically under LabVIEW 6.1.

I hope this helps.

That's correct. The format string property isn't available until LabVIEW 7.0 and later. LabVIEW 6.1 may only display certain time formats. Programmatically setting time formats is even more limited. Try using the Format property on the Scale. That is the last thing I can think of.
Hope this helps- Shawn
