set x-axis of waveform chart with input

[kmarcella]

Hi,

I need to set the x-axis on all my waveform charts to a certain number of minutes which is an input (Time Target) of the user. What is the best way to do this? I am fairly new to Labview and programming so please bear with me.

Hi kmarcella,

Check out this article about the different types of graphs in LabVIEW: http://zone.ni.com/reference/en-XX/help/371361J-01/lvconcepts/types_of_graphs_and_charts/

If you are talking about formatting check out this VI: http://zone.ni.com/reference/en-XX/help/371361J-01/lvconcepts/customizing_graphs_and_charts/

Regards,

Thanks for the articles.

One more question: Is the default x-axis in units of seconds? And if I wanted it to be in minutes, how would I change that? Thanks!

The x axis has no units. It simply increments by one as the default. You can choose an offset and multiplier to change this and you can optionally change the representation to absolute or relative time. Look at the formatting options.
