Switching between 2 sets of values controlling the y axis on an xy graph.

[Detox92]

Morning all,

I am very new to this (like 2 days now) and will soon be sitting the Labview core 1 and measurement fundamentals, so bare with me!!

Basically I am extracting 2 values from a string that is outputted from a board I have through IP, one value is for mains voltage and the second measurement is for battery voltage.

I would like the option to use a control switch to differentiate between what is being inputted the the graph at the push of a button.

Is there a way of doing this?

Thanks a lot

Yeah its possible (though I dint understand your problem statement completely, I'm confident it is possible)...!!

--> you can even plot both (MAINS and BATTERY voltage) in the same graph...

well do you want to use a control (say a toggle switch) to control what voltage to display (either MAINS or BATTERY)... is it??

can u attach few of the samples reading here or what ever u coded so far...??

Hi thanks for the quick response,

as i said this is my first go with labview and less than a week trying so please bare with me on the vi as i am probably doing things the long winded way.

but basically i am reading from a string and taking the voltage when a system is running on mains power and also from a different section when the system is running on battery power. I would like the graph to have 2 possible inputs which as you said can be toggled either or.

i have attached my vi

Thanks alot!!

Did you try Select function ?

Spot on thanks!

Simple as that!
