number type data to 1D array for waveform graph

[looser]

Hi all,
There is something confusing me. In my VI, I have number type of data (DBL 64) which is field value, and I am able to create waveform chart by feeding it with number type data. But then I have problem with time axis that I want to have like oscciloscope. In order to do so, I use waveform graph , but now i have to convert my number data to array. First question, is there any simple VI to easily convert number to 1d array ( that i couldnt find in the conversion VIs),.Alternatively , i have tried to use initialize array VI for conversion, which resulted in out put of "0" all the time..
Could you please tell  me  that what i m missing or dont understand properly?
thanks

Hello looser,

me again 🙂

For creating an array from numbers you should use 'Build array' from the array palette.

When replacing a waveform chart by a graph you have to collect your data in an array! A chart is collecting the data in it's history, a graph is only displaying the values you feed it.
So when doing your daq you have to build up an array with all values you want to have in the graph!

See the examples provided by LabView!

Hi GerdW,
nice to catch u again:)
as for ur anwer,  that is exactly what i thought and tried to do ( also checked buil array VI). I am connecting my number data to element input of build array VI, appended array to waveform graph. But i have broken run display saying that ""build array; contains unwired or bad terminal""?

Hi looser,

your vi seems to be ok - at least from the picture...

But (as told before): for a graph you have to collect the data. Please look at our examples using shift registers to do so!

upsss...
that was what i have been missing! holy register shift:)
thanks
