Hi SebN74,

here is a picture of an XY graph with computer's time in X axis.
You need to modify X axis parameters to show the time in X axis.

Hope it helps!

Hi,

I build the VI you did to see how it works : that's excatly what I want,

But when I apply your technique to my VI, it doesn't work. There's only 1:00:00 in X-axis, and no curve is drawn.

I receive data from serial port, I've deleted your random number and plugged my data (DBL) in its place. (See picture.

Thanks for all,

Seb.

Hi Seb,

In fact, you forgot the use of the "shift register" which will memorize the values for the graph.
In your example, the X and Y arrays are reinitialized at each loop iteration. To avoid this, put a "shift register" on the loop.

Here is my previous pic with the "shift register" marked.
To put a "shift register" on a loop, right-click on this loop and select the "Add shift register" option.
