2D array to Tensity graph,How to hide the picture when no data arrive, and show with new data come?

[YoungHang]

Hello,

    I have a  U16 2D array,which will  change value every 1 send ,  I know how to draw  intensity graph, but I do not want the graph show all the time except when new data coming, I mean the graph always hides, and popup when new data is coming. How can I achieve this?And I am using Labview 2011.

   Hope for your help!

  Thank you!

Did you try the Visible property of the graph? Any time you can turn ON/OFF depending on the data.

I have tried, but the major difficity is how to achieve "popup"?

If you want a pop-up, then create a seperate VI with just the graph and update the data to it (using Global variable/Functional Global). You can keep the window as floating, so whenever the data comes you can pop-up the window inside that VI.
