Hello, I'm programming a software with LV2016 that uses a XY graph. The user will be able to edit the Plot legend name on the front panel. Then I use the plot names to update page caption in a tab control. After some tests, I noticed that when the user deletes the plot name via the plot legend, the page caption in the tab control keeps the previous plot name. I try to figure out where the problem comes from and it looks like the graph doesn't reset the plot name when deleting the plot legend name. The only ways I've found to reset/delete the plot name are with the properties of the graph (right click on the XY graph) or by putting an empty string in the property node of the graph, but that's not what i'm looking for. Of course I could use string controls and put them over each plot legend name but I would like to know if there is a way or a property to correctly delete the plot name by deleting the plot legend name via the front panel. I put a small exemple that describe my problem. Thanks in advance !

Indeed I ran my code with highlight execution aswell and I saw that the comparaison doesn't trigger the event. Furthermore, I noticed that when you delete the plot legend name via the front panel and you try to read the plot name with a property node, the graph keeps in memory its previous plot name, instead of returning an empty string. I think I'm going to use string controls I'll put on the different plot legend name as follows in this example. It makes the event easier to handle and allows me to write empty string in my plot legend and my tab control.
