  1. I'm writing some LabVIEW software to store and display data from a variety of data sources, mostly through an NI DAQ board. I'm displaying the data (stored in an SQLite database) on an XYGraph. I would like to have a toggle-able, probably semi-transparent box listing each of the plots on the graph, with the option to turn the plots on/off by clicking, along with some grouping of similar plots (all temperature measurements, or all measurements from experiment #5, etc). The Bloomy post at http://www.ni.com/newsletter/51918/en/ gives me semi-transparent panels pretty easily (in fact, this can conceivably be tri-state, since I have on, off and invisible :D) I've already programmed a simple multi-column listbox for something else in this project that switches symbols and handles double-click, mouse up/down, etc, so I could maybe use a modified version of that to hold my plots. I have never successfully used an XControl for anything, but when I come to problems involving collections of strange custom controls, I always think, is this what an XControl is for? So, do I need an XControl here? Or will I just be diving into another rabbit-hole leading to yet another unsuccessful XControl attempt? If so, what should I be using instead? In case it matters, the bulk of the project uses NI's Actor Framework to handle separate sections, and the graph is inside a subpanel, inside another subpanel. Some images of current pieces. The parent holds the scrollbar, and my current no-op (except show/hide on the little menu button bottom left) overlay (not at all transparent). The child holds the actual graph, and an ugly global variable mean (I needed it quickly for a colleague's use...). The child is embedded in a subpanel of the parent (above the scrollbar) and the parent is embedded in a subpanel of the MainUI's 'Actor Core.vi'.
  2. Hello, In matlab the plot data can be save as a *.png,*.jpeg, and so on and even a pretty good option *.fig. Later when the *.fig is opened you have the real plot as before and this can be edited like changing the legeng , x and y labels, color of the plot etc,. Is there any option like this in labVIEW. I have seen options like saving the data into excel and to different image formats. Is there any special tool kit or add in functions??
  3. Hello to everybody, I'm wondering to find a solution to this problem... I have an xy-graph and I would like to insert programmatically some text label connected to certain x-y coordinates of the plot itself. Does somebody know if it is possible? ... and have an idea on how to implement such behaviour? Thanks Max
