XY plot on table grid, highlight cells?

[deviousKA]

Hello,  I am new to LabView programming,  I have searched for any information but have come up short so far.

I am working on a VI in which I am connected to the serial interface of a microcontroller,  one that is controlling automotive fuel injection.  I am using visa controls and the application is finished to a point that I have the data in arrays and in certain streams that I need.

I am wondering if there is a way to input an array to a table or a graph for the X, Y axis and the Z axis.  After that,  having a real time value for both the X,Y , as an input to trace or plot its location on the table/graph (in reference to the XY axis)? 

Somehow possible to create a table of cells of which could be highlighted as a plot indicator?  Or possibly a 3d control?  I have looked through a few with some ideas,  all seem to be analyzing the data differently that I need to.

I would appreciate any tips.

Thanks!

Hi,

Have you looked at Intensity charts in LabVIEW? If I am understanding you correctly, it looks exactly like what you need.

As for highlighting cells in a table as a plot indicator, you can use the active cell and cell background color properties to change the color of a cell. I have made a crude example for the same.

Hope this helps,

Thanks Antika!,  thats pretty much what I was after in a highlighted cell table. 

I got a bit more curious and looked in the property nodes for any way that I could also input a value to the active cell (with or without highlight, color fill),  but I could not seem to find what I was after.  Is their a simple way to do this with a property node or am I off base?.

I had set up an XY graph with cursor controls earlier,  Im going to check out the intensity charts, thanks for the tip!

Hi Devious,

If you decide to go the 3-d route, this link

Hi,

Check out the Set Cell Value method. The X and Y index values that you use with this method can be converted to a cluster for choosing the active cell.

Hope this helps,
