How to Overlay a Preset Graph On to a graph during acquisiton from source?

[Kam1762]

Hi guys,

So we have a program that measures the force Vs displacement of the item being pressed on the machine and outputs a graph on the front panel Live. What i am trying to do is have a preset boundary graph available on the screen so when the item is being pressed the user can see if the ranges are within the limits.

How can i go about this?

Thanx

HI,

what datatypes do you want to use for your graph and can you draw a quick example of how it should look like in the end?

As your data is being collected live, write the set of collected data points to an XY or Waveform graph, along with also writing the complete overlay plots as well. They'll all be drawn together on the same grid. Give the overlay plots different styles (color, line types, etc.) to distinguish them from the collected data plot.

Hi,

Just getting in x and y..i have attached an example of what the graph should look like.

So when the process starts I want the red lines (boundary) to be already on the screen and then the blue line begins to form as data is collected. The aim is so that the user can see if the blue line is within the boundary or not before the graph ends.

 I am already getting the blue line. I just need to know how to add the pre-set red line with the co ordinates into the graph.

Thank You

So all I really need to do is add the red line into the graph. Hope this is clearer.

I made a quick example of what I think you want. Maybe you can start with that.
