Plotting functions in 2D array on a Graph

[TheAlPaca]

Hey all,

As an exercise I am trying to plot 2 functions placed in a 2D array on a graph, but for some reason the graph is only showing one of them.

The functions are : y = 5x+10 and y = 6x - 10.

I really don't see what I am doing wrong here, could anyone give me some more insight?


Thanks in advance,

Michiel

Based on your code, I think what you really want to use is a Chart, not a Graph.  A chart keeps a history, so it just keeps adding on to the data.  A graph will get overwritten each time you write to the terminal.  So you were only graphing a single point for each plot.

Al,

To explain a bit more of what is going on, you have two functions

y1 = 5x+10

y2 = 6x - 10

Each loop of your application you receive two outputs;

y1(Numeric) = A

y2(Numeric) = B

You build an array such that you have [A,B].  When you plot the graph you then draw a line between points {0,A} and {1,B} because LabVIEW's default behavior is to use the indeces of the array as the x-coordinates

Oh okay I get it, how can I prevent this from happening and just show A & B on their own?

As already mentioned, a chart is a better option and you would bundle the two outputs, not build a 1D array.

Alright I figured it out this way! Thanks alot for the help!

File added to how I did it.
