How to plot data sent through serial port by controlling knobs simultaneously

[samtha]

Hi 

I want to plot data by controlling two knobs simultaneously and plot the values according to my control using serial port communication but the problem is that the plot on the graph alternates between the two controls its not changing according to my control for eg if i move the knob1 to 1000 and knob 2 to 4000 these values alternate on the graph i have placed a select control still the problem is not solved can u help me please thank you in advance

With regards

Run the VI again and when the values are plot on the graph, go to Edit -> Make Current Values Default. Then post the VI.

Hmm there is nothing on the chart. Is it possible for you to post a screenshot of the chart after you run the VI?

Your VI CANNOT plot more than once since you do not have the code in a loop. Do NOT use the run continuous button. I also fail to see how you think anything can be simultaneous since you are using the same port. The for loop you have is also very strange. That doesn not belon there at all.
