HOW CAN I DRAW A PARABOLIC WAVEFORM???

[altenbach]

For the formula, you could use plain g, an expression node, or even the polynomial evaluation tool.

I am really sorry to disturb you, but I do not know to employ that because I am just a beginner. So may I ask you to do it for me where I really need it. I will be grateful it will be abe to do that

Contrary to what you might think, this forums is for help with programming. It is not a homework service that provides professional turnkey solutions for free.

If you have problems with this very simple task, you should start with a few tutorials. Try to solve it! If you get stuck, show us your attempt and we will tell you what you are doing wrong.

Your problem is also very ambiguous, because there is an infinite number of different parabolas that fit the description. You need at least three points to define a unique parabola.

I see that the code executes without any errors. Could you explain why do you think it is not working correctly?

Thanks a lot. Actually, I just want someone to confirm that for me as I have not deal with digitization in Labview. Thanks again
