graph equation formula node problems

[labview1958]

I am using LV6.0. I am having some problems regarding the formula in the formula node. I hope someone can help. The vi is attached

Hi

After each line you have to write a semicolon ( ; ) and you also have to put a * before the brackets. So your formulas should look like this:

x=a*0.02;
y=0.01*(a*a + a);

Hope this helps.

Thanks. The vi can now RUN. However I am getting TWO graphs instead of ONE. One is in red. I hope you can help. The new vi is attached.

Yes, that's right. Waveform graphs and charts always show data in this way. If you want to use your x-values as x-axis and the y-values as y-axis, you have to use the xy-graph.

Attached is a screenshot of the vi.

Hope this helps.

I have done a different way and it works. Is my way also correct or is there a catch?

Hi

As I see, you now use the function "index and bundle cluster array". This results in an array of clusters.

I usually use just the bundle function, which results in a cluster of arrays.

I can't tell you if there may be problems, because I hardly use the first function. Obviously it works, but I'd suggest you to use the bundle-function, as this way is mentioned in the context help of the xy-graph.
