Displaying a formula in a chart

[Yves]

Hi
how can I display a formula (such as y(x)=a3*x^3+a2*x^2) in a diagram?
thanks for your help.

If you mean showing text in your chart/graph, you could use "simple string" indicator on top of the graph or use cursor-text.

Sorry for my unprecise question.
I meant, I have a formula and I want to display generate its waveform in a graph. How do I do this?

[PdB]

An example is "Waveform Graph.vi" in the examples area of LV. Replace the formula in the "for loop" by your formula. Or use a formula node.
