Hi all- I want to basically plot a user defined function discretely. Let's say f[x] is the function. What I want to do is: ListPlot[f[i],{i,0,1,0.1}] So I just want to plot the function with 10 arguments from 0 to 10 with incremental of 0.1. However, when we plot it, the x-axis is just the index which is 1 to 10 rather than 0 to 1. Is there anyway to fix this? Thanks JK Hi, Try this: f[x_] := Sin[4 x]; ListPlot[Table[{i, f[i]}, {i, 0, 1, 0.1}]] You may now define an expression to plot any custom-defined function (if I got your intention correctly). Say, like this: plotFunction[f_] := ListPlot[Table[{i, f[i]}, {i, 0, 1, 0.1}]]; This will work with any custom function, f[x], but you need first to define it. Try it, for example, with Cos[3x]: f[x_] := Cos[3 x]; plotFunction[f] Have fun, Alexei Alexei BOULBITCH, Dr., habil. IEE S.A.
