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
