Smoothing lines in a line graph?

I have a very basic line graph question. I would like to change the way that the line is drawn between data points to make the line 'arc' and smoothly 'flow' between the points rather than a direct line between data points.

Is there any way to do this? Perhaps a setting that I'm not seeing? perhaps something in the code behind that I can specify that would allow this?

Thanks!

Check up on "line of best fit" in the doc. One regression line options that is available is a smoothing line. It's been a while, but I have used this in the past.

I think this will do it

setSmoothLines(true);

Be aware that using setSmoothLines(true); in 7.1.3 (at least - not checked 7.6.2 yet) causes the value of the points to be the same throughout the line (equal to the first value) in the tool tip pop up.

Thanks for the replies!
Tony: I tried the setsmoothlines in 7.6.2 and it just renders the line as a set of unconnected Dots, but the hover-over values are good.

Not sure how smoothlines renders as dots...but I guess this smooth line luxury may be something best left to the Excel users.
