: How to bend multiple lines of a graph in AI CS5? I have created a radar chart with three axes, and I would like to make all the lines in the graph curved instead of straight. I havent

Here is another solution entirely. Based on your comments which you should edit into the question.

function main(){

function bloatPoint(path, amount) {
var pts = path.pathPoints;
for(var i = 0; i < pts.length; i++){
var pos_prev = pts[(pts.length+i-1)%pts.length].anchor;
var pos = pts[i].anchor;
var pos_next = pts[(i+1)%pts.length].anchor;

pts[i].pointType = PointType.SMOOTH;
pts[i].rightDirection = add(pos,smul(0.33,sub(pos_next, pos_prev)));
pts[i].leftDirection = add(pos,smul(0.33,sub(pos_prev,pos_next)));

}

function sub(a, b){
arr=Array(2);
arr[0]=a[0]-b[0];
arr[1]=a[1]-b[1];

function add(a, b){
arr=Array(2);
arr[0]=a[0]+b[0];
arr[1]=a[1]+b[1];

function smul(a, b){
arr=Array(2);
arr[0]=a*b[0];
arr[1]=a*b[1];

function handlePaths(sel) {

Select any number of closed paths, and execute script. Results in:

How to fit a triangle to 3 points is described in this post

So it turns out that you can use a few properties of circles, lines and >triangles. You can always form a circle that hits 2 points by drawing the >center of the circle on the midpoint normal of the connecting line. You can >find the midpoint by drawing any circles that cross each other. They will >cross ate the center so if you connect the intersections you will get the >center normal. Now because 3 points have to satisfy two of these the ONLY >circles center lies at the intersection of the 2 normals.


There is a script by Hiryoki Sato called circumcircle that does this a bit faster than manually drawing lines.
