PHP smoothed line graph function

[michael1212]

Hi all,

Is there an extention available for PHP to smooth out a line graph. The line should go through all the points but must be smoothed out. Should be similar to Excel's "smoothed line" option when ploting a line graph. Thanks!

I think another term for what you're looking for is "spline curve graph". I recommend you take a look at JpGraph
