Hi Scott,
I have just checked myself. Using your data in Excel 2007, with logarithmic regression, I get the formula:
y = 4.549 * ln(x) - 0.359
r^2 = 0.955
I tried the same data in ChartDirector by hard coding them in the source code. I have attached my testing code (which is written in ASP/VBScript), and a screen shot to show the result. It is exactly the same as Excel.
If in your case, the result is different, is it possible to attach your test code and the resulting image?
Hope this can help.
Regards
Peter Kwan
