------- Additional comments from [EMAIL PROTECTED] Sun Mar 11 01:19:39 +0000 2007 ------- Non-linear regression curves in charts are not rendered correctly in the presence of either 0 and/or negative values in the X and/or Y value. In all cases, when a certain condition is met, the lines are rendered as flat lines at the bottom of the chart. For logarithmic regression, the condition is the presence of 0 or less (negative number) in the X set of data. For exponential regression, the condition is the presence of a negative number in the Y set of data. For power (polynomial?) regression, the condition is the presence of 0 or less (negative number) in the X set of data OR the presence of a negative number in the Y set of data. I assume it is the related to the mathematical nature of logarithms, exponents, and polynomials of the 2nd degree, but Excel seems to render the equivalent trend line correctly. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
