<pre>It is not possible to show a "correct" regression equation for a _line_ chart.
The reason is, that a line chart treats the x-axis values as categories, which
means, that they are not numbers. In the calculation of a regression line, the
categories are replaced with the numbers 1,2,3,...
To get a correct equation you must use an XY-chart.
My suggestions since a long time is to disable the equations for line charts.</pre>
