Indicate goodness of fit of regression line

The goodness of fit of a regression line is the percentage
of the variance of the y values that is explained by the
dependence on the x values.

Set the alpha value of the regression line to this goodness
of fit.

Further, set the width of the regression line to a standard
deviation of the values from the regression line valies.
