Computation

Show Mean	Select this check box to display a line for the mean of all values in the chart.
Show Stdev	Select this check box to display two lines for the mean value plus and minus the standard deviation.
Show RSD%	Select this check box to display two lines for the mean value plus and minus the relative standard deviation.
Color and Line Style	Adjust the color and style of the respective line. See Color and Line Style.

N-Sigma

Show N-Sigma	Select this check box to display two lines for the mean value plus and minus n times sigma.
Factor	Multiplier for the sigma value.
Color and Line Style	Adjust the color and style of the lines. See Line Style.

Extrapolation to Zero

This function only applies to line charts and scatter charts (chart type Scatter - Simple): If you select this check box, RTE will add a virtual data point at the origin of the coordinate system and force the lines through this virtual data point.

Trendline

This function only applies to scatter charts (chart type Scatter - Simple): If you select this check box, RTE will draw a trendline for each series. The correlation coefficient r and determination coefficient R² values will be shown in the legend.

The following trendline calculations are available:

• Linear

• Polinomial

  NOTE: For polinomial trendlines that are extrapolated to zero, the coefficient c is set to zero in the equation y = (a * x²) + (b * x) + c.

To view a linearity curve, at least two points are required in series.
