Bars
Histogram chart bars, drawn in blue, represent the count of data points where the sample mean falls within the range covered by that bar.
Probability Curve
The probability curve is drawn in black, and is used to give a general idea of the shape of the distribution. The type of distribution may be determined by viewing the Distribution stat.
Specification Lines
Specification lines are drawn vertically in light blue, using the dashdot pattern. Specification lines are only drawn if Show Specs is checked and specifications have been set on the Characteristic.

- Modifying bar colors.
