#### Histogram Chart

The Histogram Chart is a chart displaying the observed measurement distribution in bar format, with a distribution curve superimposed. Use the histogram to visually compare the measurements to the theoretical distribution and to recognize abnormalities such as bimodal distributions and outliers.

This type of chart is used in both the Chart tab and CAD tab.

To tailor a specific chart to show various reference lines, including upper and lower specification limits or control limits, or up to six sigma limits, select the Chart Options icon then Chart Display | Histogram.
