Histogram

Building a Model with Elementary Components

Histogram

The histogram shows a distribution histogram of the selected attribute. The Histogram control panel shows the minimum, maximum, number, mean, and standard deviation of the attribute that it is monitoring. This attribute can be named in a bucket that is dropped on the histogram or can be one of the states of a component that is dropped on the histogram. If a bucket is dropped on the histogram, then the bin controls for the histogram are those of the bucket. If a component is dropped on the histogram, then the bin controls are associated with the histogram and are accessible from the histogram control panel.

The histogram control panel has buttons to enable or disable automatic scaling; refresh the plot; raise the local bin controls; and to specify auxiliary controls. The latter two buttons apply if you drop a component on a histogram.

You can also drop histograms onto other histograms. This enables you to collect statistics on the minimum, maximum, mean, and standard deviation of the attribute. It is a type of batch means.
