The histogram can be used for putting the data points of a vector in different bins. Each bin holds values that are within a certain range. The number of values that falls within the range is given as the count and can be seen on the Y-axis. The histogram is useful for analyzing the distribution of the plotted vector. For example, the data in the figure below looks fairly normally distributed.

Histogram settings:

Data range: The Data range specifies which vector of the chosen matrix should be plotted.

Color: Changes the coloring of the histogram bars. The only available option is [FIXED]; all bars have the same color.

Comment: Available options are [NONE], [CUSTOM] and [CATEGORY]. With [CUSTOM] the user can enter a custom comment using the advanced settings. The custom comment will be shown in the tooltip box that appears when the mouse pointer hovers above a data point. The comment is also shown in any text box created from the table toolbar. When [CATEGORY] is selected the comment will contain either an observation category or a variable category depending on the type of plotted vector.

Bin Settings: Specifies the number of histogram bins, which is equal to the number of intervals the points of the plotted vector is divided into.
