Guided Tour: Histograms

Another quite simple method for having a look at univariate data is to display a histogram of the data distribution. In order to display a histogram, you have to click the setup button of the plot window and select "histogram" as the type of plot. The number of bins shown in the setup window is automatically adjusted to provide an optimum histogram.

The histogram display gives you a quick overview whether some data are unimodal or multimodal. As an example just display the histogram of the variable 'petal_leng' of the data set IRIS.IDT.
