Statistical Plots
The Statistics Toolbox adds specialized plots to the extensive graphics capabilities of MATLAB.
- Box plots are graphs for describing data samples. They are also useful for graphic comparisons of the means of many samples (see One-Way Analysis of Variance (ANOVA)).
- Distribution plots are graphs for visualizing the distribution of one or more samples. They include normal and Weibull probability plots, quantile-quantile plots, and empirical cumulative distribution plots.
- Scatter plots are graphs for visualizing the relationship between a pair of variables or several such pairs. Grouped versions of these plots use different plotting symbols to indicate group membership. The
gname function can label points on these plots with a text label or an observation number.
The plot types are described further in the following sections:
