One-dimensional Plots

Attributes in a dataset are stored as one-dimensional arrays, thus they can be plotted for example as a histogram or as a scatter plot. The Dataset offers the following methods:

plot_histogram(name, ...)

creates a histogram of attribute name using matplotlib.

r_histogram(name, ...)

creates such histogram including a density line using the rpy library.

plot_scatter(name_x, name_y, ...)

creates a scatter plot for two attributes using matplotlib.

r_scatter(name_x, name_y, ...)

creates a scatter plot using the rpy library.
