plot

public static PlotCanvas plot(double[] data)

Create a plot canvas with the bar plot of given data.

Parameters:

data - a vector of which values will determine the heights of bars.

plot

public static PlotCanvas plot(java.lang.String id,
                              double[] data)

Create a plot canvas with the bar plot of given data.

Parameters:

id - the id of the plot.

data - a vector of which values will determine the heights of bars.

plot

public static PlotCanvas plot(double[] data,
                              java.lang.String[] labels)

Create a plot canvas with the bar plot of given data.

Parameters:

data - a vector of which values will determine the heights of bars.

labels - the labels for each bar.

plot

public static PlotCanvas plot(java.lang.String id,
                              double[] data,
