Method Detail

createFromList

public static BarChart createFromList(java.util.List<? extends java.lang.Number> list,
                                      java.awt.Paint barPaint)

Create a simple BarChart that is a view on the given list. This means that changes in the given list will be visible in the returned chart.

The chart will contain value strings of the values in the list, with an unspecified string format.

If any of the values in the given list is null, then 0.0 will be used as the value.

Parameters:

list - The list

barPaint - The paint (color) to use for the bars

Returns:

The BarChart

createFromList

public static BarChart createFromList(java.util.List<? extends java.lang.Number> list,
                                      java.awt.Paint barPaint,
                                      boolean paintLabels,
                                      boolean paintValueStrings)

Create a simple BarChart that is a view on the given list. This means that changes in the given list will be visible in the returned chart.

If any of the values in the given list is null, then 0.0 will be used as the value.

Parameters:

list - The list

barPaint - The paint (color) to use for the bars

paintLabels - Whether the chart should have labels. These will just be the indices of the bars.

paintValueStrings - Whether the chart should have value strings. These will be the string values of the values, in an unspecified format.

Returns:

The BarChart

computeMin

public static double computeMin(BarChart barChart)

Computes the minimum value that appears in the given BarChart. Returns POSITIVE_INFINITY if the given chart is empty.

Parameters:

barChart - The BarChart

Returns:

The minimum value

computeMax

public static double computeMax(BarChart barChart)

Computes the maximum value that appears in the given BarChart. Returns NEGATIVE_INFINITY if the given chart is empty.

Parameters:

barChart - The BarChart

Returns:

The maximum value

getMin

public static double getMin(double optionalMin,
                            BarChart barChart)

If the given optional value is not NaN, then it will be returned. Otherwise, the minimum of the given BarChart will be returned. If the BarChart does not have any bars, then 0.0 will be returned.

Parameters:

optionalMin - The optional minimum value

barChart - The BarChart

Returns:

The minimum value

getMax

public static double getMax(double optionalMax,
                            BarChart barChart)

If the given optional value is not NaN, then it will be returned. Otherwise, the maximum of the given BarChart will be returned. If the BarChart does not have any bars, then 1.0 will be returned.

Parameters:

optionalMax - The optional maximum value

barChart - The BarChart

Returns:

The maximum value
