styleFor

public static String styleFor(Color color,
                              int index)

Returns the style to be applied for a given Color to a XYChart.Series.

The returned style is obtained changing the CHART_COLOR_i, CHART_COLOR_i_TRANS_20 and CHART_COLOR_i_TRANS_70 standard JavaFX chart colors (where i is a number in the 1..8 range) to the given color.

Parameters:

color - The Color for which CSS style string appropriate for a chart XYChart.Series should be created.

index - The index of the XYChart.Series in the chart. The ( index % 8 ) + 1 value will be used to decide which of the 8 standard chart colors will be overridden in the returned style string.

Returns:

A style string overriding one of the default JavaFx 8 chart colors with the given one.

Throws:

NullPointerException - If color is null.

IllegalArgumentException - If (@code index} is negative.

public static String styles(int horizontal,
                            int vertical,
                            int longitudinal)

Return the styles string to be applied to a chart.

As in JavaFX 8 colors will be used. If the given indexes are non-negative, then special colors will be used to represent horizontal (red), vertical (blue) and longitudinal (green) series.

Parameters:

horizontal - The index of the horizontal series. If non-negative red will be used for the series.

vertical - The index of the vertical series. If non-negative blue will be used for the series.

longitudinal - The index of the longitudinal series. If non-negative red will be used for the series.

Returns:

The styles string to be applied to a chart.
