Constructor Detail

ChartLinkGenerator

public ChartLinkGenerator(String urlTemplate)

Constructs a chart link generator. There are three placeholders that can be used within the url template that will be replaced with the value at a given data point on the chart. The placeholders are "{series}", "{domain}", and "{range}".
