Method Detail

isValidChart

public boolean isValidChart()

Description copied from interface: oracle.dss.graph.pfj.BadDogCallback

Does the chart pass the "bad dog" tests? This is a way to: 1) Pre-validate the chart data yourself instead of having Perspective for Java validate the data. You must return true if the data is ok or return false if data is not ok 2) If you don't want to handle any validation of data and want Perspective for Java to validate it, throw the AssertionException exception and Perspective for Java will perform the Validation of the chart data prior to drawing. Most users would choose to pick option 2.
