ChartWidgetThis can be called at any time on the widget and facilitates changing the titles on a chart in response to a filter or click event which may cause the SQL and data to change. This method may be called on a PieChartWidget as well, but only the main title will be changed.

This can be used to dynamically change the axis title, such as in response to a refresh event. Even if the chart was originally created without this axis title, calling this method will add the title to the chart.
Note that for an XYChartWidget, setting the domain title via setDomainAxisLabels() will override this method.

This is primary aimed at debugging by providing a view into what a bar or line chart's dataset looks like. A sample use case would be:
When the code is executed, the dashboard utility will display a message box with a tabular view of the chart's datasetmyLineChartWidget!.viewDataSet()
public DefaultCategoryDataset getDataset()
Note that PieCharts return a DefaultPieDataset, BarCharts and LineCharts return a DefaultCategoryDataset, and XYCharts return an XYSeriesCollection
