无论如何都要显示textarea(用于插入自定义文本)而不是工具提示点击gwt highcharts中图表系列上的数据点,或者它只能显示图表上的工具提示,而不是图表外? / p>
chart.setSeriesPlotOptions(new SeriesPlotOptions().setPointClickEventHandler(new PointClickEventHandler() {
@Override
public boolean onClick(final PointClickEvent pointClickEvent) {
Point[] points = chart.getSelectedPoints();
int posX = pointClickEvent.getScreenX();
int posY = pointClickEvent.getScreenY();
return true;
}
}));
我无法理解如何为textarea设置位置,有什么建议吗?
EDIT:
Anyone already used annotations or similar with Java in highcharts gwt?
