问题描述
我当前正在为我的应用程序使用 MPAndroidChart .在一种情况下,我在一个折线图中显示了三个数据集,当我单击图形上的线时,一次只能显示一个工具提示.而是根据十字线的位置,我想显示所有三个数据集的单独工具提示.
I am currently using MPAndroidChart for my application. In one scenario, I show three datasets within one linechart and when I click on the line on the graph, I get to show only one Tooltip at a time. Instead based on the cross hair position, I would like to show individual tooltip for all three datasets.
我在这里遇到了许多其他问题,但找不到我想要的东西.这是我所需输出的示例屏幕截图.我想知道这是否有可能,任何帮助将不胜感激.
I have gone through many other questions here and I couldn't find exactly what I am looking for. This is a sample screenshot of my required output.I would like to know if this is possible and any help is much appreciated.

请尝试以下&让我知道您的反馈意见
Please try with the solution below & let me know your feedback
lineChart.setOnChartValueSelectedListener(new OnChartValueSelectedListener() {
@Override
public void onValueSelected(Entry e, Highlight h) {
Highlight highlight[] = new Highlight[lineChart.getData().getDataSets().size()];
for (int j = 0; j < lineChart.getData().getDataSets().size(); j++) {
IDataSet iDataSet = lineChart.getData().getDataSets().get(j);
for (int i = 0; i < ((LineDataSet) iDataSet).getValues().size(); i++) {
if (((LineDataSet) iDataSet).getValues().get(i).getX() == e.getX()) {
highlight[j] = new Highlight(e.getX(), e.getY(), j);
}
}
}
lineChart.highlightValues(highlight);
}
@Override
public void onNothingSelected() {
}
});
