我创建了一个图表,显示测试期间回答的问题 (X) / 时间 (Y)。您可以在此处查看第一个问题以了解详细信息。
但现在我需要正确显示图表项目符号值,目前显示毫秒值,但我需要显示自定义 hh:mm:ss 值,就像我对 Y 轴标签所做的那样,并以某种方式自定义 Y 轴区域以正确显示完整值。下面是图表现在的样子的屏幕截图。

在丹的帮助下,我几乎得到了我想要的。这只是一个小问题。在下面的屏幕截图中查看图表值现在出现的位置。我从 AChartEngine 存储库更新到 1.1.0。addNotations 在 TimeSeries 对象上。我将代码复制粘贴到下面,将数据添加到我的 TimeSeries 实例。
myQuestionsTimeSeries.add(i, DateTimeHelper.getMillisFromTime(answer.getEstimatedAnswerTime()));
xyMultipleSeriesRenderer.addYTextLabel(DateTimeHelper.getMillisFromTime(answer.getEstimatedAnswerTime()),
String.valueOf(answer.getEstimatedAnswerTime()));
myQuestionsTimeSeries.addAnnotation(String.valueOf(answer.getEstimatedAnswerTime()), i,
DateTimeHelper.getMillisFromTime(answer.getEstimatedAnswerTime()));
此图表的代码结果:

这基本上是整个班级:
private void initQuestionsTimeChart() {
xyMultipleSeriesDataset = new XYMultipleSeriesDataset();
xyMultipleSeriesRenderer = new XYMultipleSeriesRenderer();
questionsTimeChart = ChartFactory.getLineChartView(getActivity(), xyMultipleSeriesDataset, xyMultipleSeriesRenderer);
rootView.addView(questionsTimeChart);
initSeriesData();
}
private void initSeriesData() {
createMyQuestionsSeries();
addSeriesAndRenderer(myQuestionsTimeSeries, myQuestionsRenderer);
xyMultipleSeriesRenderer.setYTitle("Questions Time");
xyMultipleSeriesRenderer.setXTitle("Questions Number");
xyMultipleSeriesRenderer.setMarginsColor(Color.argb(0, 255, 255, 255));
xyMultipleSeriesRenderer.setAxesColor(Color.BLACK);
xyMultipleSeriesRenderer.setLabelsColor(Color.BLACK);
xyMultipleSeriesRenderer.setXLabelsColor(Color.BLACK);
xyMultipleSeriesRenderer.setYLabelsColor(0, Color.BLACK);
xyMultipleSeriesRenderer.setAxisTitleTextSize(16);
xyMultipleSeriesRenderer.setLabelsTextSize(15);
xyMultipleSeriesRenderer.setYLabelsAlign(Paint.Align.RIGHT);
xyMultipleSeriesRenderer.setSelectableBuffer(20);
xyMultipleSeriesRenderer.setYLabels(0);
xyMultipleSeriesRenderer.setMargins(new int[]{ 80, 80, 80, 80 });
}
private void addSeriesAndRenderer(XYSeries series, XYSeriesRenderer renderer) {
xyMultipleSeriesDataset.addSeries(series);
xyMultipleSeriesRenderer.addSeriesRenderer(renderer);
}
private void createMyQuestionsSeries() {
myQuestionsTimeSeries = new TimeSeries("My Questions/Time");
myQuestionsRenderer = new XYSeriesRenderer();
myQuestionsRenderer.setColor(Color.BLUE);
myQuestionsRenderer.setLineWidth(3f);
myQuestionsRenderer.setPointStyle(PointStyle.CIRCLE);
myQuestionsRenderer.setFillPoints(true);
myQuestionsRenderer.setChartValuesSpacing(10f);
}
private void fillData() {
int i = 0;
for (Answer answer : getAnswers()) {
i++;
if (answer.getEstimatedAnswerTime() != null) {
myQuestionsTimeSeries.add(i, DateTimeHelper.getMillisFromTime(answer.getEstimatedAnswerTime()));
xyMultipleSeriesRenderer.addYTextLabel(DateTimeHelper.getMillisFromTime(answer.getEstimatedAnswerTime()),
String.valueOf(answer.getEstimatedAnswerTime()));
myQuestionsTimeSeries.addAnnotation(String.valueOf(answer.getEstimatedAnswerTime()), i,
DateTimeHelper.getMillisFromTime(answer.getEstimatedAnswerTime()));
}
}
}
先感谢您!
