我现在使用 MPAndroidChart v3.0.2。 问题是最后的数据('05일')没有显示......
这是我调试时的值 xVals : 1일, 2일, 5일
and 是来源和结果截图。
我认为'5일'进入'红圈'......但我不知道原因..
LineChart chart = (LineChart) findViewById(R.id.chart);
if (ExRegList.length() == 0) {
chart.clear();
chart.setDescription(null);
chart.setNoDataText("데이터가 존재하지 않습니다."); // There is no data.
chart.invalidate();
} else {
ArrayList<Entry> entries = new ArrayList<Entry>();
final String[] xVals = new String[ExRegList.length()];
try {
for (int i = 0; i < ExRegList.length(); i++) {
JSONObject obj = ExRegList.getJSONObject(i);
String date = obj.getString("REG_DT").split("-")[2] + "일";
xVals[i] = date;
int score = obj.getInt("ANSWER02");
switch (score) {
case 1:
entries.add(new Entry(i,3f));//매우만족
break;
case 2:
entries.add(new Entry(i,2f));
break;
case 3:
entries.add(new Entry(i,1f));
break;
case 4:
entries.add(new Entry(i,0f));//매우불만족
break;
}
}
} catch (Exception e) {
e.printStackTrace();
}
LineDataSet lineDataSet = new LineDataSet(entries, "");
lineDataSet.setLineWidth(2);
lineDataSet.setDrawCircleHole(true);
lineDataSet.setDrawCircles(true);
lineDataSet.setDrawHorizontalHighlightIndicator(false);
lineDataSet.setDrawHighlightIndicators(false);
lineDataSet.setDrawValues(false);
LineData lineData = new LineData(lineDataSet);
chart.setData(lineData);
XAxis xAxis = chart.getXAxis();
xAxis.setValueFormatter(new IndexAxisValueFormatter(xVals));
XAxis bottomAxis = chart.getXAxis();
bottomAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
bottomAxis.setDrawLabels(true);
bottomAxis.setDrawGridLines(false);
bottomAxis.setDrawAxisLine(true);
bottomAxis.setLabelCount(entries.size());
YAxis yAxis = chart.getAxisLeft();
yAxis.setLabelCount(4, true);
yAxis.setAxisMinimum(0.0f);
yAxis.setAxisMaximum(3.0f);
yAxis.setValueFormatter(new IAxisValueFormatter() {
@Override
public String getFormattedValue(float value, AxisBase yAxis) {
String format = "";
switch ((int) value) {
case 3:
format = "매우 만족";
break;
case 2:
format = "만족";
break;
case 1:
format = "불만족";
break;
case 0:
format = "매우 불만족";
break;
default:
break;
}
return format;
}
});
yAxis.setTextColor(Color.BLACK);
YAxis yRAxis = chart.getAxisRight();
yRAxis.setDrawLabels(false);
yRAxis.setDrawAxisLine(false);
yRAxis.setDrawGridLines(false);
chart.setFocusable(false);
chart.setPinchZoom(false);
chart.setDoubleTapToZoomEnabled(false);
chart.setDrawGridBackground(false);
chart.setDescription(null);
chart.getLegend().setEnabled(false);
chart.animateY(2000, Easing.EasingOption.EaseInCubic);
chart.invalidate();
最佳答案
取而代之的是:
bottomAxis.setLabelCount(entries.size());
使用这个重载版本:
bottomAxis.setLabelCount(entries.size(), true);
第二个参数,boolean force
强制具有确切的标签数。没有它,有时该方法不起作用,就像您的情况一样。从源码可以看出:
sets the number of label entries for the y-axis max = 25, min = 2, default: 6, be aware that this number is not fixed (if force == false) and can only be approximated.
关于android - (MPAndroidChart-LineChart) 我没有在我的应用程序中得到最后一个标签,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/48115765/
