我注意到有一个问题BarChart of MPAndroidChart并需要修复。首先是我的代码：
this.barChart = (BarChart) view.findViewById(R.id.bar_fragment_bar_chart);
this.barChart.setDrawYValues(true);
this.barChart.setDrawXLabels(false);
this.barChart.setDrawValueAboveBar(true);
this.barChart.setDrawBorder(false);
this.barChart.setDrawGridBackground(false);
this.barChart.setDrawHorizontalGrid(true);
this.barChart.setDrawVerticalGrid(false);
this.barChart.setDrawBarShadow(false);
this.barChart.setDescription("");
this.barChart.setNoDataTextDescription("");
this.barChart.set3DEnabled(false);
My xValues是简单的日期：
ArrayList<String> xValues = new ArrayList<String>();
for(int i = 0; i < measureDataListEntry.size(); i++) {
String StringValue = measureDataListEntry.get(i).getTime();
Long value = Long.parseLong(StringValue) * 1000;
DateFormat dateFormat = new SimpleDateFormat("dd.MM.yyyy", Locale.GERMAN);
String date = dateFormat.format(new Date(value));
xValues.add(date);
}
现在我有多个数据集：
ArrayList<BarEntry> yValuesMonday = new ArrayList<BarEntry>();
ArrayList<BarEntry> yValuesTuesday = new ArrayList<BarEntry>();
ArrayList<BarEntry> yValuesWednesday = new ArrayList<BarEntry>();
ArrayList<BarEntry> yValuesThursday = new ArrayList<BarEntry>();
ArrayList<BarEntry> yValuesFriday = new ArrayList<BarEntry>();
ArrayList<BarEntry> yValuesSaturday = new ArrayList<BarEntry>();
ArrayList<BarEntry> yValuesSunday = new ArrayList<BarEntry>();
for(int i = 0; i < measureDataListEntry.size(); i++) {
String stringValue = measureDataListEntry.get(i).getValue();
int dayOfWeek = Helper.getDayOfWeek(measureDataListEntry.get(i).getTime());
float value = Float.parseFloat(stringValue);
switch(dayOfWeek) {
case Calendar.MONDAY:
yValuesMonday.add(new BarEntry(value, i));
break;
case Calendar.TUESDAY:
yValuesTuesday.add(new BarEntry(value, i));
break;
case Calendar.WEDNESDAY:
yValuesWednesday.add(new BarEntry(value, i));
break;
case Calendar.THURSDAY:
yValuesThursday.add(new BarEntry(value, i));
break;
case Calendar.FRIDAY:
yValuesFriday.add(new BarEntry(value, i));
break;
case Calendar.SATURDAY:
yValuesSaturday.add(new BarEntry(value, i));
break;
case Calendar.SUNDAY:
yValuesSunday.add(new BarEntry(value, i));
break;
}
}
BarDataSet barDataSetMonday = new BarDataSet(yValuesMonday, this.getResources().getString(R.string.text_monday));
barDataSetMonday.setColor(this.getResources().getColor(R.color.diagramGreenColor));
BarDataSet barDataSetTuesday = new BarDataSet(yValuesTuesday, this.getResources().getString(R.string.text_tuesday));
barDataSetTuesday.setColor(this.getResources().getColor(R.color.diagramOrangeColor));
BarDataSet barDataSetWednesday = new BarDataSet(yValuesWednesday, this.getResources().getString(R.string.text_wednesday));
barDataSetWednesday.setColor(this.getResources().getColor(R.color.diagramPinkColor));
BarDataSet barDataSetThursday = new BarDataSet(yValuesThursday, this.getResources().getString(R.string.text_thursday));
barDataSetThursday.setColor(this.getResources().getColor(R.color.diagramBlackColor));
BarDataSet barDataSetFriday = new BarDataSet(yValuesFriday, this.getResources().getString(R.string.text_friday));
barDataSetFriday.setColor(this.getResources().getColor(R.color.diagramBlueColor));
BarDataSet barDataSetSaturday = new BarDataSet(yValuesSaturday, this.getResources().getString(R.string.text_saturday));
barDataSetSaturday.setColor(this.getResources().getColor(R.color.diagramRedColor));
BarDataSet barDataSetSunday = new BarDataSet(yValuesSunday, this.getResources().getString(R.string.text_sunday));
barDataSetSunday.setColor(this.getResources().getColor(R.color.diagramYellowColor));
ArrayList<BarDataSet> dataSets = new ArrayList<BarDataSet>();
dataSets.add(barDataSetMonday);
dataSets.add(barDataSetTuesday);
dataSets.add(barDataSetWednesday);
dataSets.add(barDataSetThursday);
dataSets.add(barDataSetFriday);
dataSets.add(barDataSetSaturday);
dataSets.add(barDataSetSunday);
BarData data = new BarData(xValues, dataSets);
this.barChart.setData(data);
this.barChart.animateY(1000);
我现在的问题是xLabels和xValues根本不匹配：
酒吧被放置在远远落后于xLabels并且最后一个条目和最后一个条目之前的条目之间有非常大的空间。
我还测试了将所有数据放入一个数据集中时的外观。这xLabels也不匹配xValues:
我该如何解决这个问题？
EDIT
您在此处看到的日期xLabels属于酒吧。那么为什么这个位置是xLabel离酒吧那么远？
EDIT 2:
With LineChart:
protected void initData() {
List<MeasureDataListEntry> measureDataListEntry = null;
if(this.favourite) {
measureDataListEntry = this.sessionMeasureDataListFavourite.getMeasureDataList().getMeasureDataListEntries();
} else {
measureDataListEntry = this.sessionMeasureDataList.getMeasureDataList().getMeasureDataListEntries();
}

ArrayList<Entry> yValuesTuesday = new ArrayList<Entry>();
ArrayList<Entry> yValuesWednesday = new ArrayList<Entry>();
ArrayList<Entry> yValuesThursday = new ArrayList<Entry>();
ArrayList<Entry> yValuesFriday = new ArrayList<Entry>();
ArrayList<Entry> yValuesSaturday = new ArrayList<Entry>();
ArrayList<Entry> yValuesSunday = new ArrayList<Entry>();
for(int i = 0; i < measureDataListEntry.size(); i++) {
String StringValue = measureDataListEntry.get(i).getTime();
Long value = Long.parseLong(StringValue) * 1000;
DateFormat dateFormat = new SimpleDateFormat("dd.MM.yyyy", Locale.GERMAN);
String date = dateFormat.format(new Date(value));
xValues.add(date);
}
for(int i = 0; i < measureDataListEntry.size(); i++) {
String stringValue = measureDataListEntry.get(i).getValue();
int dayOfWeek = Helper.getDayOfWeek(measureDataListEntry.get(i).getTime());
float value = Float.parseFloat(stringValue);
switch(dayOfWeek) {
case Calendar.MONDAY:
yValuesMonday.add(new Entry(value, i));
break;
case Calendar.TUESDAY:
yValuesTuesday.add(new Entry(value, i));
break;
case Calendar.WEDNESDAY:
yValuesWednesday.add(new Entry(value, i));
break;

break;

break;

break;

一切工作正常：
