我发现BarChart
的{{1}}存在问题,需要修复。首先是我的代码:
MPAndroidChart
我的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);
是简单日期:
xValues
现在我有多个数据集:
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);
}
我现在的问题是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);
和xLabels
根本不匹配:
这些小条位于xValues
的后面,最后一个条目与最后一个条目之前的条目之间有很大的空间。
我还测试了将所有数据放入一个数据集时的外观。 xLabels
也与xLabels
:
我该如何解决这个问题?
修改
您在xValues
中看到的日期属于该栏。那么为什么xLabels
的位置离条不远呢?
编辑2:
使用xLabel
:
LineChart
一切正常:
答案 0 :(得分:1)
我不确定你想要什么。 但将x标签置于栏杆上方,请致电:
chart.getXLabels().setCenterXLabelText(true);
对于条形图内的组,也许您应该查看示例项目,看看这里做了什么:
<强>更新强>:
如果您只是希望每天都有单独的颜色,请将所有条目放在一个DataSet中,并将7种颜色(每天一个)添加到数据集中。 在这种情况下,x值数组需要与您提供的条目数组一样长,包含不同的日期。
