如何在 Horizo​​ntalBarChart 中显示右侧的标签和左侧的值?

本文介绍了如何在 Horizo​​ntalBarChart 中显示右侧的标签和左侧的值?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 使用 但这是我的要求的一个例子请欣赏一些帮助.感谢您的时间 解决方案 几天前我实施了类似的方案.这是代码...公共类 MainActivity 扩展 AppCompatActivity {受保护的 Horizo​​ntalBarChart mChart；@覆盖protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ArrayList标签 = 新的 ArrayList();label.add("一月");label.add("二月");label.add("三月");label.add("四月");label.add("五月");label.add("六月");mChart = (Horizo​​ntalBarChart) findViewById(R.id.barChart);mChart.setDrawBarShadow(false);mChart.setDrawValueAboveBar(true);mChart.getDescription().setEnabled(false);mChart.setPinchZoom(false);mChart.setDrawGridBackground(false);XAxis xl = mChart.getXAxis();xl.setPosition(XAxis.XAxisPosition.BOTTOM);xl.setDrawAxisLine(true);xl.setDrawGridLines(false);CategoryBarChartXaxisFormatter xaxisFormatter = new CategoryBarChartXaxisFormatter(labels);xl.setValueFormatter(xaxisFormatter);xl.setGranularity(1);YAxis yl = mChart.getAxisLeft();yl.setPosition(YAxis.YAxisLabelPosition.INSIDE_CHART);yl.setDrawGridLines(false);yl.setEnabled(false);yl.setAxisMinimum(0f);YAxis yr = mChart.getAxisRight();yr.setPosition(YAxis.YAxisLabelPosition.INSIDE_CHART);yr.setDrawGridLines(false);yr.setAxisMinimum(0f);ArrayListyVals1 = new ArrayList();for (int i = 0; i dataSets = new ArrayList();dataSets.add(set1);BarData 数据 = new BarData(dataSets);data.setValueTextSize(10f);data.setBarWidth(.9f);mChart.setData(数据);mChart.getLegend().setEnabled(false);}公共类 CategoryBarChartXaxisFormatter 实现 IAxisValueFormatter {ArrayList值；public CategoryBarChartXaxisFormatter(ArrayList values) {this.mValues = 值；}@覆盖公共字符串 getFormattedValue(浮点值，AxisBase 轴){int val = (int) 值；字符串标签 = "";如果 (val >= 0 && val < mValues.size()) {标签 = mValues.get(val);} 别的 {标签 = "";}退货标签；}}}结果希望这会有所帮助.Drawing a horizontal bar chart using MPAndroidChart 3.0.2. the values are shown on the right of the bars. I could use setValueFormatter and use IAxisValueFormatter interface to display the labels on the right. But the values are not displayed now. { HorizontalBarChart barChart = (HorizontalBarChart) itemView.findViewById(R.id.barChart); BarData data = new BarData(); ArrayList<BarEntry> valueSet1 = new ArrayList<>(); ArrayList<String> labels = new ArrayList<>(); labels.add("January"); labels.add("February"); labels.add("March"); labels.add("April"); labels.add("May"); labels.add("June"); ArrayList<String> ylabels = new ArrayList<>(); int dataCount=0; for (int i=0;i<6;++i) { BarEntry entry = new BarEntry(dataCount,(i+1)*2); valueSet1.add(entry); ylabels.add(" "+i); dataCount++; } List<IBarDataSet> dataSets = new ArrayList<>(); BarDataSet bds = new BarDataSet(valueSet1, " "); bds.setColors(ColorTemplate.MATERIAL_COLORS); String[] xAxisLabels = labels.toArray(new String[0]); String[] yAxisLabels = ylabels.toArray(new String[0]); bds.setStackLabels(xAxisLabels); dataSets.add(bds); data.addDataSet(bds); data.setDrawValues(true); data.setBarWidth(0.4f); XAxis xaxis = barChart.getXAxis(); xaxis.setDrawGridLines(false); xaxis.setPosition(XAxis.XAxisPosition.BOTTOM); xaxis.setGranularityEnabled(true); xaxis.setGranularity(1); xaxis.setDrawLabels(true); xaxis.setLabelCount(dataCount+1); xaxis.setXOffset(10); xaxis.setDrawAxisLine(false); CategoryBarChartXaxisFormatter xaxisFormatter = new CategoryBarChartXaxisFormatter(xAxisLabels); xaxis.setValueFormatter(xaxisFormatter); YAxis yAxisLeft = barChart.getAxisLeft(); yAxisLeft.setEnabled(false); YAxis yAxisRight = barChart.getAxisRight(); yAxisRight.setPosition(YAxis.YAxisLabelPosition.INSIDE_CHART); yAxisRight.setDrawGridLines(false); yAxisRight.setDrawAxisLine(false); Legend legend = barChart.getLegend(); legend.setEnabled(false); barChart.setFitBars(true); barChart.setData(data); barChart.setDescription(null);}public class CategoryBarChartXaxisFormatter implements IAxisValueFormatter { private String[] mValues; public CategoryBarChartXaxisFormatter(String[] values) { this.mValues = values; } @Override public String getFormattedValue(float value, AxisBase axis) { int val = (int)value; String label=""; if(val>=0 && val<mValues.length) { label= mValues[val]; } else { label= ""; } return label; }}requirement is to display label strings on the right and a number on the left corresponding to each bar.I did check some stack overflow and google it but didn't find anything that works so far.i get thisbut this is an example of my requirementDo appreciate some help.Thanks for your time 解决方案 I implemented something similar just a few days back. Here's the code...public class MainActivity extends AppCompatActivity { protected HorizontalBarChart mChart; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ArrayList<String> labels = new ArrayList<>(); labels.add("January"); labels.add("February"); labels.add("March"); labels.add("April"); labels.add("May"); labels.add("June"); mChart = (HorizontalBarChart) findViewById(R.id.barChart); mChart.setDrawBarShadow(false); mChart.setDrawValueAboveBar(true); mChart.getDescription().setEnabled(false); mChart.setPinchZoom(false); mChart.setDrawGridBackground(false); XAxis xl = mChart.getXAxis(); xl.setPosition(XAxis.XAxisPosition.BOTTOM); xl.setDrawAxisLine(true); xl.setDrawGridLines(false); CategoryBarChartXaxisFormatter xaxisFormatter = new CategoryBarChartXaxisFormatter(labels); xl.setValueFormatter(xaxisFormatter); xl.setGranularity(1); YAxis yl = mChart.getAxisLeft(); yl.setPosition(YAxis.YAxisLabelPosition.INSIDE_CHART); yl.setDrawGridLines(false); yl.setEnabled(false); yl.setAxisMinimum(0f); YAxis yr = mChart.getAxisRight(); yr.setPosition(YAxis.YAxisLabelPosition.INSIDE_CHART); yr.setDrawGridLines(false); yr.setAxisMinimum(0f); ArrayList<BarEntry> yVals1 = new ArrayList<BarEntry>(); for (int i = 0; i < 6; i++) { yVals1.add(new BarEntry(i, (i+1)*10)); } BarDataSet set1; set1 = new BarDataSet(yVals1, "DataSet 1"); ArrayList<IBarDataSet> dataSets = new ArrayList<IBarDataSet>(); dataSets.add(set1); BarData data = new BarData(dataSets); data.setValueTextSize(10f); data.setBarWidth(.9f); mChart.setData(data); mChart.getLegend().setEnabled(false); } public class CategoryBarChartXaxisFormatter implements IAxisValueFormatter { ArrayList<String> mValues; public CategoryBarChartXaxisFormatter(ArrayList<String> values) { this.mValues = values; } @Override public String getFormattedValue(float value, AxisBase axis) { int val = (int) value; String label = ""; if (val >= 0 && val < mValues.size()) { label = mValues.get(val); } else { label = ""; } return label; } }}RESULTHope this helps. 这篇关于如何在 Horizo​​ntalBarChart 中显示右侧的标签和左侧的值?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
