我使用achartengine在Android应用程序中绘制我的图表，并且条形图有2个问题 .
1：顶部栏中的值不对齐中心
2：图表中仅1 bar时条形图的宽度太小
这是我设置图表的代码
GraphicalView mChart;
// Creating an XYSeries for Income
XYSeries incomeSeries = new XYSeries("\n" + note);
// Adding data to Series
// Arraylist<String> althongtin include input data (some numbers character, eg: {125, 4356, 50000})
for(int i=0;i<althongtin.size();i++){
incomeSeries.add(i, Double.parseDouble(althongtin.get(i)));
}
// Creating a dataset to hold each series
XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
// Adding Income Series to the dataset
dataset.addSeries(incomeSeries);
XYSeriesRenderer incomeRenderer = new XYSeriesRenderer();
incomeRenderer.setColor(color);
incomeRenderer.setChartValuesTextSize(20);
incomeRenderer.setFillPoints(true);
incomeRenderer.setDisplayChartValues(true);
incomeRenderer.setChartValuesTextAlign(Paint.Align.CENTER);
XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer();
multiRenderer.setXLabels(0);
multiRenderer.setChartTitle(ten);
multiRenderer.setXTitle(cotx);
multiRenderer.setYTitle(coty);
multiRenderer.setYLabelsAlign(Paint.Align.LEFT);
multiRenderer.setBarSpacing(1);
multiRenderer.setBarWidth(50);
multiRenderer.setYAxisMin(0);
multiRenderer.setYAxisMax(max + (max/10));
multiRenderer.setXAxisMin(-1);
multiRenderer.setXAxisMax(althongtin.size() + 1);
multiRenderer.setLabelsTextSize(15);
multiRenderer.setLegendTextSize(20);
multiRenderer.setAxisTitleTextSize(20);
multiRenderer.setChartTitleTextSize(20);
multiRenderer.setLabelsColor(Color.BLACK);
multiRenderer.setAxesColor(Color.BLACK);
multiRenderer.setApplyBackgroundColor(true);
multiRenderer.setBackgroundColor(Color.TRANSPARENT);
multiRenderer.setMarginsColor(Color.argb(0,255,255,255));
multiRenderer.setXLabelsColor(Color.BLACK);
multiRenderer.setYLabelsColor(0, Color.BLACK);
multiRenderer.addSeriesRenderer(incomeRenderer);
String[] types = new String[] {BarChart.TYPE};
mChart = (GraphicalView) ChartFactory.getCombinedXYChartView(getBaseContext(), dataset, multiRenderer, types);
multiRenderer.setClickEnabled(true);
multiRenderer.setSelectableBuffer(10);
chartLayout.addView(mChart);
谢谢 .
更新：通过升级到achartengine 1.2.0修复了第二个问题 . 谢谢你，丹 .

对于第一个问题，您可能希望升级到1.2.0每晚构建 .
对于第二个，有：
renderer.setBarWidth(widthInPixels);，因为这是在系列中有一个单项时设置条宽的解决方案 .为什么不使用
ChartFactory.getBarChartView而不是ChartFactory.getCombinedXYChartIntent？我认为这将解决你的问题 .
