I'm using AChartEngine to display averages across several days (2 months if possible). I'd like to provide a comparison between one individual and a group. At this point, I'm working on how to provide dates across the x-axis (ie, 12/15/2011 or Dec. 11, 2011 or even 12/15, Dec. 15).
我使用AChartEngine来显示数天的平均值(如果可能的话)。我想提供一个个体和一个群体的比较。在这一点上，我正在研究如何在x轴上提供日期(例如，2011年12月15日或2011年12月11日，甚至12月15日，12月15日)。
I'm not sure how to do this in AchartEngine; the documentation is a little hard for me to follow without pictures (sorry). I'd like something like this: Using AChartEngine library for graphs, not able to get value for diffrent x-axis value
我不知道如何在阿切尔腾内做这个;对于我来说，没有图片(抱歉)，文档是有点困难。我想要这样的东西:使用AChartEngine函数库来绘制图形，不能得到不同的x轴值。
Here's my code:
这是我的代码:
private void setupHistoryChart() {
XYMultipleSeriesRenderer renderer = getBarDemoRenderer();
setChartSettings(renderer);
Intent intent = ChartFactory.getBarChartIntent(this, getBarDemoDataset(), renderer, Type.DEFAULT);
startActivity(intent);
}
public XYMultipleSeriesRenderer getBarDemoRenderer() {
XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
renderer.setAxisTitleTextSize(15);
renderer.setChartTitleTextSize(18);
renderer.setLabelsTextSize(12);
renderer.setLegendTextSize(15);
renderer.setMargins(new int[] {20, 30, 15, 0});
SimpleSeriesRenderer r = new SimpleSeriesRenderer();
r.setColor(Color.BLUE);
renderer.addSeriesRenderer(r);
return renderer;
}
private void setChartSettings(XYMultipleSeriesRenderer renderer) {
renderer.setChartTitle("History");
renderer.setChartTitleTextSize((float) 14.0);
renderer.setXTitle("Day");
renderer.setXLabelsAlign(Align.LEFT);
renderer.setYLabelsAlign(Align.LEFT);
renderer.setBarSpacing(0.5);
renderer.setZoomEnabled(true);
renderer.setZoomRate(0.2f);
renderer.setYTitle("Unit)");
renderer.setXAxisMin(1.0);
if(AppStatus.mDayMap.size() == 0){
renderer.setXAxisMax(3.0);
renderer.setYAxisMax(10.0);
}else{
renderer.setXAxisMax(AppStatus.mDayMap.size());
// Get the max Integer out of myMap
Map.Entry<String, Integer> maxEntry = null;
for (Map.Entry<String, Integer> entry : AppStatus.mDayMap.entrySet())
{
if (maxEntry == null || entry.getValue().compareTo(maxEntry.getValue()) > 0)
{
maxEntry = entry;
}
}
renderer.setYAxisMax(maxEntry.getValue()/1000 + maxEntry.getValue()/1000);
}
renderer.setYAxisMin(0);
}
private XYMultipleSeriesDataset getBarDemoDataset() {
XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
HashMap<String, Integer> myMap = AppStatus.mDayMap;
CategorySeries series = new CategorySeries ("Your History " + 1);
try{
if(AppStatus.mDayMap.size() == 0){
series.add(3.0);
series.add(10.0);
dataset.addSeries(series.toXYSeries());
}else{
Log.v(LOG_TAG, "Size of Map = " + myMap.size());
float sum = (float) 0.0;
if(myMap.size() > 0){
Iterator it = myMap.entrySet().iterator();
float j= (float)0.0;
for (int i = 0; i < 1 /*2*/; i++) {
//CategorySeries series = new CategorySeries("Your History " + (i + 1));
while(it.hasNext()){
Map.Entry pairs = (Map.Entry)it.next();
sum = sum + (float) (1.0 + j);
series.add((((Integer) pairs.getValue()).doubleValue())/1000);
}
dataset.addSeries(series.toXYSeries());
}
}
}
}catch(IllegalArgumentException e){
Log.e(LOG_TAG, "IllegalArgumentException " + e.toString());
series.add(3.0);
series.add(10.0);
dataset.addSeries(series.toXYSeries());
}
return dataset;
}

You can set custom text for the X axis labels:
您可以为X轴标签设置自定义文本:
renderer.addXTextLabel(x, text);
renderer.setXLabels(0);
In order to have multiple color bars in the bar chart, you will have to add multiple series.
为了在条形图中有多个颜色条，您需要添加多个系列。
There are some instructions here on how to download and run the demo application which includes a lot of good code to demonstrate the AChartEngine usage.
