我在
android上工作achartengine并完成所有的工作我在线图中遇到一个问题我提到了xaxis标签,但它的显示像2,4,6,8,10,12等等与我的xaxis标签覆盖,我想要在xaxis中隐藏2,12个标签.如果你不明白,请参见下图：
这是完整的代码：
public class ChartExample extends Activity {
private GraphicalView mChartView;
XYMultipleSeriesRenderer renderer;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_chart);
LinearLayout layout = (LinearLayout) findViewById(R.id.linearLayout2);
String[] titles = new String[] { "spens1","2second" };
List<double[]> x = new ArrayList<double[]>();
x.add(new double[] { 1,2,3,5,7,9,11,12 });
x.add(new double[] { 1,12 });
// }
List<double[]> values = new ArrayList<double[]>();
values.add(new double[] { 9,15,19,23,26,25,22,18,13,10 });
values.add(new double[] { 11,21,40,12,24,20,12 });
int[] colors = new int[] { Color.BLUE,Color.RED};
PointStyle[] styles = new PointStyle[] { PointStyle.CIRCLE,PointStyle.CIRCLE};
renderer = buildRenderer(colors,styles);
int length = renderer.getSeriesRendererCount();
for (int i = 0; i < length; i++) {
((XYSeriesRenderer) renderer.getSeriesRendererAt(i))
.setFillPoints(true);
}
setChartSettings(renderer,"SCORE CARD VIEW","Attetempts","Marks Scored",12.5,45,Color.LTGRAY,Color.LTGRAY);
renderer.setXLabels(12);
renderer.setYLabels(10);
renderer.setShowGrid(false);
renderer.setXLabelsAlign(Align.CENTER);
renderer.setYLabelsAlign(Align.CENTER);
//renderer.setZoomButtonsVisible(true);
//renderer.setPanLimits(new double[] { 0,40 });
//renderer.setZoomLimits(new double[] { 0,40 });
renderer.setPanEnabled(false,false);
renderer.setZoomEnabled(false,false);
renderer.setShowLegend(false);
for(int k=0;k<12;k++)
{
renderer.addXTextLabel(k+1,"test");
}
if (mChartView == null)
{
Log.d("Oncreate ","if (mChartView == null)");
mChartView = ChartFactory.getLineChartView(this,mDataset(titles,x,values),renderer);
layout.addView(mChartView,new LayoutParams(
LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
}
else
{
mChartView.repaint();
Log.d("Oncreate ","if (mChartView != null)");
}
}
private void setChartSettings(XYMultipleSeriesRenderer renderer3,String title,String xTitle,String yTitle,double xMin,double xMax,double yMin,double yMax,int axesColor,int labelsColor) {
// TODO Auto-generated method stub
renderer3.setChartTitle(title);
renderer3.setXTitle(xTitle);
renderer3.setYTitle(yTitle);
renderer3.setXAxisMin(xMin);
renderer3.setXAxisMax(xMax);
renderer3.setYAxisMin(yMin);
renderer3.setYAxisMax(yMax);
renderer3.setAxesColor(axesColor);
renderer3.setLabelsColor(labelsColor);
}
private XYMultipleSeriesRenderer buildRenderer(int[] colors,PointStyle[] styles) {
// TODO Auto-generated method stub
XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
setRenderer(renderer,colors,styles);
return renderer;
}
private void setRenderer(XYMultipleSeriesRenderer renderer2,int[] colors,PointStyle[] styles) {
// TODO Auto-generated method stub
renderer2.setAxisTitleTextSize(16);
renderer2.setChartTitleTextSize(20);
renderer2.setLabelsTextSize(15);
renderer2.setLegendTextSize(15);
renderer2.setPointSize(5f);
renderer2.setMargins(new int[] { 20,30,20 });
int length = colors.length;
for (int i = 0; i < length; i++) {
XYSeriesRenderer r = new XYSeriesRenderer();
r.setColor(colors[i]);
r.setPointStyle(styles[i]);
renderer2.addSeriesRenderer(r);
}
}
private XYMultipleSeriesDataset mDataset(String[] titles,List<double[]> xValues,List<double[]> yValues) {
// TODO Auto-generated method stub
XYMultipleSeriesDataset dataset1 = new XYMultipleSeriesDataset();
addXYSeries(dataset1,titles,xValues,yValues,0);
return dataset1;
}
private void addXYSeries(XYMultipleSeriesDataset dataset,String[] titles,List<double[]> yValues,int scale) {
// TODO Auto-generated method stub
int length = titles.length;
for (int i = 0; i < length; i++) {
double[] xV = xValues.get(i);
XYSeries series = new XYSeries(titles[i],scale);
double[] yV = yValues.get(i);
int seriesLength = xV.length;
for (int k = 0; k < seriesLength; k++) {
series.add(xV[k],yV[k]);
}
dataset.addSeries(series);
}
}
}
能帮到我了吗？
解决方法
最后我得到了解决方案我已经尝试过以下代码：
renderer.setXLabels(0);
和完整的类代码：
