问题描述
我使用的是GraphView图书馆,我不能让图重绘自身时,我更新系列(或者更换一个新的系列)。它似乎只重画自己,当我触摸屏幕。这是我更新功能。
私人无效updateGraph(动物)
{
Toast.makeText(getApplicationContext(),更新图形,Toast.LENGTH_SHORT).show();
GraphViewData [] newData =新GraphViewData [2];
newData [0] =新GraphViewData(0,a.getAvg());
newData [1] =新GraphViewData(1,0.2); GraphViewSeries newSeries =新GraphViewSeries(a.getName(),dStyle,newData); graph.removeSeries(exampleSeries);
graph.addSeries(newSeries);
//更新水平值
//graph.setHorizontalLabels(new的String [] {a.getName()});
}
解决方案
我想它了...
//测试随机的Y值
双RND = generator.nextDouble(); //圆是一个增量值(1,2,3 ...)
GraphViewData newData =新GraphViewData(圆,RND); exampleSeries.appendData(newData,FALSE);
graph.redrawAll();
I am using the GraphView Library and I cant get the graph to redraw itself when I update the series (or replace the series with a new one). It only seems to redraw itself when I touch the screen. Here is my update function.
private void updateGraph(Animal a)
{
Toast.makeText(getApplicationContext(), "Updating Graph", Toast.LENGTH_SHORT).show();
GraphViewData[] newData = new GraphViewData[2];
newData[0] = new GraphViewData(0,a.getAvg());
newData[1] = new GraphViewData(1,0.2);
GraphViewSeries newSeries = new GraphViewSeries(a.getName(),dStyle,newData);
graph.removeSeries(exampleSeries);
graph.addSeries(newSeries);
//update horizontal value
//graph.setHorizontalLabels(new String[]{a.getName()});
}
解决方案
I figured it out...
//test random y value
double rnd = generator.nextDouble();
// round is an incremental value (1,2,3...)
GraphViewData newData = new GraphViewData(round,rnd);
exampleSeries.appendData(newData, false);
graph.redrawAll();
