我正在使用Android应用程序，并且有一个传感器读数图：在Y轴上绘制了温度/湿度/风，然后在X轴上绘制了时间/日期。我正在使用SimpleGraph library。在大多数情况下，一切都很好。但是，我遇到了2-3个问题。
graph.getViewport().scrollToEnd();，则没有任何变化。 所以我知道我得到了正确的数据点，因为我的日志显示了它们。我很确定它们不会被视线绘制出来。我真正想要的是弄清楚如何根据时间选择正确获取数据和标签。例如日/周/月。我已经包括了两个主要的类，以及一个针对3标签调用的示例调用。
我可能缺少一些简单的东西。感谢任何建议，评论。
谢谢！
从主屏幕调用并指定标签计数：
graphTemp = (GraphView) findViewById(R.id.graphTemp);
try {
GraphUtility gu = new GraphUtility(1,1,3,true,false, this,celsius);
gu.grapher( this,graphTemp, gu.seriesBuilder(
gu.getTempData(gu.getSixHours())));
这是我要设置简单图形的地方：

答案 0 :(得分：0)
好吧，像往常一样，在决定发布之后，我能够借助simplegraphs doc上的示例来制定解决方案。我以为我从文档中镜像了日期示例，但是我省略了一个关键部分：
// set manual x bounds to have nice steps
graph.getViewport().setMinX(start);
graph.getViewport().setMaxX(System.currentTimeMillis());
graph.getViewport().setXAxisBoundsManual(true);
由于某种原因，尽管使用了API中提供的清除/重置功能，但我仍无法正确清除每个图形的样式/数据。为了避免浪费太多的时间，我决定在布局中创建三个graphview，然后隐藏不使用的graphview。这不是最佳方法，但似乎不会影响性能。有关代码更改，请参见下文。请注意，出于风格原因进行了一些更改。
我将我的绘图器方法更改为包括双开始，这是从此处开始的时间：
Class GraphUtility

graph.removeAllSeries();
graph.getGridLabelRenderer().resetStyles();

if(focus==0) {
for (int i = 0; i < seriesArray.length; i++) {
// series = new LineGraphSeries();
series = seriesArray[i];
series.setDrawBackground(true);
if (i == 0) {
series.setColor(Color.parseColor("#8d1007"));
series.setBackgroundColor(Color.parseColor("#4D6a0c05"));
}
if (i == 1) {
series.setColor(Color.parseColor("#00004C"));
series.setBackgroundColor(Color.parseColor("#4D00004C"));
}
if (i == 2) {
series.setColor(Color.parseColor("#006600"));
series.setBackgroundColor(Color.parseColor("#4D006600"));
}
series.setDataPointsRadius(4);
series.setThickness(4);
graph.getGridLabelRenderer().setGridColor(graphColor);
graph.getGridLabelRenderer().setHorizontalLabelsColor(graphColor);
graph.getGridLabelRenderer().setVerticalLabelsColor(graphColor);
graph.addSeries(series);
}
}
if(focus == 1){
