    <p>I am facing with a werid problem. The demos run well, but in my own app, If I switched to another app, and then switched back, there would be an small duplicated chart on the left bottom.</p> <p>The chart in my app will be updated(add new (x,y) and repaint) at intervals.</p> <p>Attached are the original image and image after switched back.</p> <p>I suspect there are some problems with my onResume() method.</p> <pre><code>@Override protected void onResume() { super.onResume(); if (mChartView == null) { LinearLayout layout = (LinearLayout) findViewById(R.id.linearlayout_chart); mChartView = ChartFactory.getLineChartView(this, mDataSet, mRenderer); mRenderer.setClickEnabled(true); mRenderer.setSelectableBuffer(100); mChartView.setOnClickListener(new OnClickListener() { public void onClick(View v) { } }); mChartView.setOnLongClickListener(new OnLongClickListener() { public boolean onLongClick(View v) { return false; } }); mChartView.addZoomListener(new ZoomListener() { public void zoomApplied(ZoomEvent e) { } public void zoomReset() { } }, true, true); mChartView.addPanListener(new PanListener() { public void panApplied() {} }); layout.addView(mChartView, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); } mChartView.repaint(); } </code></pre> <p>I cannot figure out why did this happen, does anyone have the same problem?</p> <p>The normal chart: <img src="https://i.stack.imgur.com/pq0Hs.png" alt="normal chart"></p> <p>After switched back from another app: <img src="https://i.stack.imgur.com/dKTgr.png" alt="enter image description here"></p> <p>Android 3.2 (API Level 13) AChartEngine version 0.7.0 Asus EEE pad</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
