Android: I am using AChartEngine library for graphs, but not able to integrate achartengine’s graph view with android xml?

by

This is a FAQ for AChartEngine.
The AChartEngine demo application is available for download here: AChartEngine demo

In the demo source code you can see an example on how to embed a chart into an existing view.

Basically, in the activity descriptor .xml file, we have defined the following as a placeholder for the chart. Of course, other user interface components go together with this layout:

ChartDemo/layout/xy_chart.xml near Line 27

<LinearLayout
    android:id="@+id/chart"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:orientation="horizontal" />

We define a local variable:

ChartDemo/src/org.achartengine.chartdemo.demo.chart/XYChartBuilder.java near Line 68

private GraphicalView mChartView;

We instantiate it on the onResume() method of the activity:

ChartDemo/src/org.achartengine.chartdemo.demo.chart/XYChartBuilder.java near Line 163

protected void onResume() {
  super.onResume();
  if (mChartView == null) {
    LinearLayout layout = (LinearLayout) findViewById(R.id.chart);
    mChartView = ChartFactory.getLineChartView(this, mDataset,
mRenderer);
    layout.addView(mChartView, new LayoutParams
(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    ...
  } else {
    mChartView.repaint();
  }
}

Whenever new data is added (when the user presses the “Add” button in our case, a new point is added in the current series and:

ChartDemo/src/org.achartengine.chartdemo.demo.chart/XYChartBuilder.java near Line 147

if (mChartView != null) {
  mChartView.repaint();
}
