Setup your chart as a view within your layout XML

It you're already familiar with with Android's layout xml, then you're all set. Here's an example of how you can embed an XY Chart in your application:

<zeitdata.chart.view.LineChart
  android:id="@+id/myChart"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:padding="5dp"
  zeitdata:chartLabel="Cookie Consumption"
  zeitdata:xAxisLabel="Volume"
  zeitdata:yAxisLabel="Frequency"
  />

Easy to use in code

You can interact with your charts just like any other view in Android. Adding data is easy:

// Create builders for each series to add:
NumericSeries.Builder series1Builder = new NumericSeries.Builder();
series1Builder.withTitle("Number of interviews");
NumericSeries.Builder series2Builder = new NumericSeries.Builder();
series2Builder.withColor(Color.BLUE).withTitle("Job Offers");
// Build points..
NumericPoint point1 = new NumericPoint.Builder(3, 40).build();
// Add points to your series builder: 
NumericSeries interviews = series1Builder.addPoints(point1, ...).build();
NumericSeries jobOffers = series2Builder.addPoints(otherPoint1, ...).build();
// Create a data object with your series and inject into the chart
NumericData.Builder ndb = new NumericData.Builder();
NumericData dataForChart = ndb.addSeries(interviews, jobOffers).build();
LineChart chart = (LineChart) findViewById(R.id.myChart);
chart.setNumericData(dataForChart);

Prototyping is easy!

You can prototype your charts quickly, within your layout preview in Eclipse or IntelliJ by injecting your own sample data too. No more waiting on your emulator:

..
zeitdata:numericDataPrototype="Interviews=[(3,40),(4,12),(6,69),(20,4),(42,15)], Offers=[(1,5),(2,3),(3,2),(4,6),(5,1)]"
..
