- Line Charts
- Bar Charts
Tested on Android 1.6, 2.2, 2.3 and 3.0 (honeycomb, tablet), 4.0.
- Two chart types Line Chart and Bar Chart.
- Draw multiple series of data Let the diagram show more that one series in a graph. You can set a color and a description for every series.
- Show legend A legend can be displayed inline the chart. You can set the width and the vertical align (top, middle, bottom).
- Custom labels The labels for the x- and y-axis are generated automatically. But you can set your own labels, Strings are possible.
- Handle incomplete data It's possible to give the data in different frequency.
- Viewport You can limit the viewport so that only a part of the data will be displayed.
- Scrolling You can scroll with a finger touch move gesture.
- Scaling / Zooming Since Android 2.3! With two-fingers touch scale gesture (Multi-touch), the viewport can be changed.
- Background (line graph) Optionally draws a light background under the diagram stroke.
- Manual Y axis limits
- Realtime Graph (Live)
Very simple example:
// init example series data
GraphViewSeries exampleSeries = new GraphViewSeries(new GraphViewData[] {
new GraphViewData(1, 2.0d)
, new GraphViewData(2, 1.5d)
, new GraphViewData(3, 2.5d)
, new GraphViewData(4, 1.0d)
});
GraphView graphView = new LineGraphView(
this // context
, "GraphViewDemo" // heading
);
graphView.addSeries(exampleSeries); // data
LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
layout.addView(graphView);
