Introduction and use of Achartengine (Google's Graphics toolkit for Android)

Achartengine (ACE) is an open source drawing toolkit provided by Google for Android. It integrates the ability to draw multiple graphs: line, scatter, bubble, histogram, pie, gauge, and more. : http://download.csdn.net/detail/u013647453/8511203 (Jar package and development document with 1.1.0) official website: http://code.google.com/p/achartengine (requires a wall-over download)
Below is I developed a simple AndroidStudio1.1 engineering core code: 1, after the establishment of the project, the download Achartengine-1.1.0.jar into the Libs folder, right-click Add as Library. can use the toolkit.
2. You need to include a <activity> node in the <application> node in Androidmanifest.xml, such as: (because, call this package, is implemented by a org.achartengine.GraphicalActivity in a new boot package)

3. Several functions of the Code section: mainly to set some data and graphic colors and other rendering effects

Set the axis name and maximum, minimum tick value, and title name private void Setchart (Xymultipleseriesrenderer renderer) {renderer.setcharttitle ("Algo        Rithm ");        Renderer.setxtitle ("X Axis");        Renderer.setytitle ("Y Axis");        Renderer.setxaxismin (0);        Renderer.setxaxismax (30);        Renderer.setyaxismin (0);    Renderer.setyaxismax (200); }//Set graphics rendering properties Private Xymultipleseriesrenderer Getbarrenderer () {Xymultipleseriesrenderer renderer = new Xymu        Ltipleseriesrenderer ();        Simpleseriesrenderer simpleseriesrenderer = new Simpleseriesrenderer ();        Simpleseriesrenderer.setcolor (color.red);        Renderer.addseriesrenderer (Simpleseriesrenderer);        Simpleseriesrenderer = new Simpleseriesrenderer ();        Simpleseriesrenderer.setcolor (Color.gray);        Renderer.addseriesrenderer (Simpleseriesrenderer);        Setchart (renderer);    return renderer; }//Get DataSet Private Xymultipleseriesdataset Getbardataset () {Xymultipleseriesdataset DataSet= new Xymultipleseriesdataset ();        Random random = new random ();            for (int i = 0; i < 2; i++) {Categoryseries series = new Categoryseries ("algorithm" + (i + 1));            for (int k = 0; k < k++) {Series.add (+ random.nextint ()% 150);        } dataset.addseries (Series.toxyseries ());    } return DataSet; }

Invocation part:

Xymultipleseriesrenderer renderer = Getbarrenderer ();        Intent intents = Chartfactory.getbarchartintent (this, Getbardataset (), renderer, BarChart.Type.DEFAULT);        StartActivity (intents);

Operating effects such as:

See the official development documentation in the download file for more information on how to use it.
