HoloGraphLibrary

Fork of the HoloGraphLibrary by Daniel Nadeau, with additionnal features

Welcome

This is a library written to allow beautiful graphs and charts to be easily incorporated into your Android application. Included are:

  • LineGraph view
  • BarGraph view
  • PieGraph view
  • MultiSeriesDonutGraph view

LineGraph BarGraph PieGraph MultiSeriesDonutGraph

Usage

LineGraph View

<com.echo.holographlibrary.LineGraph
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:id="@+id/graph"/>
Line l = new Line();
LinePoint p = new LinePoint();
p.setX(0);
p.setY(5);
l.addPoint(p);
p = new LinePoint();
p.setX(8);
p.setY(8);
l.addPoint(p);
p = new LinePoint();
p.setX(10);
p.setY(4);
l.addPoint(p);
l.setColor(Color.parseColor("#FFBB33"));
		
LineGraph li = (LineGraph)findViewById(R.id.graph);
li.addLine(l);
li.setRangeY(0, 10);
li.setLineToFill(0);

BarGraph View

<com.echo.holographlibrary.BarGraph
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:id="@+id/graph"/>
ArrayList<Bar> points = new ArrayList<Bar>();
Bar d = new Bar();
d.setColor(Color.parseColor("#99CC00"));
d.setName("Test1");
d.setValue(10);
Bar d2 = new Bar();
d2.setColor(Color.parseColor("#FFBB33"));
d2.setName("Test2");
d2.setValue(20);
points.add(d);
points.add(d2);

BarGraph g = (BarGraph)findViewById(R.id.graph);
g.setBars(points);
g.setUnit("$");

PieGraph View

<com.echo.holographlibrary.PieGraph
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:id="@+id/graph"/>
PieGraph pg = (PieGraph)findViewById(R.id.graph);
PieSlice slice = new PieSlice();
slice.setColor(Color.parseColor("#99CC00"));
slice.setValue(2);
pg.addSlice(slice);
slice = new PieSlice();
slice.setColor(Color.parseColor("#FFBB33"));
slice.setValue(3);
pg.addSlice(slice);
slice = new PieSlice();
slice.setColor(Color.parseColor("#AA66CC"));
slice.setValue(8);
pg.addSlice(slice);

#MultiSeriesDonutGraph View

<com.echo.holographlibrary.MultiSeriesDonutGraph
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:id="@+id/graph"/>
MultiSeriesDonutGraph mg = (MultiSeriesDonutGraph) v.findViewById(R.id.multiseriesdonutgraph);

MultiSeriesDonutSlice slice = new MultiSeriesDonutSlice();
slice.setColor(Color.parseColor("#99CC00"));
slice.setValue(2);
mg.addSlice(0, slice);
slice = new MultiSeriesDonutSlice();
slice.setColor(Color.parseColor("#FFBB33"));
slice.setValue(3);
mg.addSlice(0, slice);
slice = new MultiSeriesDonutSlice();
slice.setColor(Color.parseColor("#AA66CC"));
slice.setValue(8);
mg.addSlice(0, slice);

slice = new MultiSeriesDonutSlice();
slice.setColor(Color.parseColor("#99CC00"));
slice.setValue(8);
mg.addSlice(1, slice);
slice = new MultiSeriesDonutSlice();
slice.setColor(Color.parseColor("#FFBB33"));
slice.setValue(5);
mg.addSlice(1, slice);
slice = new MultiSeriesDonutSlice();
slice.setColor(Color.parseColor("#AA66CC"));
slice.setValue(3);
mg.addSlice(1, slice);

Have fun!
