I have to plot two different dataSets in a single graph.
DataSet-1
String[] xAxisOne = new String[] {
"0", "1", "2", "3", "4", "5", "6"
};
float[] dataInput = {
1f, 2f, 3f, 4f, 5f, 6f, 7f
};
DataSet-2
String[] xAxisTwo = new String[] {
"0", "2", "4", "5", "6", "8", "9"
};
float[] dataIn = {
3f, 4f, 5f, 6f, 7f, 8f, 9f
};
In the above data, DataSet-1 is reference by which graph is created. DataSet-2 has to be plotted in the same with different set of X-Values {xAxisTwo}.
In existing Implementation, first 6 values {dataInput} are plotted & next 6 values {dataIn} are plotted with reference to xAxisOne
, How to plot as required.
Well this will need an update as of version 3:
For multiple lines , you will need multiple datasets. Assuming you have created two data sets.
LineDataSet dataSetReported = new LineDataSet(entriesReported, "Reported");
LineDataSet dataSetCalculated = new LineDataSet(entriesCalculated, "Calculated");
You will need a list of ILINEDATASET to accommodate both datasets created. Simply create a list and add datasets.
List<ILineDataSet> lines = new ArrayList<ILineDataSet>();
lines.add(dataSetReported);
lines.add(dataSetCalculated);
Display it on chart as:
LineData data = new LineData(lines);
chart.setData(data);
chart.invalidate();
Refer here for documentation from original author.
You can do this with LineChart and unifying the xAxis and ignoring the "null" point for each dataset. See the code below:
//float[] dataInput = {
// 1f, 2f, 3f, 4f, 5f, 6f, 7f
//};
//values for datainput Dataset1 at your axisone positions
ArrayList<Entry> dataset1 = new ArrayList<Entry>();
dataset1.add(new Entry(1f, 0));
dataset1.add(new Entry(2f, 1));
dataset1.add(new Entry(3f, 2));
dataset1.add(new Entry(4f, 3));
dataset1.add(new Entry(5f, 4));
dataset1.add(new Entry(6f, 5));
dataset1.add(new Entry(7f, 6));
//float[] dataIn = {
// 3f, 4f, 5f, 6f, 7f, 8f, 9f
//};
//values for datainput Dataset2 at your axisone positions
ArrayList<Entry> dataset2 = new ArrayList<Entry>();
dataset2.add(new Entry(3f, 0));
dataset2.add(new Entry(4f, 2));
dataset2.add(new Entry(5f, 4));
dataset2.add(new Entry(6f, 5));
dataset2.add(new Entry(7f, 6));
dataset2.add(new Entry(8f, 7));
dataset2.add(new Entry(9f, 8));
//String[] xAxisOne = new String[] {
// "0", "1", "2", "3", "4", "5", "6"
//};
///String[] xAxisTwo = new String[] {
/// "0", "2", "4", "5", "6", "8", "9"
///};
// Union from xAxisOne and xAxisTwo
String[] xAxis = new String[] {"0", "1", "2", "3", "4", "5", "6", "8", "9"};
ArrayList<LineDataSet> lines = new ArrayList<LineDataSet> ();
LineDataSet lDataSet1 = new LineDataSet(dataset1, "DataSet1");
lDataSet1.setColor(Color.RED);
lDataSet1.setCircleColor(Color.RED);
lines.add(lDataSet1);
lines.add(new LineDataSet(dataset2, "DataSet2"));
LineChart chart = (LineChart) getView().findViewById(R.id.chart);
chart.setData(new LineData(xAxis, lines));
The final result will be:
Looks that the red line of dataset1 have 2 more points than blue line. If the dataset1 have only these two points(at position 1 and 3) like this:
ArrayList<Entry> dataset1 = new ArrayList<Entry>();
dataset1.add(new Entry(2f, 1));
dataset1.add(new Entry(4f, 3));
it will be the result:
you can use this Line Chart passing multiple Data Set
LineChart lineChart1 = (LineChart) findViewById(R.id.chart1);
ArrayList<Entry> entries = new ArrayList<>();
entries.add(new Entry(4f, 0));
entries.add(new Entry(8f, 1));
entries.add(new Entry(6f, 2));
entries.add(new Entry(10f, 3));
entries.add(new Entry(18f, 4));
entries.add(new Entry(9f, 5));
ArrayList<Entry> entry = new ArrayList<>();
entry.add(new Entry(3f, 0));
entry.add(new Entry(10f, 1));
entry.add(new Entry(4f, 2));
entry.add(new Entry(14f, 3));
entry.add(new Entry(12f, 4));
entry.add(new Entry(5f, 5));
ArrayList<LineDataSet> lines = new ArrayList<LineDataSet> ();
String[] xAxis = new String[] {"1", "2", "3", "4", "5","6"};
LineDataSet lDataSet1 = new LineDataSet(entries, "DataSet1");
lDataSet1.setDrawFilled(true);
lines.add(lDataSet1);
LineDataSet lDataSet2 = new LineDataSet(entry, "DataSet2");
lDataSet2.setDrawFilled(true);
lines.add(lDataSet2);
lineChart1.setData(new LineData(xAxis, lines));
lineChart1.animateY(5000);
}
