dependencies 
    implementation 'com.github.PhilJay:MPAndroidChart:v3.1.0' // Change with the most recent model

After syncing your challenge, you can begin utilizing the library in your actions or fragments.

2. Primary Chart Implementation (Line Chart Instance):

LineChart lineChart = findViewById(R.id.lineChart);

LineData lineData = new LineData();
lineChart.setData(lineData);

// Add knowledge factors
Checklist<Entry> entries = new ArrayList<>();
entries.add(new Entry(1, 10));
entries.add(new Entry(2, 15));
entries.add(new Entry(3, 12));

LineDataSet dataSet = new LineDataSet(entries, "Knowledge Set 1");
lineData.addDataSet(dataSet);

lineChart.invalidate(); // Refresh the chart

This code snippet creates a fundamental line chart with three knowledge factors. You may want to exchange R.id.lineChart with the ID of your LineChart view in your XML format file.

3. Customization:

MPAndroidChart presents in depth customization choices:

• Knowledge Look: You possibly can customise the colour, form, and dimension of information factors, traces, and bars.
• Axes: Management the axis labels, grid traces, and their ranges.
• Labels and Legends: Customise the textual content and look of labels and legends.

Add AndroidPlot as a dependency to your construct.gradle file:

dependencies 
    implementation 'com.androidplot:androidplot-core:1.6.0' // Change with the most recent model

2. Primary Chart Implementation (XYPlot Instance):

XYPlot plot = findViewById(R.id.mySimpleXYPlot);

Quantity[] series1Numbers = 1, 2, 3, 4, 5;
Quantity[] series2Numbers = 10, 15, 12, 18, 20;

XYSeries series1 = new SimpleXYSeries(Arrays.asList(series1Numbers), SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Sequence 1");
XYSeries series2 = new SimpleXYSeries(Arrays.asList(series2Numbers), SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Sequence 2");

LineAndPointFormatter series1Format = new LineAndPointFormatter(Shade.RED, Shade.GREEN, null, null);
LineAndPointFormatter series2Format = new LineAndPointFormatter(Shade.BLUE, Shade.YELLOW, null, null);

plot.addSeries(series1, series1Format);
plot.addSeries(series2, series2Format);

plot.redraw();

This creates a easy XYPlot with two knowledge sequence. Once more, you may must have a corresponding XYPlot view in your format XML.
