MPAndroid Chart how to make smooth line chart
I made the smooth line chart this could help the community. Its look like this:
public LineChart lineChartDownFill;
...
private void initLineChartDownFill(View view) {
lineChartDownFill = view.findViewById(R.id.lineChartDownFill);
lineChartDownFill.setTouchEnabled(false);
lineChartDownFill.setDragEnabled(true);
lineChartDownFill.setScaleEnabled(true);
lineChartDownFill.setPinchZoom(false);
lineChartDownFill.setDrawGridBackground(false);
lineChartDownFill.setMaxHighlightDistance(200);
lineChartDownFill.setViewPortOffsets(0, 0, 0, 0);
lineChartDownFillWithData();
}
private void lineChartDownFillWithData() {
Description description = new Description();
description.setText("Days Data");
lineChartDownFill.setDescription(description);
ArrayList<Entry> entryArrayList = new ArrayList<>();
entryArrayList.add(new Entry(0, 60f, "1"));
entryArrayList.add(new Entry(1, 55f, "2"));
entryArrayList.add(new Entry(2, 60f, "3"));
entryArrayList.add(new Entry(3, 40f, "4"));
entryArrayList.add(new Entry(4, 45f, "5"));
entryArrayList.add(new Entry(5, 36f, "6"));
entryArrayList.add(new Entry(6, 30f, "7"));
entryArrayList.add(new Entry(7, 40f, "8"));
entryArrayList.add(new Entry(8, 45f, "9"));
entryArrayList.add(new Entry(9, 60f, "10"));
entryArrayList.add(new Entry(10, 45f, "10"));
entryArrayList.add(new Entry(11, 20f, "10"));
//LineDataSet is the line on the graph
LineDataSet lineDataSet = new LineDataSet(entryArrayList, "This is y bill");
lineDataSet.setLineWidth(5f);
lineDataSet.setColor(Color.GRAY);
lineDataSet.setCircleColorHole(Color.GREEN);
lineDataSet.setCircleColor(R.color.colorWhite);
lineDataSet.setHighLightColor(Color.RED);
lineDataSet.setDrawValues(false);
lineDataSet.setCircleRadius(10f);
lineDataSet.setCircleColor(Color.YELLOW);
//to make the smooth line as the graph is adrapt change so smooth curve
lineDataSet.setMode(LineDataSet.Mode.CUBIC_BEZIER);
//to enable the cubic density : if 1 then it will be sharp curve
lineDataSet.setCubicIntensity(0.2f);
//to fill the below of smooth line in graph
lineDataSet.setDrawFilled(true);
lineDataSet.setFillColor(Color.BLACK);
//set the transparency
lineDataSet.setFillAlpha(80);
//set the gradiant then the above draw fill color will be replace
Drawable drawable = ContextCompat.getDrawable(getContext(), R.drawable.gradiant);
lineDataSet.setFillDrawable(drawable);
//set legend disable or enable to hide {the left down corner name of graph}
Legend legend = lineChartDownFill.getLegend();
legend.setEnabled(false);
//to remove the cricle from the graph
lineDataSet.setDrawCircles(false);
//lineDataSet.setColor(ColorTemplate.COLORFUL_COLORS);
ArrayList<ILineDataSet> iLineDataSetArrayList = new ArrayList<>();
iLineDataSetArrayList.add(lineDataSet);
//LineData is the data accord
LineData lineData = new LineData(iLineDataSetArrayList);
lineData.setValueTextSize(13f);
lineData.setValueTextColor(Color.BLACK);
lineChartDownFill.setData(lineData);
lineChartDownFill.invalidate();
}
MPAndroidChart:v3.0.0-beta1:
lineDataSet.setMode(LineDataSet.Mode.CUBIC_BEZIER);
