First step is top add BarChart view to xml with required width and height. And you can customise the view by parameters.

XML:

<me.ithebk.barchart.BarChart
  android:id="@+id/bar_chart_vertical"
  barchart:bar_type="vertical"
  barchart:bar_width="15dp"
  barchart:bar_color="@color/colorPrimary"
  barchart:bar_text_color="#808080"
  barchart:bar_text_size="10sp"
  barchart:bar_show_auto_color="false"
  barchart:bar_max_value="100"
  barchart:bar_spaces = "0dp"
  barchart:bar_show_value="true"
  barchart:bar_show_animation="true"
  android:layout_width="wrap_content"
  android:layout_height="150dp"/>

Java :

BarChart barChart = (BarChart) findViewById(R.id.bar_chart_vertical);
barChart.setBarMaxValue(100);

ADD BAR:

//Add single bar
BarChartModel barChartModel = new BarChartModel();
barChartModel.setBarValue(50);
barChartModel.setBarColor(Color.parseColor("#9C27B0"));
barChartModel.setBarTag(null); //You can set your own tag to bar model
barChartModel.setBarText("50");

barChart.addBar(barChartModel);

//Add mutliple bar at once as list;
List<BarChartModel> barChartModelList = new ArrayList<>();

//populate bar array list and add to barchart as a list. 
barChart.addBar(barChartModelList);

GET BAR:

//Return value is a list of BarChartModel
barchart.getBar();

//Return value is BarChartModel at that index
barchart.getBar(index);

UPDATE BAR :

BarChartModel barChartModelNew = new BarChartModel();
barChartModelNew.setBarValue(70);
barChartModelNew.setBarColor(Color.parseColor("#CDDC39"));
barChartModelNew.setBarTag(null);
int index = 0;
barChart.updateBar(index,barChartModelNew);

REMOVE BAR :

//To remove BarChartModel object from the list
barChart.removeBar(barChartModel);

//To remove BarChartModel object at the index from the list
barChart.removeBar(index);

ONCLICK LISTENER FOR BAR:

barChart.setOnBarClickListener(new BarChart.OnBarClickListener() {
        @Override
        public void onBarClick(BarChartModel barChartModel) {
            //Returns the bar you have clicked.
        }
    });
