I want to display a "Column Range Chart" - a bar chart whose starting point will be variable for each entries, as shown in the below image,

How is it possible to achieve this using MPAndroidChart.

Try with CandleStickChart. It's main purpose it to show financial data. Your problem might be with highest/lowest (shadow) open or closing values, it might require to play with them to achieve what you want.

A quick sample:

CandleStickChart candleStickChart = (CandleStickChart) findViewById(R.id.chart);</p>
ArrayList<CandleEntry> entries = new ArrayList<>
entries.add(new CandleEntry(0, 2.70f, 4.13f, 2.70f, 4.13f));
entries.add(new CandleEntry(1, 3.35f, 4.96f, 3.35f, 4.96f));
entries.add(new CandleEntry(2, 3.50f, 4.50f, 3.50f, 4.50f));
entries.add(new CandleEntry(3, 4.40f, 5.0f, 4.40f, 5.0f));
entries.add(new CandleEntry(4, 2.80f, 4.5f, 2.80f, 4.5f));

Notice that second/fourth third/fifth parameter in CandleEntry constructor are the same to eliminate shadow values.
