ChartJS large data range - chart.js

Question

I have a dataset which has large range between the largest and the smallest. My problem is that the smallest bar becomes invisible when the largest bar has too much data. Take a look at the screenshot below.
In the screenshot, the second, third, fifth and sixth bars all have one data point but they are being invisible. So my question is,
1) Is there anyway to make small data point visible for bar chart such as by setting min-height property on them?
2) If not, how can I make the chart so that hovering works on whole y-axis for a particular bar when the data is too small so that when I hover over the y-axis it shows label with data?
I've tried setting different styles on the bars to no avail.

Since you haven't provided your code, I can only tell you to use a logarithmic scale for your chart.
See this example for reference:
var dataPoints = [
{ x: 1994, y: 25437639 },
{ x: 1995, y: 44866595 },
{ x: 1996, y: 77583866 },
{ x: 1997, y: 120992212 },
{ x: 1998, y: 188507628 },
{ x: 1999, y: 281537652 },
{ x: 2000, y: 414794957 },
{ x: 2001, y: 502292245 },
{ x: 2002, y: 665065014 },
{ x: 2003, y: 781435983 },
{ x: 2004, y: 913327771 },
{ x: 2005, y: 1030101289 },
{ x: 2006, y: 1162916818 },
{ x: 2007, y: 1373226988 },
{ x: 2008, y: 1575067520 },
{ x: 2009, y: 1766403814 },
{ x: 2010, y: 2023202974 },
{ x: 2011, y: 2231957359 },
{ x: 2012, y: 2494736248 },
{ x: 2013, y: 2728428107 },
{ x: 2014, y: 2956385569 },
{ x: 2015, y: 3185996155 },
{ x: 2016, y: 3424971237 }
