I have a chart with prices of multiple stocks.
The problem is that some prices are below 100 while others are above 1000, so the chart is really ugly.
How do I compare historical in multiple stocks, so the chart is still readable. For instace, if I add Berkshire Hathaway, I won't be able to read anything off my chart because of the large gap between prices of different stocks.
I wonder if that's what the logarithmic scale is for?
This is precisely the idea behind having one axis using a logarithmic scale. It is always a good idea to use this if the data varies over more than an order of magnitude.
