title: Trying to set a minimum height on bars in HighStock
body: <p><img src="https://i.stack.imgur.com/U5FEV.png" alt="enter image description here">We're working on a project that charts the sales per country for two groups. The challenge is that since our prototype is focused on the US the sales in the US always dwarf all other countries. What we'd like to do is set a minimum height for any bar that is >0 so that the user will be able to see all the bars and know to mouse over for the count on the hover state.</p>
  
  <p>I've attached an image to show how the scale of the sales in the US makes the sales in the countries to the right look like 0. In most cases only the US appears but we never show a country along the bottom unless there is at least 1 sale.</p>
  
  <p>Anyway to define a minimum height so that there is always some bar present? We tried adding a border but that didn't work in the case where there was such a small # of sales relative to the large bar.</p>
  
  <p>Thanks!</p>
