    I think it is the best way.
    
    Ok, let's explain that my patches is doing.
    
    For example I have time series with history of EUR/USD quotes.
    
    When I upload it to zeppelin, I have line chart below:
    <img width="1199" alt="screen shot 2015-09-18 at 12 14 41" 
src="https://cloud.githubusercontent.com/assets/37775/9955056/e06491f4-5dfe-11e5-99ac-7dd2eb50c548.png";>
    
    The chart looks bad because show zero at Y. And I fix it by my first commit:
    <img width="1204" alt="screen shot 2015-09-18 at 12 15 50" 
src="https://cloud.githubusercontent.com/assets/37775/9955069/098e362a-5dff-11e5-82ee-3c793dc1a802.png";>
    
    The second patch add an extended version of Line Chart that solve problem 
with zoom of chart. For example:
    <img width="1228" alt="screen shot 2015-09-18 at 12 17 11" 
src="https://cloud.githubusercontent.com/assets/37775/9955085/383374f4-5dff-11e5-871b-327a5351b8d8.png";>
