Hello Everyboby: 
        Could I consult everyboby two problems about plot. 
        Recently, I am doing some analysis in plot. 
        Now I can draw boxplot in R , but the result's plot loss some of the x-coordinates. I want to rotate the direction of  x-coordinates' letter so that it can show all. But I don't know how to write this option or function . Or Could you carry out some other good measures to help me?
       The second problem, x-axis in the plot I drawed is time , but the figure in it  is very oddness. For example, the time is 2004-9-29, the figure in the plot is 1095000000.Could anyone help me to settle these problems. 
      Thank you very much! 


Best Regards!
