First, thanks a lot for your work.
Legend is not shown properly according to the screenshots I've seen as samples. See screenshort here: http://s22.postimg.org/jw0msxp8x/Screen_Shot005.jpg
Additionally some requests:
* May the names of the X-axis names span two lines. I had to write "S. Galaxy Mini" instead of "Samsung Galaxy Mini" but I'd prefer "SamsungGalaxyMini" for example.
* May you build a horizontal bar chart?
