I am using Google's visualization API for drawing charts that show files downloaded each day.
I don't know if this is the best idea, but I am thinking of showing download counts on the Y-axis, weekdays (Monday, Tuesday, etc.) on the X-axis, while the legend would show the name of the files. I am facing a problem when the names/legend of files goes out of bound which makes the bars too close and confused even with color variations.
So, what alternative visualization technique might be applied in this case?
