In edit view you can change all elements in your chart including font size used in title, axes and at end of each bar (too big in my opinion.
That chart space will automatically resize as you do so.
You can also modify the overall size of the chart area by grabbing the border and dragging.
With a bit of tweaking you should get your desired result.
Ok, finally figured it out.
1)Change the size of the font.
2)Resize the bar part of the graph as far left as possible
3)???
4)The graph autosizes and the words finally fit.
