Formatting Charts

Hello,

I would like to know if it’s possible to format the chart which I have attached. The chart area is too small and I'm trying to get it to fit the screen as the legend on the side is not showing labels completely. I wonder if this is possible. Also whether it would be possible to amend the data labels on the chart to have either % or the word days at the end of the value.

It is based off of figures on another table and the values are percentages and numbers.

Hope this makes sense, if not please let me know.

Any help appreciated, thanks in advance.
