Bar graph change colors

[LouisaM]

Is there a way i can set this graph to show diffrent colors based on the values, i.e if the rating is 2 then the color changes to red and if the rating is 3 then the color changes to yellow? 

kindly note that this graph has a filter based on village number

Try going to the series tab and changing bar colors to by category. Then configure the category colors as you like.
