I am wanting to show a percentage variance on the values I have, but im not sure how best to do this in terms of, do I do this in a table, line chart etc and also, how do I do it? If this is possible, could I please have some guidance on what I need to do roughly to achieve this.
As an example, if I take the number of sales (2020 2,588 v 2019 8,558) I have a difference of 30% and this is what I would like to show
