Rank function reverse axis on chart

[sifatnabil]

Hi,

I have a chart which shows the rank by week of clients, from 1 to 10, using the rank() function. The top ranked client is obviously ranked 1, but this shows at the bottom of the chart (since it's a value of 1). How can I reverse the dimension axis so that Rank 1 is shown on top and Rank 10 shown at the bottom? Chart below:
