AutoGen_6274018 Posts: 2 Rating: (0)	what I meant is by using curveFilled(), i am able to fill the area of the curve with a color , this works with value over time trend. The same is not working for value over value trend. Can you please suggest me some alternate to fill the area of the curve for a value over value trend
