Graph in depth

[mehrdad2000]

Hi please add export depth.
E.g.
Expect to see in single graph:
Time series > analysis > curve fitting > smoothing > algorithm > Exponential smoothing > Holt Winters

But currently show on different graph:
1- Time series > analysis > curve fitting > smoothing
2- smoothing > algorithm > Exponential smoothing > Holt Winters
3- Exponential smoothing > Holt Winters

Thanks
