Hi, Kumaravel Kulandai Samy !
Thanks for your answer.
The first method with gap seems good, but when I change a data for series and make a few cosmetic changes - the result is as I send in previous message.
The second method not for my case - I need two Y-AXIS.
In attach - my version of solution with changes and result PPT.
What's wrong ? - the series are overlays whith GAP. How I can shift start position of secondary series ?
