Hello Arima,
Unfortunately there is no way out-of-the-box to change the position of the XAxis. Positioning MarkedZone at Yvalue = 100 could be helpful but this way you won't be able to show all of the Labels that you have on the picture (the months).
I would suggest that you leave the Chart with the default position of the XAxis so that you keep the Axis Items labels.
