ok ya, i may better carry such plattform stuff over to NinjaSupport.
But for who's interested, here my explain. for ur comment b4:
when i hit F, it auto-scales. Meaning the finished bars get longer / shorter all the time.
The visual reference is changing constantly.
With tick chart, the vertical display-distance between the price-entries on the right side of the chart keeps changing ... same thing, visual reference of a steady distance is missing.
Now when the user scales the chart-view vertically, the scale factor of the chart-view remains the same, but if the price is higher or lower than the currently visible range in the chart-window, then the bars / ticks continue outside your viewport (chart-view).
N8 not following centering the data in the visible area of the viewport any more :(
