Axis yLeft cuts of numbers

[sun]

Hi,

I use a manually settable Y Axis on my custom QwtPlot.
It now sometimes occurs, that the values shown on the left arr cut at the beginning.
so 10000000 will be shown okay, because it takes the place it needs from the plot,
but 60000 or bigger (5,6,4) numbers will be cut of some pixels on the left.

Is this a Layout problem or is there something I have to do with qwt?

Thanks!
