QCPAxis while lineReturn to overview

Hello,
I have a plot https://i.imgur.com/m5Sf3e8.png
I don't need axes, tickers. So I disable them with following code:

    axisRect()->setAutoMargins(QCP::msNone);
    xAxis->setTicks(false);
    yAxis->setTicks(false);
    xAxis->setBasePen(QPen(Qt::NoPen));
    yAxis->setBasePen(QPen(Qt::NoPen));

Result is this https://i.imgur.com/4ldel81.png.
And that is pretty much what I want but if one looks closely there is single pixel white line at the bottom and left sides where the QCPAxis have been.

forgot my question...
How to remove while lines?
