change plot and axis background color

[Cal]

Hi,

i couldnt find any hints on how to change the basic layout of the qwt plot. All i want is to change the axis and plot background to a different color and remove the frame border between the axis and the plot.
as far as i understood it i have to change a QwtPlotPrintFilter object.

i tried it with this in the constructor method of my plot class:

QwtPlotPrintFilter filter;
filter.color(Qt::white,QwtPlotPrintFilter::WidgetBackground );
filter.apply(this);
this->replot();

QwtPlotPrintFilter filter;
filter.color(Qt::white,QwtPlotPrintFilter::WidgetBackground );
filter.apply(this);
this->replot();

To copy to clipboard, switch view to plain text mode 

but this doesnt work... maybe someone could help me out here.

thx!

Have you try this method to change the plot background?

plot->setCanvasBackground(QColor(29, 100, 141)); // nice blue
