How to add a right margin to the QWT plot canvas?

[brianbat]

Hello,

Can someone tell me how to add a right margin to the QWT plot canvas? I have a continuous curve plotting, such as an oscilloscope, and the curve currently goes all the way over to the right side. I would like a margin inserted on the right side so there is blank space between the end of the curve and the right border on the canvas.

Thanks.

What about

plot->plotLayout()->setCanvasMargin( 20, QwtPlot::yRight() );

plot->plotLayout()->setCanvasMargin( 20, QwtPlot::yRight() );

To copy to clipboard, switch view to plain text mode 

You could also add some offset to the x scale, so that its upper limit is always ahead of the x value of the current sample.
