Thread: How to remove QwtPlot grey axes background and shadow?

  1. #1

    Default How to remove QwtPlot grey axes background and shadow?

    I am using QwtPlot to plot a load of polygons, and I want the chart to look just like an image, rather than a chart. I have recently worked out how to remove the grey border behind the axes (A in attachment), and here is the code:

    Qt Code:
    1. //set up QwtPlot
    2. QwtPlot *plot = new QwtPlot;
    3. //this code here changes the axis background from grey to white
    4. QPalette pal = plot->palette();
    5. pal.setColor(QPalette::Window, Qt::white);
    6. plot->setPalette(pal);
    To copy to clipboard, switch view to plain text mode 

    However, I am trying to remove the shadow lines on the top and left of my QwtPlot (B in attachment). Does anyone know how to remove these?

    B) is the frame of the canvas. You can disable it f.e by using QFrame::setFrameStyle(QFrame::NoFrame);

    Hi Uwe,

    Thank you for trying, but I have since worked this out. The solution you gave does not work.

    Here is the solution that works for me:

    Qt Code:
    1. canv.setLineWidth(0);
    2. myPlot->setCanvas(&canv);
    To copy to clipboard, switch view to plain text mode
