filled patches in PlotWindow

[kklmn]

Hello silx'ers!

I want to add a collection of rectangular patches to a 1D silx plot, as shown below by the red bands that mark monochromator glitches. I can plot a horizontal segment with addCurve() and fill the rectangle under it by fill=True.

Q1: Is there a simple way to also have the fill above the segment? I would want a band spanning the whole plot height.

Q2: Can a collection of rectangular patches be generated without adding curves?

Thank you in advance!

I got the rectangles by plot.addShape() and setting ± very big y coordinates. And the whole point is that the rectangles do not affect the plot view maximizing. When I need to remove them I do

    for item in plot.getItems():
        if item.getName().startswith('glitch'):  # they were named with legend=f'glitch{ipeak}'
            plot.removeItem(item)

The only thing I can't solve is the forced dotted hatch pattern. I hope you know why you did it.
