ImageItem drawn on top of plot hides elements of the plot.

[Luka Drmic]

        frame_layout = pg.GraphicsLayout()
        main_subplot = frame_layout.addPlot()
        img = pg.ImageItem()
        img.setImage(self.displayed_data_set, padding=0)

Setting an image item in the plot area with 0 padding hides axis and ticks. Additionaly if grid is turned on it is not visible, as if the image item is "on top" of the plot and it covers all of the elements of the plot item.

If i set the style of ticks to points towards the text, then they are visible, but this is not the behaviour i want.

I have only tried one thing which is

        main_subplot.setZValue(1000)

After that I really had no idea what to try so i came here for help.

Thanks, Luka.

Hi,

I solved this issue with something like this, hopefully it works for you:

self.overview = self.overview_graphicsLayoutWidget.addPlot()
[ self.overview.getAxis(ax).setZValue(10) for ax in self.overview.axes ] # Draw axes and ticks above image/data
