I made a graph with: 
 $image = $mainWindow -> Photo('image2', -file => 'composite.jpeg');
 
 $graph = $mainWindow -> PlotDataset<br>
            (
                #-width => 1304,
                -width => 1304,
                -height => 500,
                -background => 'snow',
                -tile => $image,
                -autoScaleX => "Off",
                -autoScaleY => "Off",
                #-autoScaleY1 => "Off",
            ) -> pack(-fill => 'both', -expand => 1);

Then later I want to replace with the image composite2.jpeg: 

    $image->delete;
    $image = $mainWindow -> Photo('image3', -file => 'composite2.jpeg'
+);
    
    #$mainWindow->configure(-tile => 'image3');
    $graph->configure(-tile => 'image3');

But the old image remains tiled in the background. Is there a way to dynamically replace the tiled image, without recreating the canvas? Or am I approaching the problem wrong? Should I make a frame in the background instead? If so, how would I always keep the frame below my graph canvas?
