I created with Plotchart::createLogXYPlot
in the canvas.
I'm drawing several Graph in same canvas. (Using several plot in same canvas)
I need this canvas to copy or convert file format type.
But I'm searching about this topic, didn't help for me.
Main trouble is saved file having a clipping img.
Clipboard canvas is not working for me. (can't find tag about plotchart)
I'm trying these ways.

.c create rectangle 25 25 50 50 -fill green
raise . ;# if there's anything over the window on-screen, it'll be obscured in the image
update idletasks
image create photo theCanvas -format window -data .c
theCanvas write "C:\\your\\path\\here\\example.png" -format png
