# Imshow figure whitespace reduction

Hello,

Can anyone tell me how to reduce the whitespace between the color bar and heatmap, generated with `px.imshow` and indicated in the plot below with an arrow? I’d rather not use `aspect = 'auto'` as I quite like the square layout, so I’d rather just shift the color bar to the right. I’ve tried the code below but it didn’t work:

``````figure_test.update_layout(
margin=dict(l=20, r=200, t=20, b=20),
)
``````

Many thanks,
Tim
