[Paraview-developers] Changes coming to ParaView's color legend

[Cory Quammen]

> If it is not trouble, can you make one minor change? Can you make the new color bar a little bit thinner? I think it makes the bar look a bit more slick.

Ken,

Yes, it is very easy to change the default color bar thickness.
Attached is an image with two thinner scalar bars. Which do you
prefer?

Thanks for the suggestion,
Cory
