Bubble chart transparent bubbles

Mon, 11 Jul 2011 12:50:28 GMT

Hi Everyone,

I have a bubble chart (scatter plot) with different colours for each bubble (this is a requirement). I want to make them solid bubbles but slightly transparent so that overlaps are easily visualised. I can't find an option to do this?

All of my colours are calculated rgb=(xx,xx,xx).

Thanks

Gareth

use argb function instead, works similar with the first parameter being the alpha value (0-255).

Can this work with different colours? I thought it was only possible with a single colour?

Yes, argb() can work with multiple calculated colors, and I've done that on several occasions. It's done like MvanEijk shows, except that the FIRST parameter is the alpha value, not the last.
