Applying different colors of color scheme in Charts

Hello Community,

I’m testing the interface designer to setup a dashboard.

My question is, I want to set different colors for each bars.
if i change the color scheme only one color is applied where i want different colors in the color scheme to be applied.
Even if i choose color scheme, it doesn’t change automatically nor by me trying to click each bar and change.

Can anyone give suggestions or advice how to do this?
