rgb code and brightness

stekol61 — Thu, 24 May 2018 10:41:17 GMT

I have set the a bar color using the 'Background color' for an expression. I use rgb(216,207,39).

In the Chart Properties I can do the same using Colors - Data Appearance and customize e.g. Colour1 using the same rgb code.

The problem is that when using Colors - Data Appearance I've adjusted the Brightness for the color.

Is it possible to do the same when using 'Background color' for an expression?

You could try it with argb() or one of the colormix-functions.

As far as I know, the Brightness slider only becomes active if you select a "Single Color Gradient" instead of a fixed or a calculated color. The Brightness value determines to what same-color brightness the gradient will evolve. You can only set the Brightness-level itself in the color dialogs that have this slider.

There are no corresponding functions in QlikView that offer a single-color gradient with a Brightness setting. But you can set the "brightness" of a single specific color (i.e. not a gradient) by manipulating the luminosity parameter in a HSL() function call.
