Changing line chart expression colour

Wed, 25 Nov 2020 16:16:04 GMT

I have a line chart with some expressions. Now I am trying to change the colour of an expression through its background colour property by assigning a variable which is a colour but it is not working.

For example, I create a variable called "expr1_color" as below:

RGB(153,204,255)

then I assign this variable to the expression background colour property in definition field as below:

expr1_color

but it is not woking: expression colour remains the same in the chart despite I change it and in the legend, color for this expression is not displayed (no color is displayed).

Use

=$(expr1_color)

Hi Tony, can you try this:

$(expr1_color)

$() = This is called $-expansion, it converts the content before the expression calculation, so

$(expr1_color) --> is converted to --> RGB(153,204,255)
