greater than or less than

LukeCzar — Thu, 01 May 2014 12:21:48 GMT

Good morning,

I would like to use a Rule in which I use different color diagrams base on numbers, so If "something is greater than or less than"

How can I write that code?

For example:

[ATTACH=CONFIG]33525[/ATTACH]
Student hours:

219-1000    red color
1000-2000   yellow color
2000-4000   blue color

I have a code:

case StudentHours > 219 && StudentHours <1000 :
set(material.color.a,0.8)color("#FF0000")
extrude(StudentHours/160)

and it works,

what if I want to show different attributes in diagram? See attachment

hi !

use functions instead, don't write that logic directly in the rules..

e.g.

getColor(value) =
    case value > 2000:
        ""#FF0000""
    case value > 1000:
        "#FF00FF"
    else:
        "#0000FF"

note that this works the same. I used different hex colors here though.

note that if the first case is not true, it goes to the next case, and so on,.. then returns the value.
