SSRS根据单元格值更改填充颜色

Question

I'm aware this has been asked a few times however I'm struggling to find an answer to what I need it for (Or maybe I have missed the answer so please feel free to copy and paste a link if has already been asked)

I'm aware through searching on here the Switch function can help change the colour of the background depending on the value. I have 3 colours needed, however one seems to over ride the other which is causing the issue, and I think this is because one value is in between two numbers

I'm trying to show

Equal or greater than 10 - Red Equal to or greater than 5 until 9.99 - Amber Equal or greater than 0 until 4.99 Green Less than 0 until -4.99 Green -5 until -9.99 Amber -10 or greater Red

I'm using this but it isn't working;

=switch(Fields!Field_Name <= -10, "Red",  
Fields!Field_Name <= -5, "Amber",
Fields!Field_Name >= 10, "Red", 
Fields!Field_Name >= 0, "Green", 
Fields!Field_Name <= 4.99, "Green",
Fields!Field_Name < -0.1, "Green",
Fields!Field_Name <= -4.99, "Green",
Fields!Field_Name > 5, "Amber", True, "Green")

Any help (and not ridicule) would be really appreciated!

Cheers

Answer 1

I find, sometimes it helps to draw out where you want the colours in a range. Then work from outer most conditions inward.

Here's an example of how I would test with a T-SQL CASE expression. I think this logic is what you're after. I've also included an example as an expression.

SQL Example:

WITH
source_data
AS
(
    SELECT tbl.* FROM (VALUES
      ( -11, 'Red')
    , ( 11, 'Red')
    , ( -6, 'DarkOrange')
    , ( 6, 'DarkOrange')
    , ( 1, 'Green')
    , ( 4.98, 'Green')
    , ( -0.11, 'Green')
    ) tbl ([Field_Name], [FillColourWanted]) 
)
SELECT
      [Field_Name] = CAST([Field_Name] AS FLOAT)
    , [FillColourWanted]
    , [FillColour] = 
        CASE 
            WHEN [Field_Name] <= -10 OR [Field_Name] >= 10 THEN 'Red'
            WHEN [Field_Name] <= -5 OR Field_Name >= 5 THEN 'DarkOrange'
            WHEN [Field_Name] < 5 OR [Field_Name] > -5 THEN 'Green'
        END 
FROM
    source_data

SQL Results:

Expression Example:

=Switch(
  Fields!Field_Name.Value <= -10 OR Fields!Field_Name.Value >=10, "Red"
, Fields!Field_Name.Value <= -5 OR Fields!Field_Name.Value >= 5, "DarkOrange"
, Fields!Field_Name.Value > -5 OR Fields!Field_Name.Value < 5, "Green"
)

SSRS Results

The background colour for [FillColourWanted] and [FillColor] are set by the values from the SQL columns. The background colour for [Expression] is set by the expression example.
