Conditional colouring

paul_scotchford — Mon, 18 Jul 2016 02:34:26 GMT

I should know the answer to this, but I seem to be having a problem with a solution, basically I have a straight table of only 3 rows, and I want to conditionally colour code (text) the 2nd and 3rd row field 1 based on how they compare to Row 1 field 1 e.g.

Row 1 field 1 stays black,

If Row 2 field 1 is greater than Row 1 field 1 then colour is red , if same then orange else green.

There is a single dimension that is used e.g. Category , so in effect I am testing the values across the dimension rows.

I don' want to write the calculations i.e. the SUM's etc into the colour condition as this becomes clumsy.

Anyone tried this before ? I need an AHA moment

Thanks

Paul

G'day Paul,

I put a flag in the load script and did the comparison there

Load

...

IF( 'row' > PREVIOUS ('row'), 1,0) as myFlag,

....

From

...

order by dimension

then in the chart I put

IF (myFlag = 1, red(), yellow())

cheers,

Write this expression in your Background color

if(Amount = Above(Amount), Yellow(),

if(Amount > above(Amount), Red(), Green()))

No sorry, my point perhaps is not clear, The First Row in the table is what I am comparing my

ROW 2 and ROW 3 against .

Ok here is my solution after a quick walk around the block in the sunshine

if([Avg Cost] < above([Avg Cost],if(RowNo()=3,2,1)),Green(128),

if([Avg Cost] = above([Avg Cost],if(RowNo()=3,2,1)),Yellow(128)

,if([Avg Cost] > above([Avg Cost],if(RowNo()=3,2,1)),Red(128)

,Black()

)))

So Note, My table has only 3 rows and will always be 3 rows.

Got It

if(Amount = above(Amount, RowNo()-1), Yellow(),

if(Amount > above(Amount, RowNo()-1), Red(), Green()))

Missing Manual - FieldValue

This can also reduce effort , check if required.

Hi Paul,

In Text Color option:

You can add an expression like this:

If(IsNull(Above(sum(Value))) = 0,

if(sum(Value) > Above(sum(Value)), red(),

if(sum(Value) = Above(Sum(Value)), RGB(255,128,0), green())), Black())

This expression evaluate the previous value, if it's not null it will check if the current value is greater or equal than the previous and apply the corresponding color code, otherwise font will be black. Here is an example of the output of this function:

Hope it helps.

Yes Agnivesh. That makes it even more simple.

if(Amount = FieldValue('Amount',1), Yellow(),

if(Amount > FieldValue('Amount',1), Red(), Green()))
