Color code rows in dimension value

blaise — Wed, 12 Dec 2012 15:48:08 GMT

Hello

I would like to color code the background of the dimension values in a straight table, somewhat like the "strip every" function but for every new value. With the following example table;

Dimension1	Dimension2	Expression
A	1
A	2
A	3
B	1
B	2
C	1
D	1
D	2
D	3
D	4

I would like the background color of Dimension1 to be grey for the values A, white for B, grey for C, white for D and so on.

Is this possible? I have tried with the above() function but that doesn't seems to do the trick. The values of Dimension1 in the real data is not as simple as A-Z.

You can click on the '+' symbol next to your dimension and there under 'background' option, you can write a if statement to derive the color you want.

I hope this helps.

Hi,

This should do the trick :

Background Color expression for Dimension1 :

=if(even(aggr(NODISTINCT rowno(),Dimension1)),rgb(180,180,180),white())

Regards,

Thomas

Yea, I know how to change the background color of the cell - the question I asked was how to give the the Dimension1 value A and C the same bg color, and B and D another bgcolor.

We're getting close, thanks Thomas. However it looks like i need to combine some sort of sort with the aggr() function, as of now the first set of dimension1 values in the straight table doesn't get the number 1, and the second set of values doesn't get the number 2.

Yes, you're right, rowno() order seems to be inverted (max value for first dimension value).

That's start to become tricky, but i think the following expression could make it :

=if(even(aggr(NODISTINCT GetPossibleCount(Dim1) - rowno(),Dim1)),white(),rgb(180,180,180))

Well im my test app the "sort order" is somewhat fucked - i could live with an inverted sort order but not with the an "unknown order".

Attached the test app.

Yea, rowno() seems to use kind of fieldindex values, we cannot sort them.

I've changed my mind, so, last try...

With a variable : vTEST = concat(DISTINCT TOTAL {<Dim2-={"$(=null())"}>} chr(39)&Dim2&chr(39),',') //Need to remove null values, don't know why

and as color expression : =if(even(match(Dim2,$(vTEST))),white(),rgb(200,200,200))

Hope this one will be the good one...

Hi Blaise,

There is a function called HSL(Hue,Saturation,lum) where we can pass the values from 0 to 1.

If you are going to generate one unique HSL for each distinct value of Dim1, you can use the value in Background colour.

Here is the sample code that i attached. Please reply back if it works.

Hi Blaise, Please find the attched file and hope it helps very well.

I don't want unique color for every value

Re: Color code rows in dimension value

blaise — Wed, 12 Dec 2012 18:58:42 GMT

It works with no selection, but if you for example select Dim2 = A,C then all rows are grey. I don't think it can be solved in the script.

I've tried it but sadly it doesn't work. Will try more with the aggr(), match() and concat() function though...

I defined the coulr for each value ofDim1 in the Script. So you selected any thing, automatically selection made.

Hi blaise, please try this: 1. open the table property window 2. select the dimension tab 3. click the plus (+) sign on the left of the dimension to fill with different colour 4. double click on background colour 5. enter your conditional fill expression [eg. =if(Dimension1 like 'A*',QlikTechBlue(),if(Dimension1 like 'B*',QlikTechGray(),Green())) ] 6. confirm changes Regards Andrea

doesn't solve my problem. I don't want to hard code colors to each dimensions.

is it possible for you to store the color (RGB combination) as part of your table? If YES, then in your table itself you can define which color you want for each dimension value (A, B, C etc..).

Then you can use the RGB values in your table object to define the color of the cell based on cell value.

Hi Blaise,

My last proposition is working weel i think, see attachement.

3 remarks :

- Don't forget the "=" sign before the variable expression

- if you have "set analysis" in the expressions of your table that could reduce the values of Dim2, use the same SET in the concat function of the variable

- The sort order of Dim2 must be fixed. If it's not sorted alphabeticaly, you can also define a custom sort order in the concat function

Good luck,

Thomas

Yes indeed, it works!

I would rather not have a variable that is calculated for every selection, but it might be that this is the only available solution .

Thanks for all your help

Hi blaise, try putting the following expression in the color property of the dimension: =if(Mod(FieldIndex('Dimension1',Dimension1),2)=1,QlikTechGray(),White()) Regards AL
