Dimension in Bar Chart

guya — Fri, 04 Jan 2019 13:54:38 GMT

Hi,

I'm trying to reach the following objective:

Table 1

Date	region	count
01/11/2018	region1	100
01/11/2018	region2	20
01/11/2018	region3	30
01/11/2018	region4	15
01/11/2018	region5	20
01/12/2018	region1	40
01/12/2018	region2	50
01/12/2018	region3	20
01/12/2018	region4	30
01/12/2018	region5	60

table2 is a calendar table.

create bar chart for specific month but only 4 regions in the dimension, which are region1, region2, region3&4 and region5. So only one bar for the combined region 3 and 4.

Thanks for the help!

May be use a calculated dimension for this

If(match(region, 'region13, 'region4'), 'region3&4', region)

Like sunny suggested. Doing this in the backend script would be the most efficient (performance) way to go forward; especially if data is big.

But if data size if not a concern; for flexibility front end maybe better. Use valuelist option

Many thx for your prompt reply. Actually I must give more details.

I have region's table like this:

RegionID	Region	Type
1	region1	High
2	region2	High
3	region3	High
4	region4	High
5	region5	High
6	region6	Low
7	region7	Low
8	region8	Low
9	region9	Low

and transactions table:

Date	RegionID	count
01/11/2018	1	100
01/11/2018	2	20
01/11/2018	3	30
01/11/2018	4	15
01/11/2018	5	20
01/12/2018	1	40
01/12/2018	2	50
01/12/2018	3	20
01/12/2018	4	30
01/12/2018	5	60

And the bar chart must only take into account the region where type= 'High', and the dimension must show only 4 high regions where 1 of them is a combination of 2. So dimension should be :

region1 - region2 - region3&4 - region5

Both solutions in the chart or backend script are welcome.

Thx,

Try this

Dimension

=If(Match(Region, 'region3', 'region4'), 'region3&4', Region)

Expression

Sum({<Type = {'High'}>}count)

to get this
