Combo chart with cumulative

[Anonymous]

Hi all. Hopefully this is pretty straight forward.

So here is the script I have for my app:

SELECT

True_Churn, Retention_Target, Date_Measure, Closing_Base, Opening_Base,

(Closing_Base - Opening_Base) as Flow

from xxxxx

And here is my data table:

Opening_Base	Closing_Base	True_Churn	Retention_Target	Date_Measure
40335	40838	7	88.50%	01-01-18
40838	44219	549	85.90%	01-02-18

Each month I'm going to update the table with the previous month's data.

I want to product a combo bar/line graph showing each month's Flow number as the bars, with the cumulative month on month Flow as the line.

The basics are pretty, well, basic:

• Dimension = month(Date_Measure)
• First measure for the bars = sum(Flow)

But how do I add a cumulative line graph to it please?

I have tried

if(Sum(if(year(Date_Measure)=2018, Flow,0))>0,  rangesum( above( sum(if(year(Date_Measure) = 2018,Flow,0)),0,rowno())), null)

But it's returning a figure for Feb of 27,188 (no idea how it's got that) not the expected 3,884.

Hi,

can you attach some data ? 12 lines with 2 columns: Flow and Date_measure

Hi Youssef

As attached - it's my actual data. Thanks!

Hi - sorted. I had made it far too complicated. Just a straight

Rangesum(above(sum(Flow),0,RowNo()))

Has done it.
