Cumulative count over time
Hey,
I need to standardize my data. I get at irregular intervals a value for my devices. Message is sent when status changes. Here is an example data and what I mean by standardizing. In this example is to convert time to 10min sections.
| 10A | Time | 10:11 | 10:14 | 10:18 | 10:48 | |||
| Value | 1 | 0 | 1 | 0 | ||||
| 20B | Time | 10:18 | 10:34 | 10:51 | ||||
| Value | 0 | 1 | 0 | |||||
| Would look like this if "cumulative" in 10min sections-> | ||||||||
| 10A&20B | Time | 10:10 | 10:20 | 10:30 | 10:40 | 10:50 | ||
| Cumulative value | 1 | 1 | 2 | 1 | 0 |
Here is how the data looks like:
| Time | Device | Value |
| 28.3.2018 10:11 | 10A | 1 |
| 28.3.2018 10:14 | 10A | 0 |
| 28.3.2018 10:18 | 10A | 1 |
| 28.3.2018 10:48 | 10A | 0 |
| 28.3.2018 10:18 | 20B | 0 |
| 28.3.2018 10:34 | 20B | 1 |
| 28.3.2018 10:51 | 20B | 0 |
How do I write a Measure to convert the data into a table visual like this?
| Time | Cumulative value |
| 28.3.18 10:10 | 1 |
| 28.3.18 10:20 | 1 |
| 28.3.18 10:30 | 2 |
| 28.3.18 10:40 | 1 |
| 28.3.18 10:50 | 0 |
Thanks!

Hi Ikeumlaut,
One concern:
How to group those time values based on 10 min interval?
Why is 10:11 for 10A matched with 10:18 for 20B? Why should these two values belong to 10:10? While 10:14 for 10A and 10:18 for 10A belong to 10:20 and 10:30 section.
Best regards,

Hey v-yulgu-msft
sorry, that is a mistake on the chart. I edited my post and it messed up it. So the grouping is:
- 10:00
- 10:11, 10:14, 10:18
Best,
Ike
Hi Ikeumlaut,
I am still confused about this calculation. That case, the Cumulative value for "28.3.18 10:10" in result table should be 2 rather than 1. Also, the Cumulative value for "28.3.18 10:20" in result table should be 0.

- 10:00
