Empty values in Confluence chart macro

[Matt Block]

I am trying to create a burndown chart in Confluence. The main problem I have with the display is that empty values are dipslaying as 0 on the chart. I want the axis to continue as I have an expected burndown line and actual burndown line, but I don't want empty values to display for the actual burndown line. Is there a way to get empty values to not display on the chart?

NOTE: I'm only interested in learning if this is possible in Confluence using the chart macro. I'm not interested in other paid macros or discussing how to do this in another tool (JIRA, Excel, etc). I already know how to solve the problems there.

Wait, I am a genius ;-)

{chart:type=line|title=Burndown|yLabel=Points|xLabel=Sprint 
|dataDisplay=false|dataOrientation=vertical} 
||Sprint || Estimate ||
| 1       | 75        |
| 2       | 60        |
| 3       | 45        |
| 4       | 30        |
| 5       | 15        |
| 6       | 0         |

||Sprint || Actual    ||
| 1       | 75        |
| 2       | 55        |
| 3       | 42        |
| 3       | 42        |
| 3       | 42        |
| 3       | 42        | 

{chart}

Thanks, your example helped me.  I was working on a burn-up chart.  I did find that (at least in confluence cloud) you don't have to duplicate the values for sprint 3.  You can just have one table with sprints 1-6 (or days 1-10 or whatever) and then another table with only the sprints/days for which you have value and it will work.

@Daniel Hodson1 that's a brilliant idea indeed, worked for me for making a burndown chart. Thanks!

You can try Chart from Table macro (Table Filter and Charts app) - it doesn't interpret empty values as zeros.

Same issue!!! How solve problem?

Hi Matt - fighting the exact same problem. Did you find a solution?

[Bob Swift]

If I remember correctly, I don't think so. Can you post a simple example that shows the problem?

[Matt Block]

So an example would be a chart based off this table...

Day of Sprint,Points Remaining,Guideline

0,30,30

1,30,27

2,27,24

3,22,21

4,,18

5,,15

6,,12

7,,9

8,,6

9,,3

10,,0

If this were my burndown chart and it was currently day 4. I would like to see the line stop after the 3rd day. Instead it assumes 0 for blank values so the line drops to 0 on day 4.
