Sankey - input data
Hi community,
I'm trying to create a Sankey chart using the DSS plugin.
I've organised my input data so I have three columns:
| Source | Destination | Value |
| A | B | 100 |
| A | C | 50 |
| B | D | 90 |
| B | E | 10 |
| C | D | 25 |
| C | E | 15 |
| C | F | 10 |
However the chart isn't generating from this.
I've made sure there is no repetition on source/destination names and the chart generates on sankeymatic. What am I missing?

I know you opened a support ticket on this as well - just to confirm publicly, the plugin does not currently support HDFS datasets as the input dataset.
Thanks,

Hi @Jeff_Edwards
,
When you try and create the chart, are you running into the message "Nothing to display" or another type of message?I tested out the sample data you provided, and was able to create a browsable and static chart and if I create a browsable chart first, I do encounter the "Nothing to display" message with the following settings:
In order to resolve this, I clicked on Actions > Refresh view, which loads the chart for me:
My chart:
If this was your issue can you test this out and see if that loads the chart for you? If you are seeing a different message, please attach a screenshot of the message and your chart settings in case that helps with troubleshooting!
Thank you,

Hi @SarinaS
,First of all, thank you so much for running a test of the data. It's reassuring to see that building (some form of) chart is possible for you with the test data.
One thing I notice immediately though is that your chart does not include the B node - everything seems to be routed through C. Was this a copy/paste error maybe, or is there something else going on?
When I try to build the chart I don't actually get any error message. I just have a blank screen.
I also don't seem to have the actions button that you do in the screenshot you shared.
How is your test data stored - does it match the schema below?
Thanks

Hi @Jeff_Edwards
,Regarding the missing A->B section, I think that's because I was showing my browsable chart. If I look at the static chart, I do see the B node, I think as expected:
Regarding the blank screen, I think it would be most useful if we could take a look at an instance diagnostic from your instance after you reproduce the issue to determine why you are getting the blank screen. To share it with us, could you open a chat with us (you can do this from the Dataiku home page) or a support ticket? You can just reference this post and my name and we can go from there!
Thanks,
