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:

SourceDestinationValue
AB100
AC50
BD90
BE10
CD25
CE15
CF10

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?

    Hi @daniel_13
    ,

    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,
    Sarina

    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,
    Sarina

    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,
    Sarina
