Sankey visualization error


#1

Hi,

I’ve followed the example for building a sankey visualization, but when I try and load the chart - I get a blank page

The query I created follows the guidelines, as far as I know, it has 5 columns (e1…e5) which can be null and a value column
I don’t know what I’m missing, are there restrictions on the strings length?

The data source is Vertica

We’re running version 1.0.0+b2720

Thanks,


#2

Are you sure the values are integers? Can you share the data you’re trying to create the Sankey from?


#3

I’m pretty sure the values are integer, the column is count(*)
Sample Data


#4

Can you share the JSON representation of the results?

Assuming your query URL is https://redash/queries/123 then it will be https://redash/api/queries/123/results.json.

Thanks.


#5

did you get this to work? I’m having the same issue


#6

Me either. I didn’t work for me while I need it.
In another topic Flow/Sequence Queries - Sankey and Sunburst Visualizations I asked for help but I give nothing. I guess my request may be lost.
