Incubator-echarts: Sankey diagram order can't be specified

[jarben]

Version: 3.4.0

I'm struggling to find out how to manage order of nodes in the sankey diagram. For example, this diagram:

is defined (source attached sankey-order.zip) in this order:

nodes:

1. Financial Services
2. Energy & Utilities
3. Mobility Transportation

1. Germany
2. Italy
3. Netherlands

links:

1. Financial Services -> Germany
2. Financial Services -> Italy
3. Financial Services - Netherlands
   ...

where the order on the diagram is:

1. Mobility Transportation
2. Financial Services
3. Energy & Utilities

1. Germany
2. Netherlands
3. Italy

Which doesn't reflect the source code. Is there any way to do this - provide some sort of order index or simply order by given order?

Thanks for any suggestion!

It seems like the order is based on values, I've changed all values to "1" and now it shows as:

Is there any way to change ordering, say by order in the source file or provided sortFn?

Any update on this?

+1 - Another option could be allowing layoutIterations to be set to 0. Allowing the user to sort the nodes

+1 Would love more control on how to change the ordering of the nodes.

Hi everyone，I will follow this issue, sorry for letting you wait so long!

[deqingli]

Hi everyone, I have fixed this problem, which will be released next version. Now nodes sort by the order in series.data and will not be changed even your resize the diagram. Thanks for your suggestions!

[deqingli]

If there any problem after you try the new version, please reopen this issue.

这个问题，在修改了links里面的value值的时候排序又会发生改变了

Hey @deqingli ,

"Now nodes sort by the order in series.data and will not be changed even your resize the diagram"

I think this is not true. I have reordered my data array to fit the order I want and it still does not work.

@iandvt What is this solution with layoutIterations? Anyway to disable this?

[pvictor]

@jbadilla you can use layoutIterations: 0 to disable it, and apparently order is preserved.

Hi @jbadilla, If you want the node ordered by the series.data, you can set layoutIterations: 0.
