            I can't seem to get plotly to display multiple graphs
            Asked 2021-Jun-07 at 04:03

            I want to create a nice graph in python, so I used plotly to create a graph, but I get an error.

            Maybe because I'm new to plotly, I don't understand the error in this code.
            The only thing I can tell is that my code is wrong.

            You can use annotations to add text, using x-values of 0, 1, 2 with the xref set to "x", and using y-values of 1.05 with the yref set to "paper" as in paper coordinates. This will ensure the annotations are above the plot.

            Firstly I don't think there is a way with the current exposed API to achieve your goal smoothly you can check the source code here.

            Try to change your find_node_coordinates function as follows (note that you should pass the counts DataFrame to):

            It looks like the Sankey library probably has a bug with node positioning computation.

            The problem can be solved by reducing node padding: nodePadding = 5.

            See it's working in the snippet:

            The customdata property is valid for a Plotly Sankey Chart graph_object as of the most recent version of Plotly (v4.14.3 at the time of posting this answer), and a description for this property can be found in the latest documentation. Updating plotly to the latest version should resolve the issue.

            Reactive Sankey Diagram in R Shiny with multiple dataframes as input
            Asked 2021-May-07 at 08:43

            It's my first time creating a dashboard and I'm running into a problem I can't seem to solve. I have created a sankey diagram and I want to be able to interactively change its contents through different dataframes (in this example: level_1, level_2, level_3). I've only ever practiced this with a regular plot, where the input would come from a variable within one dataframe which is my starting point in this piece of code (e.g. I have a df$country, so I use input$country in my plot --> Then I could choose from different countries in the dashboard sidebar, in order to change the contents of the plot). I have no idea how to do this when the input has to come from seperate dataframes.

            If you want to access any input values in the server you need to use a reactive context. shiny won't allow you to do otherwise, but even if it did, if an input value is updated, the server-side code won't update to reflect the change. Since you want both links and nodes to be dynamic and both depend on each other, a neat solution might be to store both objects in a list as follows:

            Since you are using the Sankey dialog on the official site, I will edit it to show the data structure between the ABs. Simply put, the source is A, the target is B, and the rest is an iteration of that. The additional labels as shown in the link in your question are not available in plotly's sankey dialog as far as I know. You'll have to get creative with the labels. I will add a text based explanation of what I am doing.
