Update Existing Line Similarity In Web Player

Tyler Kendle

Recommended Posts

Hi everyone,
I'm trying to give my end users the ability to update an analysis in the web player where I've created Line Similarity rankings based off the marking of a specific region.  In Spotfire Analyst I'm able to click on a different region then right click on the Line Graph and then Line Similarity.  This gives me the ability to Update Existing based on new marked lines.

The issue I'm having is I'm not able to do that on the Web Player.  Does anyone have any suggestions or possible work arounds that could work.  I was thinking an IronPython script to mark a row, and then maybe there is a way to update the Line Similarity with a different IronPython script but I didn't see any examples that I thought would work.

Thank you,

Hi Tyler,

I think you are right, the line similarity is not available in the web player, see also the note in this document: https://docs.tibco.com/pub/spotfire_server/latest/doc/html/TIB_sfire_server_tsas_admin_help/server/topics/spotfire_advanced_analytics_license.html. Most of the features of advanced analytics are only available in the Analyst client.

Looking at our ideas portal, there is an idea for this functionality, that is under consideration: https://ideas.spotfire.com/ideas/TS-I-8465

So far, I haven't been able to find an iron python script that could be used as workaround, although there is some code available on fitting models: 


But the API that is used, doesn't specifically mention the Line Similarity, as it does for Holt Winters Forecast for example (this is the API link: https://docs.tibco.com/pub/doc_remote/sfire_dev/area/doc/api/TIB_sfire-analyst_api/html/N_Spotfire_Dxp_Application_Visuals_FittingModels.htm).

You may have a look at the API list and see if there is anything in it that could serve for your use case.

Kind regards,

Hi David,
Thank you for taking the time to look into this for me.  I'll take a look through those articles, maybe there is something in there that I can use to update the Line Similarity.  I'll also give that idea in the portal a vote for consideration.  Thanks David!
