Realtime animated graph from data source?

Is it possible to do a realtime animated graph from an api data source? So like for example when a piece of data changes this graph visually gets updated in real time?
If so, how do you do this?
I read something about something called xaml and wpf but I couldn't find any actual examples of how to create one that works in vmix. I found an example xaml project somewhere on these forums but that one didn't have any logic just the visual xaml so that wasn't what I was looking for. I tried creating my own c# xaml project, since the example one was in visual basic which I don't know, but I couldn't get it to build into a dll or anything.
Is there an easier way to do this, or is this xaml route really the only solution, or will this xaml route not even be a solution? If so, is there a tutorial or guide that tells you from start to finish how to set up a xaml wpf project for vmix in visual studio and then build it into a dll that can be imported into vmix that supports data inputs that can be connected to data sources in vmix?
*edit I've gotten a dll to generate and import but I'm still not sure how to link things to Properties or to a data source input. I'm not sure if the code itself is even executing either.

Are you sure you want to venture there ? and with graphs no less! While you could use data to al sorts of things in a XAML (.dll) file it's processing will have to be incorporated within it's code behind (not from a loaded datasource within vmix / not directly anyways) Advice you to search the forum (or even better Google will will give you forum links) a bit more for like "vmix wpf dll" and alike XAML is a solution if you want the "title/graphics" loaded directly within vMix , other options are external application that lets you import a video feed from them like NDI or just plain screengrabs form a working application https://forums.vmix.com/...ted--data-driven--titlesPS . fun part about these .dll titles , if you want to edit them you will have to close vMx as just deleting their input is not going to release them for editing/saving

I would use a web browser input and webpage developed for that API. Chart.js is a great library for animated graphics on the web. If you need it, contact me: mart.leib.estonia@gmail.com

I was trying to do the xaml stuff with visual studio but it seems blend may be a better application for this? Can you tell me if this should indeed be possible via xaml? - Create a graphic that is essentially a bar graph.
- A Vmix Data Source input is used as input into this xaml imported component setting "properties" of some kind that then update the bars in real time ( based on vmix's data source refresh interval )?
- Potentially other configurable properties on this xaml configurable by UI for example "color of bars" or something like that. Maybe related to something called a "ShowProperties" function?
What did you mean by "not from a loaded datasource within vmix / not directly anyways", is there an indirect way to do it?

Blend is part of visual studio You can read and process what is put in a textblock fed by a vMix datasource the usual way with codebehind hence indirectly (else full data files are handled within the code ie loading and reading etc) But why not a little search in the forum first , not always need to code ? https://forums.vmix.com/...--Titolo-Grafico-a-Barre
