Develop an Addin for visio online?

[Toxicboumboum]

Hi Everyone
I made some trials and currently, I wouldn't be able to develop it in javascript. Many functions are missing, you don't know where I could find a list of all existing functions for visio Online?  Maybe with that, I would be able to do something

Thanks for your feedback

Okay so I tried to do my first javascript application but I'd like to know if there is a way to read the value in my data and to make some calulcation
So for example, I have a shape in which some shapes are getting in, so what I'd like to do is to read the value of my 1D shape and multiply it by a data that I give to my shape for example cost
Any idea of how could I do that?
I don't find a lot of doc for visio online but your table with color help me to achieve some steps

Once again, thank for your time and your help
