I'm trying to have data that are relative to each one of my data. I've tried to use signal's data but i didn't managed to make them relative to one and only one value of my data.
i decided to add a field in my data values. now i'm trying to change the value of this field but i can't find a way to do so.
I've tried :
"update": "datum.color === 'red' ? datum.color ='white' : datum.color ='red'"
But this does not work and result in a parsing error.
if anyone has an idea, some help would be appreciate. Thanks by advance.
@Dzious Thanks for the question!
I'm not familiar with Vega but I think going through the Vega docs for
expressions might help you out here.
I've used the examples from those docs in the past and they work great!
Thanks for your help.
Unfortunately, due to technical limitations i've had to gave up the visualisation i was trying to build.
Since this vega was designed for a real time data visualisation, this means it would be needed to refresh it every X seconds making it impossible to save the state of each component between two refreshes
Still that's good to know and i'll have a look at it later on
Once again thanks and have a great day
