Feature Request: Select which column to display in a label

[jammiemil]

Sometimes datasets come back with more than just the Time and value columns, we have additional information in other columns that we might want to be able to put on our diagram via a label.

Currently you can only use the 'value' field but it would be really useful to be able to choose which column in the dataset to use. For example:

Rather than printing the value 1/0 on a component we might prefer to show the 'friendly_text' Success/Failure. Strictly speaking for this use case we could use valueMappings but the real use case i have in mind is much more complex than this.

'dataRef' lets us pick which time series to use and 'datapoint' lets us pick which row to use so were just missing a 'dataColumn'

That sounds interesting but I don't have any data sources available to me that can produce this data. Can you attach the expanded extract of the 'Debugging Data' log of a datasource that has this? Then I've got something explicit to code against. It's really tricky getting it right without that.

The above was made using the builtin testdata datasource in 'csv content' mode

Data looked something like:

time,value,friendly_text 1715277266000,1,Success 1715277267000,0,Failure 1715277268000,1,Success

Heres the output of the debug (couldnt get a clean copy/paste of the text itself):

thanks, so given above it looks like the data's there post enrichment, so am assuming its baulking on the type. prob just forces it to null when not a number. Will have a look.
