Use data field in chart subtitle

I have charts with some data imported from a CSV. Among this data, there is a "year" field. For each chart to be displayed, I would like to have a subtitle which changes dynamically according to the year the chart is displaying.

For instance, if I'm displaying data from 2017 ("year" field in my data object), I would like to have a title "Rain data" and a subtitle "Year 2017", and the same if I switch to every year in my data object. Roughly, it should be something like:

.title({
value: "Distribució de la població per edat i sexe",
sub: function(){
return "Year " + data.year;
}
})


I've tried to do something similar to what's done in the formatting function with the params and keys, but it just doesn't recognize the fields:

.format({
"text": function(text, params) {

if (text === "usd") {
return "Trade Value";
}
else {
return d3plus.string.title(text, params);
}

},
"number": function(number, params) {

var formatted = d3plus.number.format(number, params);

if (params.key === "usd") {
return "$" + formatted + " USD";
}
else {
return formatted;
}

}
})


However, I've never been able to make this syntax work outside of formatting functions.

TLDR: How can I access fields in my data in D3plus once the data object is loaded?
