Allow to access to added series

[stsdc]

I'm adding a few series and have to create another ArrayList to manipulate them. Would be nice to have an access to chart.series.

        private Gee.ArrayList<Serie> series = new Gee.ArrayList<Serie>();

Use case:

    public void update (int serie_number, double value) {
        chart.add_value (chart.series[serie_number], value);
    }

I could give access to series private chart array list, but it may lead to inconsistencies / bugs if you manually add or remove series.

To match your use case, I could add an chart.add_value method which take the serie_number instead of the Series :

public void add_value_by_index(int serie_index, double value) {
    add_value(series[serie_index], value);
}

Another option would be to have access to some kind of read-only array list ;

    public void update (int serie_number, double value) {
        Gee.List<Serie> series = chart.get_ro_series();
        chart.add_value (series.get(serie_number, value);
    }

IMHO, the both options match your use case. The first is straight forward, the second is more versatile (hence, it could resolves more use cases) but requires a bit more code on your side.

What do you think ?

I created serie_list = new Gee.ArrayList<LiveChart.Serie> (); and it works, but, well, now I have two lists with same content 😅
chart.add_value_by_index would be cool

Please let me know when it works on your side.

Thanks !
