C＃Xamarin绑定列表到图表

Question

I created a List and selected 1 Name from the List with all the Prices and Timestamps.

This is my List Class:

public class price
{
    public string NAME { get; set; }
    public string PRICE { get; set; }
    public string TIMESTAMP { get; set; }
}

And this is the part where I select a few things:

var singleNameWithOldestPrice =
    from p in PriceList
    where p.NAME.Contains(SelectedProduct, StringComparison.OrdinalIgnoreCase)
    group p by p.NAME into grp
    select grp.OrderBy(a => a.TIMESTAMP).ToArray();

Now I want to bind the PRICES to the Chart. I use the NuGet Package: MicroCharts. This is how you create a chart with that program:

PriceChart.Chart = new PointChart { Entries = Source };

How can I use the Prices as Source?

FULL EDITED CODE:

var singleNameWithOldestPrice =
    from p in PriceList
    where p.NAME.Contains(SelectedProduct, StringComparison.OrdinalIgnoreCase)
    group p by p.NAME into grp
    select grp.OrderBy(a => a.TIMESTAMP).ToArray();

var source = new List<Entry>();

foreach (var p in singleNameWithOldestPrice)
{
    source.Add(new Entry(p.PRICE)
    {
        Label = p.NAME,
        ValueLabel = p.PRICE,
        Color = Color.Red
    });
}

Answer 1

you need to create an array of entries , based on your example if i well understand , it should be smth like this

var source = new List<Entry>();
foreach(var p in singleNameWithOldestPrice )
{
source.Add(new Entry(p)
{
    Label = "name of every label",
    ValueLabel = p,
    Color = Color.Red
})
}
