Hello all, I'm fairly new to MVVM. I can run the demonstration project, and I'm trying to create my own simple chart. I cannot figure out why my chart isn't doing anything - when I run my application nothing is displayed, I cannot see the chart, despite in the designer the selectable bounding box appearing in the center of the page. Below is my code:
MainPage.xaml:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:SyncTest"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:Charts="using:Syncfusion.UI.Xaml.Charts"
x:Class="SyncTest.MainPage"
mc:Ignorable="d">
<Grid Background="Wheat">
<Page DataContext="UsersViewModel" />
<Charts:SfChart HorizontalAlignment="Left" Height="449" Margin="194,139,0,0" VerticalAlignment="Top" Width="949" x:Name="test">
<Charts:LineSeries
ItemsSource="{Binding UsersList}"
XBindingPath="TimeStamp"
YBindingPath="NoOfUsers">
</Charts:LineSeries>
</Charts:SfChart>
</Grid>
</Page>

public sealed partial class MainPage : Page
{
UsersViewModel uvm;
public MainPage()
{
this.InitializeComponent();
uvm = new UsersViewModel();
test.Series[0].ItemsSource = uvm.UsersList;
}
}
public class UserProfile
{
public DateTime TimeStamp { get; set; }
public double NoOfUsers { get; set; }
}
public class UsersViewModel
{
public UsersViewModel()
{
this.UsersList = new ObservableCollection<UserProfile>();
DateTime date = DateTime.Today;
UsersList.Add(new UserProfile
{
TimeStamp = date.AddHours(0.5),
NoOfUsers = 1000
});
UsersList.Add(new UserProfile
{
TimeStamp = date.AddHours(1),
NoOfUsers = 5000
});
UsersList.Add(new UserProfile
{
TimeStamp = date.AddHours(1.5),
NoOfUsers = 3000
});
UsersList.Add(new UserProfile
{
TimeStamp = date.AddHours(2),
NoOfUsers = 4000
});
UsersList.Add(new UserProfile
{
TimeStamp = date.AddHours(2.5),
NoOfUsers = 2000
});
UsersList.Add(new UserProfile
{
TimeStamp = date.AddHours(3),
NoOfUsers = 1000
});
}
public ObservableCollection<UserProfile> UsersList
{
get;
set;
}
}
}
I have also tried again, this time following http://help.syncfusion.com/UG/winrt/default.htm#!Documents/lineseries.htm, but no luck
Am I missing some kind of initialiser out?
Thanks
