When I set up axes in code LabelFormat is ignored.

I find when I set up axes in code the LabelFormat seems to not work. I made an example similar to Chart2 in the Zooming and Panning sample where I set up 2 charts that should be identical. The axes for the first chart are set up in XAML, and the axes for the second chart are set up in code. I specified LabelFormats of "{}{0:0.00}" in both cases, but when I run the program the second chart shows no decimal places in the labels.

Here is my XAML

   <Grid>
    <Grid.RowDefinitions>
     <RowDefinition/>
     <RowDefinition/>
    </Grid.RowDefinitions>
    <ms:Chart Grid.Row="0" x:Name="lfChart1">
     <ms:LineSeries SeriesBrush="Green" />
     <ms:Chart.BackgroundElements>
      <ms:ChartGrid />
     </ms:Chart.BackgroundElements>
     <ms:Chart.XAxis>
      <ms:ChartAxis Minimum="0" Maximum="12" Title="X Axis" LabelFormat="{}{0:0.00}" TickMarkMode="Movable" />
     </ms:Chart.XAxis>
     <ms:Chart.YAxis>
      <ms:ChartAxis Minimum="0" Maximum="10" Title="Y Axis" LabelFormat="{}{0:0.00}" />
     </ms:Chart.YAxis>
    </ms:Chart>
    <ms:Chart Grid.Row="1" x:Name="lfChart2">
     <ms:LineSeries SeriesBrush="Green" />
     <ms:Chart.BackgroundElements>
      <ms:ChartGrid />
     </ms:Chart.BackgroundElements>
    </ms:Chart>
   </Grid>

Here is the relevant code

  private void FillLFChart()
  {
   IList points = new List<object>();
   for (int x = 0; x <= 12; x++)
   {
    double y = _random.NextDouble() * 10;
    points.Add(new Point(x, y));
   }
   lfChart1.Series[0].ItemsSource = points;

   lfChart2.XAxis = new ChartAxis()
   {
    Minimum = 0.0,
    Maximum = 12.0,
    Title = "X Axis",
    LabelFormat = "{}{0:0.00}",
    TickMarkMode = TickMarkMode.Movable
   };
   lfChart2.YAxis = new ChartAxis()
   {
    Minimum = 0.0,
    Maximum = 10.0,
    Title = "Y Axis",
    LabelFormat = "{}{0:0.00}"
   };

   lfChart2.Series[0].ItemsSource = points;
  }

Hello

In C# you will need to remove the first set of empty curly brackets from the string format. So this will be LabelFormat = "{0:0.00}". Remember to do this for both axes. The first set of empty curly brackets is a XAML trick, it means to treat the rest of the attribute as a string. This is important for setting string format properties because the curly bracket can mean other things in XAML.

Hi Jason,

Thanks for the information--I wasn't aware of what the {} means.
