currently I'm trying to make a chart with WPF chart toolkit,
the requirement is that Y-axis should show as the image below:
which describes
*0~84 is Level D
*85~99 is Level B
...
I'm not sure whether chart toolkit can make this type of Y-axis scale.
I'll try to put TextBox controls directly into the canvas for "Level *" label if above is not supported by the chart toolkit, still I have problem how can I show only 85, 100, 115 as scale of Y axis.
Any help would be appreciated. Thanks.
You can try to use a Converter for the axis label of your chart. Something like this: XAML
<chartingToolkit:Chart Name="chart1" >
<chartingToolkit:Chart.Resources>
<HideConverter x:Key="HideConverter1" />
</chartingToolkit:Chart.Resources>
<chartingToolkit:Chart.Axes>
<chartingToolkit:LinearAxis Orientation="Y" ShowGridLines="False" Interval="5" Minimum="0" Maximum="150" >
<chartingToolkit:LinearAxis.AxisLabelStyle>
<Style TargetType="chartingToolkit:AxisLabel">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="chartingToolkit:AxisLabel">
<TextBlock DataContext="{TemplateBinding FormattedContent}" Text="{Binding Converter={StaticResource HideConverter1}}" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</chartingToolkit:LinearAxis.AxisLabelStyle>
</chartingToolkit:LinearAxis>
</chartingToolkit:Chart.Axes>
</chartingToolkit:Chart>
and in your codebehind the converter is
public class HideConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
// value is the current tick on the Y axis
int x = int.Parse(value.ToString());
switch (x)
{
case 85:
case 100:
case 115:
return value;
case 40: // I set 40 to be in the middle between 0 and 85
return "Level D";
case 90:
return "Level C";
case 110:
return "Level B";
case 130:
return "Level A";
default:
return null;;
}
return null;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
