TemplateValuePresenter
I want to show my x axis at a different scale than what is actually used to plot my data (conversion MHz at the time). It seems that TemplateValuePresenter is what I need but I can't find any documentation on this topic. I can get this to work using 2 axes and hiding one of them, but I feel like this is a bit of a hack solution. Is there documentation on TemplateValuePresenter? Specifically, I want to know how to access the x axis value in the DataTemplate.
Thank you!

TemplateValuePresenter
derivative of ValuePresenter
, so that you can use it anywhere a ValuePresenter
is necessary, such as the LabelPresenter
property on the MajorDivisions
of an axis:
The division value is passed as data context, so you can use {Binding}
to access (this is also how the ContentTemplate
on content controls in WPF). To convert between time and MHz, you can pass a custom binding converter.
Alternately, you could derive from ValuePresenter
or one of its children yourself and put the logic of the conversion:
public class CustomValueFormatter : ValueFormatter {
protected override string FormatCore
double valueInMHz = (double)(object)value;
double result = ConvertToTime( valueInMHz );
return result.ToString( "0.##" );
}
...
}

WPF chart: difficulty width of vertical axis
How do I do that? Currently, it is automatically resized to fit label max tick.
I just use
TemplateValuePresenter
as a simple XAML example only. When you set your own trainer of value, you can return any user interface element to display. For example, if you were derived fromGeneralValueFormatter
, you can use code like below wrap his design in aViewbox
:protected override UIElement VisualizeCore
( TData value, ValuePresenterArgs args, UIElement existingVisual ) {
var viewbox =
existingVisual as Viewbox
?? new Viewbox { MaxWidth = 16, StretchDirection = StretchDirection.DownOnly };
viewbox.Child = base.VisualizeCore
( value, args, viewbox.Child );
return viewbox;
}
Your XAML code snippet, it seems you want to specify a .NET
"0.00"
format. In this case, you can use theStringFormat
property provided byBinding
