Make texts look the same size in xaml

I write an XAML application and I have a problem with the size of text. How can I make the texts look complete but with the same size? (make it responsive).
This is a small example of my XAML code:
<!-- (0, 0) Availability -->
<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Viewbox Stretch="Uniform">
<Grid Grid.Column="0">
<TextBlock Style="{StaticResource OeeText}">Disponibilidad</TextBlock>
</Grid>
</Viewbox>
<Grid Grid.Column="1">
<TextBlock Style="{StaticResource OeeValues}">100%</TextBlock>
</Grid>
</Grid>
In the Window App, the text shows as:
How can I make all three texts look the same size?
Thanks )

You may define the size of a textBox in a responsive manner using the ViewBox Component but you have to use it inside the grid , in order to wrap the textBox Control
<Viewbox Stretch="Uniform" MaxWidth="200" MaxHeight="200" MinWidth="100" MinHeight="100">
<TextBox x:Name="MyTextBox" />
</Viewbox>
You may also control the size by setting its max/min of width and height as mentioned in the docs

Add canvas that takes all window size, and a button in bottom left corner, margined by percentage

I am trying to have a canvas that takes all window size upon resizing, and a button over it, in the bottom left corner, but which resizes with the window(up to some max size, maybe), and the margin from the button to left and bottom resizes with the window as well.
I have tried to achieve it with a grid like this:
<Canvas Background = "LightGray" x:Name="PaintCanvas"
VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
Height="auto" Width="auto">
<Grid ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="8*" />
<RowDefinition Height="20*" />
<RowDefinition Height="62*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="8*" />
<ColumnDefinition Width="5*" />
<ColumnDefinition Width="87*" />
</Grid.ColumnDefinitions>
<Button x:Name="testBut" Content="TEST"
Grid.Column="1" Grid.Row="1"
MaxHeight="150" MaxWidth="50"
/>
</Grid>
</Canvas>
Edit: it seems that i have to fill the canvas with the grid.

So, here's how i handled it:
Added my grid(with predefined empty cells that serve as margins) as the only child of Window. Then added Canvas as child of grid, but specified it to span across all its rows and columns - filling whole grid(and Window):
<Canvas Background="WhiteSmoke" x:Name="PaintCanvas"
VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
Grid.RowSpan="3" Grid.ColumnSpan="3"/>
Finally,i put the button in needed cell

RowDefinition Height not working when using bound property on Grid in ListView?

An odd behavior is occurring when trying to set the Height of a Grid Row that is inside a ListView on Xamarin.Forms. When I hard code the value, for example:
<RowDefinition Height="40" />
... the Height of the Row gets set to 40. I know because I've tried different values and the Height changed proportionally.
However when I set the same property by binding it to a property on the View Model, no matter what the value of the property is, the Height of the Row always remains the same.
<RowDefinition Height="{Binding SmallImageHeight}" />
Here is the XAML code on my View:
<ListView ItemsSource="{Binding Items}" HasUnevenRows="True" x:Name="itemsListView">
...
<StackLayout>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="{Binding SmallImageHeight}" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*" />
<ColumnDefinition Width="5*" />
</Grid.ColumnDefinitions>
<Image Source="{Binding SmallImagePath}"
Aspect="AspectFill"
Grid.Row="0"
Grid.Column="0" />
<StackLayout Grid.Row="0" Grid.Column="1" >
...
</StackLayout>
</Grid>
</StackLayout>
...
</ListView>
I already tested the property on the view model by binding the height to an image outside the ListView and it works. Does anybody know why thins happens and how to fix it?

This is how I solved it if anyone else has the same issue. Any item inside the listview is bound to the ItemsSource objects. To solve the problem it is necessary to bind the height by referencing the Root of the ViewModel (BindingContext)
<RowDefinition Height="{Binding Source={x:Reference Name=itemsListView}, Path=BindingContext.SmallImageHeight}" />

Bind Width property of elements which are horizontally stretched

I have a group box and grid splitter control in a column of the grid. Horizontal Alignment of group box is set to stretch so it occupies all the space when I drag the splitter. All works well.
Now I need to store the value of the group box in a property of the bound object but as soon as I bind the width property it gets stuck it is no longer stretching itself upon stretching the splitter.
I know the reason because now the binded property is responsible for its width and it is not getting changed. But don't know how to make it work. This is my XAML.
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid x:Name="InnerGrid" HorizontalAlignment="Stretch" Height="{Binding ElementName=Control1,Path=ActualHeight}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" MinWidth="200"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<GroupBox Header="{Binding TrackName}" VerticalAlignment="Stretch" Margin="3 0 3 0" HorizontalAlignment="Stretch" />
<GridSplitter Width="5" VerticalAlignment="Stretch" Focusable="False" Background="Gray"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>

Perhaps you're actually interested in binding the ColumnDefinition width, as so:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{Binding Width}" MinWidth="200"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>

As I understand you need read calculated width of the GroupBox. You can use ActualWidth property for this purpose.
Edit:
You can write custom GroupBox and make use of Dependency Properties:
public class MyGroupBox : GroupBox
{
public static readonly DependencyProperty CurrentWidthProperty =
DependencyProperty.Register("CurrentWidth", typeof(double),
typeof(MyGroupBox), new FrameworkPropertyMetadata(0d));
public double CurrentWidth
{
get { return this.ActualWidth; }
set { SetValue(CurrentWidthProperty, value); }
}
}
XAML:
<Window x:Class="FunWithWpfAndXP.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:FunWithWp"
Title="Window1" Height="300" Width="300">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" MinWidth="200"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<local:MyGroupBox CurrentWidth="{Binding Path=myProp}" VerticalAlignment="Stretch" Margin="3 0 3 0" HorizontalAlignment="Stretch"/>
<GridSplitter Width="5" VerticalAlignment="Stretch" Focusable="False" Background="Gray"/>
</Grid>
</Window>

The problem is that your binding is resetting the width changed by the GridSplitter, setting the Mode of the GroupBox Width binding to OneWayToSource should (probably) help you, you'll probably get something like this:
<GroupBox Width="{Binding Path=MyGroupBoxWidth, Mode=OneWayToSource}"/>
MSDN:
OneWayToSource: Updates the source property when the target property changes.
Setting this will cause that the property in your code will be updated but not the other way around

Legend outside the plot

do you know how can I put the Legend outside the plot area?
(Both in code and in xaml)
Thank you for your help!
cis

There is no implementation in the current D3 library to move the legend outside the plotter. The most that can be done is to move the legend to a different place in the plotter by editing the Legend.xaml.cs file in the source code. You will have to change the dependency properties in the code-behind to move the legend around the area of your plotter.
If you want to put your legend outside the plotter, you will have to recreate the Legend.xaml to make it independent of the plotter, but still receive the same information it needs to create the legend. If you do manage to do that, please post it here as an answer!

Maybe the answer came a little late, but I also ran into this problem.
This is the style of Microsoft.Research.DynamicDataDisplay.Plotter.cs:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Microsoft.Research.DynamicDataDisplay"
xmlns:common="clr-namespace:Microsoft.Research.DynamicDataDisplay.Common">
<Style x:Key="defaultPlotterStyle" TargetType="{x:Type local:Plotter}">
<Setter Property="Control.Background" Value="White"/>
<Setter Property="Control.BorderBrush" Value="Black"/>
</Style>
<ControlTemplate x:Key="defaultPlotterTemplate" TargetType="{x:Type local:Plotter}">
<common:NotifyingGrid Name="PART_ContentsGrid" Background="{TemplateBinding Control.Background}">
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition/>
<RowDefinition Height="auto"/>
</Grid.RowDefinitions>
<common:NotifyingStackPanel Name="PART_HeaderPanel" Orientation="Vertical" Grid.Row="0"/>
<common:NotifyingGrid Name="PART_MainGrid" Row="1">
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition/>
<RowDefinition Height="auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<common:NotifyingGrid Name="PART_CentralGrid" Column="1" Row="1" ClipToBounds="true" Background="Transparent"/>
<common:NotifyingCanvas Name="PART_MainCanvas" Grid.Column="1" Grid.Row="1" ClipToBounds="true"/>
<Rectangle Name="PART_ContentBorderRectangle" Grid.Column="1" Grid.Row="1"
Stroke="{TemplateBinding Control.BorderBrush}"
StrokeThickness="{TemplateBinding Control.BorderThickness}"/>
<common:NotifyingStackPanel Name="PART_LeftPanel" Grid.Column="0" Grid.Row="1" Orientation="Horizontal"/>
<common:NotifyingStackPanel Name="PART_RightPanel" Grid.Column="2" Grid.Row="1" Orientation="Horizontal"/>
<common:NotifyingStackPanel Name="PART_BottomPanel" Grid.Column="1" Grid.Row="2" Orientation="Vertical"/>
<common:NotifyingStackPanel Name="PART_TopPanel" Grid.Column="1" Grid.Row="0" Orientation="Vertical"/>
</common:NotifyingGrid>
<common:NotifyingCanvas Name="PART_ParallelCanvas" Grid.Column="1" Grid.Row="1"/>
<common:NotifyingStackPanel Name="PART_FooterPanel" Orientation="Vertical" Grid.Row="2"/>
</common:NotifyingGrid>
</ControlTemplate>
</ResourceDictionary>
So, the trick is you have to modify the legend's parent and its parent properties, to move the desired elements to the right place in the right size.
PART_CentralGrid element contains the Legend item.
I did the following:
legendGrandparent.Width = plotter.Width - 100;
legendGrandparent.HorizontalAlignment = HorizontalAlignment.Left;
legendParent.ClipToBounds = false;
legend.LegendLeft = plotter.Width - 125;
where legendGrandparent is the PART_MainGrid and legendParent is the PART_CentralGrid.
