FAQ: How to Show/Hide Axis Title without changing the axis text

The solution is to use the Axis TitleStyle to control visibillity of the axis title text block via an attached property.

Start out by creating this code:

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;

namespace WpfApplication2
{
    // Define attahced property
    public class AxisExtensions
    {
        public static readonly DependencyProperty DrawAxisTitleProperty = DependencyProperty.RegisterAttached(
            "DrawAxisTitle", typeof(bool), typeof(AxisExtensions), new PropertyMetadata(true));

        public static void SetDrawAxisTitle(DependencyObject element, bool value)
        {
            element.SetValue(DrawAxisTitleProperty, value);
        }

        public static bool GetDrawAxisTitle(DependencyObject element)
        {
            return (bool)element.GetValue(DrawAxisTitleProperty);
        }
    }
}

XAML

<Window x:Class="WpfApplication2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:s="http://schemas.abtsoftware.co.uk/scichart"
        xmlns:common="clr-namespace:WpfApplication2"
        Title="MainWindow" Height="350" Width="525">

    <Window.Resources>
        <BooleanToVisibilityConverter x:Key="b2v"></BooleanToVisibilityConverter>
        <Style x:Key="BottomAxisTitleStyle" TargetType="s:AxisTitle">
            <Setter Property="ContentTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="{Binding}"
                                   Visibility="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=s:DateTimeAxis}, Path=(common:AxisExtensions.DrawAxisTitle), Converter={StaticResource b2v}}"/>
                    </DataTemplate>
                </Setter.Value>
            </Setter>                                    
        </Style>
    </Window.Resources>
    <Grid>
        <s:SciChartSurface>
            <s:SciChartSurface.XAxis>
                <s:DateTimeAxis AxisTitle="Hello World!" TitleStyle="{StaticResource BottomAxisTitleStyle}" common:AxisExtensions.DrawAxisTitle="True"/>
            </s:SciChartSurface.XAxis>
            <s:SciChartSurface.YAxis>
                <s:NumericAxis/>
            </s:SciChartSurface.YAxis>
        </s:SciChartSurface>
    </Grid>
</Window>

That’s it!

The attached property AxisExtensions adds a boolean property to the Axis itself. Next, the declared Axis TitleStyle has a TextBlock with Text-value bound to its data context (in this case the axis title string), and Visibility set to a RelativeSource binding up to the AxisExtensions.DrawAxisTitle attached property.
