.net - Canvas lines getting clipped in windows phone app -


i'm having problem content getting clipped on canvas of windows phone app. here's xaml page reproduces problem:

<phone:phoneapplicationpage      x:class="phoneapp1.mainpage"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:phone="clr-namespace:microsoft.phone.controls;assembly=microsoft.phone"     xmlns:shell="clr-namespace:microsoft.phone.shell;assembly=microsoft.phone"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     mc:ignorable="d" d:designwidth="480" d:designheight="768"     fontfamily="{staticresource phonefontfamilynormal}"     fontsize="{staticresource phonefontsizenormal}"     foreground="{staticresource phoneforegroundbrush}"     supportedorientations="portrait" orientation="portrait"     shell:systemtray.isvisible="true">      <grid x:name="layoutroot" >         <scrollviewer  x:name="chartscroller" horizontalscrollbarvisibility="visible"   >             <canvas x:name="chartcanvas" width="4000" height="1000"   >                 <line stroke="red" x1="0" x2="3000" y1="100" y2="100" />                 <line stroke="yellow" x1="0" x2="3500" y1="200" y2="200" />                 <line stroke="blue" x1="0" x2="4000" y1="300" y2="300" />                 <line stroke="green" x1="2800" x2="2800" y1="0" y2="1000" />             </canvas>         </scrollviewer>     </grid>  </phone:phoneapplicationpage>

and here's screen shot of result:

enter image description here

the problem red, yellow , blue lines seem getting clipped - expect them go further green line horizontally , lengths should different well. can't work out why happening?
