title: Custom element in VictoryLine chart
body: <p>I am using <a href="https://github.com/FormidableLabs/victory-native" rel="nofollow noreferrer">Victory-Native</a> to display the chart in the app. In my chart I have 2 lines. One is an infinite horizontal line and the other with an arrow.</p>
  
  <p>And to my question, is it possible to render a line with an arrow in VictoryLine component? Also, in addition, I would want to have a box(gray) below of the infinite line.</p>
  
  <p><strong>The expected image is this one.</strong></p>
