title: Chart.js How to actualize canvas due to new x-axis range typed by user
body: <p><strong>What I have:</strong></p>
  <p>On chart.js there is a canvas which has exact values on x-axis e.g. from 1 to 9
  There will be a possibility for user to type a new range which user who is interested to see another view, let say it is limited scope. In me repo I limited this function and typed values start = 3 and end = 6 (this new limit - from 3 to 6 I want to see).</p>
  <p>I've already have a method which constraints data presented on graph, but due to the fact that upgrade button is outside the <code>canvas</code> I don't know how to force chart to be upgraded.</p>
  <p><strong>What I need:</strong>
  How to force chart to be updated?</p>
