title: how to get get price value from lightweight-charts?
body: <p>I want to get the value of the point where I click on the chart.</p>
  <pre>
  
      function handleClick(param) {
         document.getElementById('y_value').value = param.point.y;
      }
  
  </pre>
  <p>But this returns the on-screen y-axis coordinates, not the price values.</p>
  <p>and this.</p>
  <pre>
  
      function handleClick(param) {
        document.getElementById('y_value').value = param.point.param.seriesPrices.get(Series).high;
      }
  
  </pre>
  <p>It returns the price value, but only the value above the chart line, not the value of the point I clicked on. How do I get the price-y value even if I click on the blank space on the chart?</p>
