  Goodmorning,

  I’m trying to use the zoom into the C1Chart component.

  I copy and paste the online example but not working correctly.

  I attached my usercontrol code, but I think you could not debug it because I can’t give you the customer DB ( data is confidential)

  If I debug the code

  function: _fChart_MouseUp

  lines:

  var start = _fChart.PointToData(_startPoint);

  var last = _fChart.PointToData(_lastPoint);

  I see both Y value are equal to NaN so the zoom is applied only for X axe and not for Y (PNG files)

  Could you help me to solve the strange beahviour, please?

  I have a second question for you.

  Is it possible after the zoom to know the min/max value of both the Axes?

  What my customer want to know are:

  • the new range value on Y (min = 38,00 and max = 80,00)

  • the new range value on X (min = 11:40:58 and max = 11:42:53)

  The reson is because he wants a label with data range selected by user even if can see on the chart

  Thanks Alex

  Hi Kartik,
  
  I have only one question: how can I see Case ID: CAS-35916-H7Q6M3 ?
