Highcharts in JQuery Tabs - Resizing hidden tab code stops resizing visible tab

I solved one problem and created another.

I have 2 Highchart graphs in a jQuery UI tab. Initially the chart in the HIDDEN tab wouldn't resize its width when the browser window is resized. I fixed that with this code:

$( "#jQTab" ).on( 
            "tabsactivate", 
            function( event, ui ) {
               if(ui.newPanel[0].id == "jQTab_1")   { var chart = $('#container_1').highcharts();                      
                                                      chart.update({  chart: { renderTo: 'jQTab_1', width: $('#jQTab_1').width() } });
               }    
               if(ui.newPanel[0].id == "jQTab_2")   { var chart = $('#container_2').highcharts();                      
                                                      chart.update({  chart: { renderTo: 'jQTab_2', width: $('#jQTab_2').width() } });
               }    
             }
);

But this created a second problem. Now the VISIBLE chart does not change its width when the browser window's width is changed.

Here's the complete code:

                                                      chart.update({  chart: { renderTo: 'jQTab_2', width: $('#jQTab_2').width() } });
               }    
             }

Solution

  • You can use chart.reflow() instead of setting width explicitly.

    $("#jQTab").on(
  "tabsactivate",
  function(event, ui) {
    if (ui.newPanel[0].id == "jQTab_1") {
      var chart = $('#container_1').highcharts();
      chart.reflow();
    }
    if (ui.newPanel[0].id == "jQTab_2") {
      var chart = $('#container_2').highcharts();
      chart.reflow();
    }
  }
);
