Hi

thanks for your wonderful jqchart library, its very good. Apologies if this has been asked before.

I have a requirement where separate charts all have the same x axis values. What I want to do is to have a single zoom bar on one chart which also zooms all the other charts at the same time.


I have got code like this working (it changes the y axis max). but I can't figure out how to programatically set the x-axis range on the second chart, Any help would be appreciated please

Code:

     $('#jqChart2').bind('axisZoom', function(e, data) {
       
                 
                  var chart = data.chart;
                  var axis = data.axis;
                 
                  $('.slider-time').html(Math.round(axis.actualVisibleMinimum));
                  $('#jqChart').jqChart('option', 'background', 'yellow');
                 
             

                  $('#jqChart').jqChart('option', 'axes', [ {
                     maximum : 100000
                  } ]);
                 
       
                 
               });

Hi,

Here is the code you can use:
Code:
$('#jqChart').bind('axisZoom', function (e, data) {

            var axis = data.axis;
            var minX = axis._getActualVisibleMinimum();
            var maxX = axis._getActualVisibleMaximum();

            var axes = $('#jqChartVolume').jqChart('option', 'axes');
            var bottomAxis = axes[0];
            bottomAxis.visibleMinimum = minX);
            bottomAxis.visibleMaximum = maxX;

            $('#jqChartVolume').jqChart('update');
        });


With this code you can synchronize this example:

In your case just make sure you are defining the bottom axis as first in the axis array:

Code:
axes: [
    {
       location: 'bottom',
           ...
    },
