    <p>I am using one highchart to control another one. After setting the chart.evetns.selection, chart.yAxis.getExtremes can't return correct dataMax if I zoom a tiny region. However, if I click once again, then it return the correct one. Any suggestion to avoid this? here is my code: <a href="http://jsfiddle.net/tianhuidong/Jhupu/" rel="nofollow">http://jsfiddle.net/tianhuidong/Jhupu/</a></p> <pre><code>$(function () { $('#container1').highcharts({ chart: { events: { selection: function (event) { m1 = event.xAxis[0].min m2 = event.xAxis[0].max var chart1 = $('#container1').highcharts() var chart2 = $('#container2').highcharts() chart1.xAxis[0].setExtremes(m1, m2); chart2.xAxis[0].setExtremes(m1, m2); }, click: function (event) { var chart1 = $('#container1').highcharts() var chart2 = $('#container2').highcharts() xx = chart1.xAxis[0].getExtremes() yy = chart1.yAxis[0].getExtremes() alert(yy.min) alert(yy.dataMax) alert(yy.userMax) alert(Object.keys(yy)) chart1.xAxis[0].setExtremes(xx.dataMin, xx.dataMax); chart1.yAxis[0].setExtremes(yy.dataMin, yy.dataMax); chart2.xAxis[0].setExtremes(xx.dataMin, xx.dataMax); } }, zoomType: 'xy' }, tooltip: { crosshairs: true }, plotOptions: { series: { events: { legendItemClick: function (event) { var chart1 = $('#container1').highcharts() var chart2 = $('#container2').highcharts() //alert(Object.keys(chart1.series[0])) chart2.series[0].hide() //chart2.showResetZoom() //alert(Object.keys(chart.resetZoomButton)) } } } }, xAxis: { categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec', 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'] }, series: [{ data: [29.9, 71.5, 186.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4, 29.9, 71.5, 186.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4] }] }); }); $(function () { $('#container2').highcharts({ xAxis: { categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec', 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'] }, series: [{ data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 116.4, 194.1, 95.6, 54.4, 29.9, 71.5, 186.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4] }] }); }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
