问题 I am having a little trouble to draw a horizontal line by using rcharts (highcharts) on a plot. I would like to use the plotLines from highcharts library to do this. Below is my code: a$yAxis(title='my_Yaxis name', plotLines=list(color='red', value=10, width=2)) Without the plotLines, my chart display with no problem. Once i added in the plotLines, it is not working. I am not sure if rcharts support plotLines in highcharts? Appreciate if any experts here can give advice. Thanks! 回答1: Hello

问题 I am implementing an animated pie chart in Highcharts where the slices pull out on mouseover and all is good apart from a issue where the on mouseOut I want the slice to return to the 'closed' position.

问题 The page accepts input from user where they paste '|' delimitated data. This data is parsed into a newSeries object. After all the parsing is done the timing to render the graph is almost 15 seconds. However if I copy the exact same newSeries object (using chrome dev tools) and manually define the object the rendering only takes 200ms. Also the interaction of the chart is almost useless after the parsed newSeries object while the manually defined object interacts perfectly. I really don't

问题 I have the a stacked column chart with a logarithmic scaled y axis (JSFiddle here, adapted from a basic demo chart) $(function () { $('#container').highcharts({ chart: { type: 'column' }, yAxis: { type:'logarithmic', min: 0.3, // I WANT THE Y-AXIS TO START AT 0.3 min: 25, // I WANT THE Y-AXIS TO END AT 25 endOfTick:false, maxPadding:0, tickInterval:0.1, }, plotOptions: { column: { stacking: 'normal', } }, series: [{ data: [5, 3, 4, 7, 2] }, { data: [2, 2, 3, 2, 1] }, { data: [3, 4, 4, 2, 5] }

问题 I have a view that renders some data in a CListView and a Highcharts graphic. Please note that the pager of the CListView works the following way: it requests the "new page" to the server, the servers renders the entire content of the page and sends it to the CListView . The body is then replaced with the content that is being sent, with something like this: $('body').html(rendered_html_response) . I also have a dropDownList that imitates this behavior. This is the code: <?php echo CHtml:
