All I need to achieve this is doing HighchartsExporting(Highcharts); HighchartsExportData(Highcharts); somewhere in the code, and the export options will show up by the chart.

问题 Is there any way to update the color of a single point in a grouped data set? I can't seem to find a way to reliably set the colors.

问题 I have a candlestick and volume chart similar to here, but with custom colors for the volume bars and candlesticks. This works fine until the graph is redrawn or grouped due to new data being added or a range selector button press. When the graph is redrawn or grouped, neither the candle color nor the volume bar color seems to be transferring properly. I'm using the following redraw function, but it does not seem to be having any effect. Strangely, each time the data is grouped in a new data

问题 I'm building an interactive map web-app using Highmaps and Highcharts. There's a work in progress version of it here: http://s3.eu-west-2.amazonaws.com/ds-active-travel/index.html It works fine on Desktop browsers (IE, Firefox, Chrome, Safari) however the click events don't seem to be firing when I click the map on an IOS mobile device regardless of the browser (Safari, Firefox, Chrome).
