问题 I'm trying to generate a PDF report using the Wicked_pdf gem and Highcharts. I've already tried to set animation , enableMouseTracking and shadow false.

问题 I have some tabs which are generated dynamically. Clicking on any of this tabs loads multiple charts(three or four) like a pie, column or a linechart simultaneously.

问题 I'm trying to display dates (i.e., by day) along the xAxis using HighCharts. I'm using the Lazy High Charts gem w/ Rails to do so. For the HighCharts 'data' argument, I'm passing in a nested array with [[date, revenue], [date, revenue], [date, revenue]...etc]. The yAxis with the revenue is working correctly, but the corresponding date in the xAxis is not. Here's the controllers code : def graph_orders sales_and_date_array = [] Order.revenue_to_array(sales_and_date_array) puts sales_and_date

问题 Got a problem with highcharts. I have series with dated data (debit, month) and want to graph it. I can graph data (debit only), but when i want to add datetimes, there are 2 problems : x_axis data are bad displayed (00:00:00.00)(00:00:00.00), expecting month-year (08/2012) Tooltip told me "Invalid date" def index @ops = getConstantOps() @js_data = [] @ops.each { |f| tmp = [f.date_operation,f.debit] @js_data.push(tmp) } @h = LazyHighCharts::HighChart.new('graph') do |f| f.options[:chart][
