问题 I have a problem with PyQt/its Webview. The code that is bothering me should render a chart, but it doesn't. I am using the Highcharts framework and provide the data for the javascript function that renders the chart via Python. I also check whether the webview is ready because that was a previous error of mine. The code in question looks something like this: command = ('loadPinch(' + str(random.sample(range(10000), 1000)) + ', ' + str(['2009', '01', '01']) + ');') self.webview.page()

问题 I was wondering if it was possible to return multiple charts to a single page/view using c#? Background Information C#, ASP.NET MVC3 DotNet.Highcharts Library Goal: My overall goal is to have a webpage with two charts using ASP.NET MVC3 Example HighCharts g1 = new HighCharts("chart"); HighCharts g2 = new HighCharts("chart"); return View(model, g1, g2); This is an example of what I want, but I am not too sure if this is possible. If so how would I accomplish this? If possible how would I

问题 I found this jsfiddle and I'd like to implement that after the series had been created. often I let the user update the chart, I do this by sending array of float to the setData function of the series. for example: //Build the area values for (var i = 0; i < area.length; i++) { areaValues.push(parseFloat(area[i])); } chart.series[2].setData(areaValues,false); chart.redraw(); Is there any way to add flags before the redraw without recreating the chart? 回答1: The problem is in your data format -

问题 I have text on a chart like below. I want to change the font size of the text "abc". I tried putting 'font-size':'8px' inside of the css, but it did not work. Does anyone have an idea about this? Here is the fiddle link: http://jsfiddle.net/3hGz2/ 'events': { 'load': function () { var label = this['renderer']['label']('* y='+ slope +'x'+'+('+ intercept + ')<br> R^2='+ rSquare) .css({ 'width': '150px', 'color' : 'grey', 'font-size':'8px' }) .attr({ 'stroke': 'grey', 'stroke-width': 0, 'r': 5,

问题 When calling axis.setExtremes() or axis.zoom(), the associated zoom button does not become highlighted. For example, if I programatically 'zoom' to 1-hour, I would like the '1 hour' zoom button to appear as 'pressed'. Is there a simple way to accomplish this? For more context: I want to make my app stately, so that if you view a graph, zoom, then navigate away from the graph and back to it again, I want to restore your 'zoom level'. I have this basically working by listening for

问题 I'm currently looking to implement Highcharts JS into my application, using months as the x-axis categories. However, I have gaps in my data, and wish for the chart to automatically connect the gaps. For example, if I don't have any data for March, I want February and April to connect with a linear line. Using the highcharts demo, I have edited the data to demonstrate what currently happens by default: http://jsfiddle.net/kf26t/1/ data: [7.0, 10.0, null, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18

问题 I need help with a problem with category labels for xAxis. When there is no room for all the category labels, they get crammed together and overlap each other. I have searched to see if I could find some way to ensure that this does not happen, first I looked for a scrolling solution, then some sort of zooming, and eventually I tried to go for staggerLines. The problem is, if I am to use staggerLines, I need to set the value depending on the number of categories I have. If I have 10 or less,

问题 I give that values to Highcharts pie chart: series:[ { type:'pie', name:'Ratio', data:[ ['A', 42.6], { name:'B', y:14.2, sliced:true, selected:true } ] } ] However it shows it like that at pie chart: A -> 75.00000000000001 % B-> 25 % You can format tooltips at Highcharts how about chart values? 回答1: We do have tooltip formatter options to display the value as number instead of percentage http://api.highcharts.com/highstock#tooltip.formatter tooltip: { formatter: function() { return '<b>'+
