charts

问题 I am using d3.time.scale() (reference here) to create time scale and providing tick values using axis.tickValues([values]) (here). The ticks are rendered for the specified Date objects provided in [values]. All fine, but the tick values representations are always in current time zone of the browser. Now comes the requirement to show it in a specific time zone (say, 'Asia/Calcutta'). Is there a way to achieve this? The max option I see is for formatting the ticks, but not replacing them with

问题 I have an existing project that I want to implement zingcharts on. I have tried 3 different tutorials mainly from " https://blog.zingchart.com/2016/07/19/zingchart-and-angular-2-charts-back-at-it-again/ "blog. However I can not get that working in my project. So I decided I will try and implement it the most basic way first and later on try better ways. This is what I did but it does not shop up yet. Being new to angular2 I am not quite sure if this will work. I went to the ZingChart website

问题 I have this problem with animating of 2-datasets Stepped graph in Google Charts. It all worked well when it was just a LineChart, but my client would love to have SteppedArea chart.

Can you please take a look at this code pen? Thank you very much function drawStepChart() { var data1 = new google.visualization.DataTable();

问题 I would like to use a plain black background to my pie chart which I generate using Core Plot. I have the chart rendering nicely but the title is in a default blackColor which is hard to see on a black background. I know it's displaying because when I change the theme I can see it in black. Can anyone tell me how to change the text colour as I did with the data labels? Here is a snippet of my code... graph = [[CPTXYGraph alloc] initWithFrame:self.view.bounds]; CPTGraphHostingView *hostingView

问题 I'm adding annotations to a c# line chart. I'd like to change the text orientation but can't see any setting to allow this. RectangleAnnotationannotation = new RectangleAnnotation(); annotation.AnchorDataPoint = chart1.Series[0].Points[x]; annotation.Text = "look an annotation"; annotation.ForeColor = Color.Black; annotation.Font = new Font("Arial", 12); ; annotation.LineWidth = 2; chart1.Annotations.Add(annotation); The annotation is added to the graph correctly and the rectangle and text

问题 I visited ZingChart's documentation and came to know the methods of rendering multiple charts by calling multiple render functions like this. zingchart.render({ id:'chartDiv1', data:myChart1, height:300, width:500 }); zingchart.render({ id:'chartDiv2', data:myChart2, height:300, width:500 }); zingchart.render({ id:'chartDiv3', data:myChart3, height:300, width:500 }); zingchart.render({ id:'dashboardDiv', data:myDashboard, height:500, width:700 }); But in my code I want to write less code

问题 I'm writing a piece of software for visualization of measurement data. For this I use System.Windows.Forms.DataVisualization.Charting.Chart and I do know that I can get the shown image by chartObj.SaveImage to store it to a file. My software shall have a PDF export in which the picture should be included. For this, I'm using iTextSharp. Again, I do know how to put a picture which I have stored in a file into the PDF by iTextSharp.text.Image.GetInstance. So by now I am able to take the picture

问题 I'm working with the ASP.NET Charting Library and I've got it generating a pie chart but I'm having a problem configuring it to generate the pie chart with semi-transparent slices. If you look at the image you'll see what I'm talking about. Of the 4 pie charts the top 2 and the bottom left chart have the pie slice transparency I'm talking about.
