问题 I am using Live Charts WPF to draw some charts. To make each column bar of different color I added multiple series, but it doesn't show x-axis labels of all series. Why? senderChart.Series = new SeriesCollection(); int i = 0; var ax = new Axis { Separator = new LiveCharts.Wpf.Separator() { Step = 1 }, Labels = dateValues, ShowLabels = true }; senderChart.AxisX.Add(ax); foreach (var val in dataValues) { senderChart.Series.Add(new ColumnSeries { DataLabels = true, Title = dateValues[i], Values

问题 I recently encountered a tool called LiveChart and decided to test it out. Unfortunately I've been having some problems figuring out how to update the chart values in real time. I'm pretty sure there's a clean and correct way of doing it, but I can't seam to find it. I would like to be able to update the values through a private void or button. In my code I'm testing it out with a ToolStripMenu. [CODE]: using System; using System.Collections.Generic; using System.ComponentModel; using System

问题 I kept rendering a black/blank image of a UserControl not shown in window. The UserControl contains LiveChart's CartesianChart and few UIElements. First I borrowed solutions from SO: C# chart to image with LiveCharts and Github: Live-Charts/ChartToImageSample.xaml.cs and apply SaveToPng and EncodeVisual on a simple UIControl generated in runtime (not added or shown in window), which works. Canvas control = new Canvas() { Width=100, Height=100, Background = new SolidColorBrush(Colors.Pink)};

问题 I need help creating a (test) pie chart with LiveCharts. I am using this xaml code <Grid> <lvc:PieChart x:Name="myPieChart"/> </Grid> and then in code behind LiveCharts.Wpf.PieSeries ps = new LiveCharts.Wpf.PieSeries { Values = new LiveCharts.ChartValues<decimal> { 1, 3} }; myPieChart.Series.Add(ps); But instead of getting one pie chart with 2 slices, I get 2 concentric pie charts, each with 1 complete slice only. 回答1: Ok, I was able to get the job done by doing this LiveCharts

问题 I just can't find a solution for changing the format of the y-axis tick labels. Now I get labels like 0.03 and 0.035 . But I always need three digits behind the decimal point. The big question is, how to access the label format? This is my code: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows; using System.Windows.Forms; using System

问题 I'm using LiveCharts in WinForms. Reason why I'm not using WPF is because I don't want to rewrite the GUI in WPF, so I'm trying to see if I can make LiveCharts work in WinForms. I'm saving the LiveCharts control as an image to a PDF, so the title needs to be on the chart itself. I cannot find any functionality for adding a title on the chart. What I have tried is the following: VisualElement title = new VisualElement(); title.HorizontalAlignment = System.Windows.HorizontalAlignment.Center;

问题 I am using sample code from live charts Code behind private double _axisMax; private double _axisMin; public Plotter() { var mapper = Mappers.Xy<MeasureModel>() .X(model => model.DateTime.Ticks) //use DateTime.Ticks as X .Y(model => model.Value); //use the value property as Y //lets save the mapper globally. Charting.For<MeasureModel>(mapper); //the values property will store our values array ChartValues = new ChartValues<MeasureModel>(); //lets set how to display the X Labels

问题 I'm using beto-rodriguez's livecharts for WPF. I get data for charts from xml file and than i draw charts one above another, charts representing data have same number of spots on X axis and ZOOM and PAN are enabled with ch.Zoom = ZoomingOptions.X; and ch.Pan = PanningOptions.X; My question is possible to zoom or pan one (doesnt matter which) of those charts and that all of them are zoomed or panned so that i have vertically aligned X axis of all of them? Basically if I zoom or pan on one

问题 I am displaying data in my livecharts and Label values are binded (visible in debugging). But somehow in the UI, it is showing one or two values instead of all the values in string array from the backend. Model.cs Code: private string[] _Labels; public string[] Labels { get { return _Labels; } set { SetProperty(ref _Labels, value); } } ModelViewCode.cs Labels = new[] {"Maria", "Susan", "Charles", "Frida"}; XAML: <lvc:CartesianChart.AxisX> <lvc:Axis Labels="{Binding Labels}"> </lvc:Axis> </lvc
