If (handler != null) handler(this, new Propert圜hangedEventArgs(propertyName)) Propert圜hangedEventHandler handler = Propert圜hanged Protected virtual void OnPropert圜hanged(string propertyName = null) XLabelFormatter = new CustomLabelFormatter(xAxisLabels) we can also use it to transform an integer value to a string (text) value In most cases this is used to format a numeric value, e.g. The ILabelFormatter allows us to substitute a string value for a data-value. Public event Propert圜hangedEventHandler Propert圜hanged Let’s have a look at the code for ChartViewModel.cs public class ChartViewModel : INotifyPropert圜hanged We will discuss what is a LabelFormatter later, but please make a mental note, we are setting AutoTicks=false, MajorDelta = 1, MinorDelta = 0.2 and binding to ChartViewModel.XLabelFomatter. ![]() Notice that the XAxis has a binding to LabelFormatter: Oh wait, I’m wrong! There is something special here. There is a single ChartModifier – in this case a CursorModifier. The ScIChartSurface has a single binding of DataSet to ChartData on the ChartViewModel and the DataContext of the control is set to an instance of the ChartViewModel. The SciChartSurface contains a single RenderableSeries (column series), and the YAxis and XAxis are of type NumericAxis. The ChartView / ChartViewModel defines the XAML and data to render the chart. Let’s begin to break this application down. The Screenshots, XPS Printing and XAxis Labels Test App ![]() Next, running the application, you should see this output: If you don’t have the SciChart trial you will need to download this also and ensure .dll is referenced. We will talk you through the code so you can discover how we did screenshots and XPS export.įirst download the source code, you can find i.e. In this we’re going to go a little differently. ![]() In many of our tutorials, we walk you through how to create it from the ground up. We present a demonstration application which does these, plus shows a few other neat tricks to get X-Axis text labels on the chart (instead of numeric data). I can’t recall the number of questions we’ve received on whether SciChart supports render to bitmap (screenshots), printing to XPS or PDF and text labels on X-Axis, so we’ve created a tutorial which encompasses all three! Hurrah!įortunately both Render-to-Bitmap and XPS printing are both features native to WPF. Screenshots, XPS Printing, X-Axis Text Labels Posted by Andrew on 18 February 2013 09:35 PM
