One of the requests from the client was to see the retrieved data in a graph. Furthermore, he wanted to see a live update every second of the retrieved data in that graph. After some searching I found the OxyPlot library. Although the package is already downloaded more then 10 times there are not so many blog posts to find about implementing the library.
The easiest way to include OxyPlot in you application is by using the Nuget package manager in Visual Studio. After the project is created open up the Package Manager Console and type following commands at the prompt and hit enter after every command :. First step is to create the ViewModel for our MainWindow. Right click on the project and add a folder ViewModels. Right click the folder and add a class MainWindowModel.
I saw a post in the discussions on codeplex that they are looking to add complete MVVM model but are short of time at the moment. Maybe the next version will support it. After inheriting the interface we have to implement the PropertyChangedEventHandler event as shown below. The setter will call the OnPropertyChanged method that will notify the view there is a change on the object that may have to be rendered.
We can now add the graph to the MainWindow.
Using OxyPlot With Xamarin.Forms
Last part for our setup is to bind the view model to the view. Add a private property of our view model and initiate this property in the constructor. We have of course add some data to the PlotModel before the graph will be rendered. Back to our view model to set up our view model. First start will be adding the axes for the graph so OxyPlot knows where to plot the points. Create a new method SetUpModel in our view model class. The set up for the legend of the graph is self explanatory.
Creating graphs in WPF using OxyPlot
The ValueAxis is similar initiated, only did we position the axis on the left side and tell the Axis to start at the value 0. Now we have our graph and are ready to add some graph lines to the PlotModel. To avoid complexity I added a class Data. This will allow us to loop over the result and then add a LineSerie per Detector. We make use of the DateTimeAxis builtin funtion to convert a date to a double and add the value line For the second question of our client we had to add real-time updates.
This will allow us to fetch the data per detector. After retrieving the correct LineSerie we can add the points like we did in the LoadData method. Rendering event.The post is devoted to the Wpf application that shows emulated real-time data in charts.
It could be used as base for monitoring application, when data service provide real data like, for example, number of http requests or CPU temperature. OxyPlot library is used for chart controls, as it is lightweight and easy to use. Full code is accessible on GitHub Blog repository. Solution uses C 6. Net 4. TypeLibraryand OxyPlot chart control. Solution contains one Wpf application project. The main part of the application is chart repository — the object that receives data from services, parses and provides it to consumers.
Data service emulates data, but in real-world example it reads data from external source, and put it to repository. Data service is controlled by application, and there are several instances could be executed. User controls consume data from repository and update charts.
Properties are used by consumers, that in this application are view models for user controls. LineCountList provides one-dimensional series as values for some process. Repository keeps not great than values. Data services use AddLineCount to add new value.
ColumnCountList provides two-dimensional data like the set of pairs index, valueand could be used as distribution of process values. Data services use AddColumnCount to add pair index, new value.

Good afternoon, right now i have this chart but i want to add the red and blue lines for in the bar chart. Thanks for your help. I am currently working with the event display in the relays saved as booleans. So it would be nice to have a horizontal line reference. I made the vertical line with a Plotmodel.
LineAannotation and the horizontal line with majorgridlinestyle in the Y-Axis, but it can be done with a line annotation also. Learn more. Asked 2 years, 10 months ago. Active 1 year, 11 months ago.

Refer to the OxyPlot documentation for the full list of supported plot types. I also recommend downloading the OxyPlot source code and running the sample application. It showcases many of the plot types and features of OxyPlot.
You can easily modify the scripts from previous sections to show these new plots. The column plot shows you the data as vertical columns. The label of each category should be the ID of the beam.
To create the series, you first create a ColumnSeries object. Again, you are only interested in the non-setup beams from the plan. Finally, these items are added to the Items property of the series. This is the default look. Remember that you can change almost anything about a plot. For column plots, you can change things like their color, outline, and the space between columns. There is also a BarSeries object that shows the columns horizontally rather then vertically.
Then, update the AddSeries method to the following:. As before, you obtain the non-setup beams. Next, you create a PieSlice object for each beam, passing it a label in this case, the beam ID and a value in this case, the MU. You then add each slice to the series and finally add the series to the PlotModel.
The format of the outside labels is specified by the OutsideLabelFormat property of the PieSeries object. The format is specified as a composite format string, which uses placeholders that are replaced when displayed to the user. The placeholders representing numerical values can themselves be formatted to show or hide their decimal parts. In fact, the following example will show you how to plot the dose distribution of a plan as a color wash.
The DockPanel is another kind of panel, like the Grid, but allows its items to be docked or stacked in a specific way.
An interesting property of the DockPanel is that, by default, the last element is resized to fill any remaining space. Because the PlotView is the last element, it will be resized automatically as the window is resized.
The Slider will let the user choose the plane index of the dose matrix. The Value of the slider is data-bound to the PlaneIndex property of the view model. This means that as the user moves the slider, the PlaneIndex will be updated automatically.
The minimum and maximum values of the slider will represent the lowest and highest plane indexes. The heat map requires a LinearColorAxis, which describes how the colors will be shown. The x- and y-axes are the same as before, except for the titles. The z-axis, which represents the range of dose values as a color scale, will be shown above the plot AxisPosition.
The color scale can use any number of colors or palette to represent the range of values. The number passed to Rainbow is the number of color levels to use.
Finally, the maximum value of the axis scale is specified. Normally, this value is determined automatically from the data, But because the data will change as the slider is moved, the maximum value needs to be fixed for the entire dose matrix.
The x and y limits of the axes need to be specified.This tutorial demonstrates how to draw various charts including line chart, bar chart, column chart, area chart, scatter chart, and pie chart using WPF and C.
This article demonstrates how to draw charts using the WPF Toolkit. This toolkit may be a part of WPF in near future versions. After that, you need to add a reference to an assembly. To add a reference, right-click the References folder of your project in Solution Explorer and select Add Reference.
This action will open the Add Reference dialog as you can in the following Figure 1. On this dialog, select Browse option and browse the System. This assembly resides in the Binaries folder. Toolkit added to your References dialog as you see in Figure 2.
