Hello.

So I am using the Example Browser application, and I have pasted the code to VS 2013, like so:



I understand that the return type of the Notinterpolatedvalues() method is a PlotModel. Now - how do I display that? As in, what is the method I need to use in my main method in order to play Notinterpolatedvalues()?

Thank you.

I'd like to make a linechart over a stream of numbers that continuously get's generated. Sort of like a cpu-usage graph or something along those lines; where the new data enters on the right side, and the old data exits on the left. Also, I do not know beforehand the maximum number that will be generated in this series (but I do know it will never be below 0). What I tried so far was something like this:

        private class NetworkPlotModel : PlotModel
        {
            private LineSeries ups, downs;
            private LinearAxis vax;
            public NetworkPlotModel()
            {
                Axes.Clear();
                Axes.Add(new TimeSpanAxis(pos: AxisPosition.Bottom, title: "Time", min: -60, max: 0));
                Axes.Add(vax = new LinearAxis(AxisPosition.Right, "Value"));
                vax.MaximumPadding = 0.03;

                Series.Add(ups = new LineSeries(OxyColor.FromRGB(1, 0, 0), strokeThickness: 3, title: "Up"));
            }

            public void Push(TimeSpan delta, double up)
            {
                for (int i = 0; i < ups.Points.Count; i++)
                {
                    IDataPoint p = ups.Points[i];
                    ups.Points[i] = new DataPoint(p.X - delta.TotalSeconds, p.Y);
                }
                ups.Points.Add(new DataPoint(0, up));
                this.Update(true);
            }
        }

However, this does not seem to draw a line at all (even though I call the Push-method 1 time, 100 times or 1000 times, and I've also tried to call it once a sec, and up to 10 times a second).

Could I please get an example of how to make something like this work?

I implemented something similar using an observable. Here is the code below, which might give you a few hints.

Random rand = new Random();

Observable.Interval(TimeSpan.FromSeconds(0.1)).Where( x => x < 100).Subscribe( x => 
		{
			var series = ((LineSeries) pm.Series[0]);
			
			if( x > 50)
			{
				// Remove the first point in the series when we readh 50 data points.
				series.Points.RemoveAt(0);
				
				// Reset the minimum value on the xAxis.
				pm.Axes[0].Minimum = series.Points[0].X;
			}
			
			// Add the new point
			series.Points.Add( new DataPoint(3 + x, rand.Next(10)));
			
			// Set maximum value
			pm.Axes[0].Maximum = x;
			
			// Need to reset the xAxis for it refresh properly
			((LineSeries) pm.Series[0]).XAxis.Reset();
			
			plotControl.Refresh();
		}
	);

I think the PlotModel class also has a .Refresh() method.

PlotModel.Update updates the model, but does not refresh the plot control.

Use PlotControl.Refresh or PlotModel.Refresh to redraw the plot.

Will add examples on the wiki page http://oxyplot.codeplex.com/wikipage?title=Refreshing%20a%20plot

Hi, objo!

Сan You look at this screenshot? 

May I get rid of this?

objo wrote at 2012-06-19 12:24:

First guess: Try to change the LineJoin property on the LineSeries from Miter to Round.

Thank You! Works well!

I'm using OxyPlot.WindowsForms and VS 2010 Ultimate.

I'm trying to add Control Plot but in Controls Menu there is no such thing like "Plot"!

Help!

objo wrote at 2013-01-12 17:58:

• Right click in the toolbox
• Select "Choose items..."
• Press "Browse..." under ".NET framework components
• Select the OxyPlot.WindowsForms.dll assembly (note that there are versions for both .NET 4.0 and .NET 4.5)
• The "Plot" control should appear under "OxyPlot.WindowsForms Components" in the ToolBox

Thank you for your response. That helped , I had to download the metro stuff again and I from the xaml file. I took the commands from it for oxy and inserted in my xaml file and these commands were recognized ok. However when I executed the code with my vb code , no graph came up. I was expecting to see at the axes of the graph. Do I need the other xaml files you have in the BasicSample directory also? I also noticed that the BasicSample directory did not have a Project file so I could execute the project - is it supposed to be like that? in my VB project I have a Visual Basic Project File that I click on to start the project. Is it possible that I am not executing the right oxy commands in my vb code. I am posting the code here again.

 Dim plotControl As New OxyPlot.Metro.Plot
        Dim plotModel1 As New OxyPlot.PlotModel
        plotModel1.Title = "Outside"
        plotModel1.Axes.Add(New LinearAxis(AxisPosition.Bottom, -20, 80))
        plotModel1.Axes.Add(New LinearAxis(AxisPosition.Bottom, -10, 10))
        plotControl.Model = plotModel1
        plotModel1.RefreshPlot(True)

//xmlns:oxy="using:OxyPlot.Metro"

//<//oxy:Plot Model="{Binding PlotModel

 code I put in my xaml file 

//}"/>

I just checked out the source-code and built, what I assume are the Oxyplot libraries.

There is a project called "Oxyplot.Tests", which I assume contains the unit tests for this project. What tool do I need to use to run them? Or rather, HOW do I even run the tests?

The code does not look like nUnit or xUnit stuff to me.

Puzzled,
chronodekar

objo wrote at 2012-07-13 09:35:

the *.Tests assemblies contain standard NUnit tests.

Note that some of the tests are asserting on images. I have not checked in the baseline of the plot bitmaps (*.png). The baseline is generated first time the tests are executed.

chronodekar wrote at 2012-07-13 12:35:

Ah, thank you for your reply! I opened the files "OxyAssert.cs" and "TestModels.cs" from the upper level in Visual Studio. There were no [Test] attributes or even [TestFixture]  in them and I was wondering if I missed anything.

After reading your reply, I went digging a bit deeper and found Axes/AxisTests.cs which has something I'm familiar with. :)

I'm trying to understand the code base - at least at a very high level initially, before digging further. Any suggestions on where I should start?

objo wrote at 2012-08-08 23:17:

To understand the code base, I would look at the PlotModel, LineSeries and LinearAxis classes (and ancestor classes). See the PlotModel.Render method, that's the 'main' method of the plots!
