Hi,
I am using OxyPlot to achieve few line charts using WPF C#.
Using XML :
I had created Logarithmic & Linear axis as Left & Bottom respectively and 5 line series in xml respectively. I assign each line series ItemSource as List<Point> and it works well.

Now I am to create the same thing dynamically,
I could create both axis properly. And for line series, I add it to the PlotModel as below :

    public void AddData(List<List<Point>> data, string title)
    {
        LineSeries lineSeries;
        int ctr = 0;
        foreach (List<Point> set in data)
        {
            ctr++;
            // Setting the itemsource as set i.e. List<Point>
            lineSeries = new LineSeries { StrokeThickness = 5, MarkerSize = 3, Title = title + " " + ctr, ItemsSource = set };
            PlotModel.Series.Add(lineSeries);
        }
    }

With the above code, I get the plot, 5 titles, but no lines - I guess because somehow data is not set to Points of the line. I also tried :
lineSeries.Points = set;
but this could do as it doesn't accept List<Point>

Why is this difference between creating thru XML and code ? Why their are no lines visible ? Do I need to set or pass data in some other format ?

Can anyone please help me.

I got the solution,
I need to set DataFieldX = "X", DataFieldY = "Y" in my LineSeries along with ItemSource.

Thanks

I want to add a bitmap image to the plot. I have a bitmapimage, which I made from a matrix. I want to know how to add this image to oxyplot? I made scatterseries , but it got too slow.

I made a plotmodel, i am not able to add oxyimage to plotmodel.

I looked at this. But I could not get rendercontext of the model.
Edit:

I made OxyImage and added to model using image annotation:

                model.Annotations.Add(new ImageAnnotation
                {
                    ImageSource = image,
                    X = new PlotLength(.5, PlotLengthUnit.RelativeToPlotArea),
                    Y = new PlotLength(.5, PlotLengthUnit.RelativeToPlotArea),
                    Width = new PlotLength(.5, PlotLengthUnit.RelativeToViewport),
                    Height = new PlotLength(.5, PlotLengthUnit.RelativeToViewport),
                    Opacity = 1,
                    Interpolate = false,

                });

I see the image, but it doesnt zoom or move.

This bitmap is an rgb image created from bytearray.

any input is deeply appreciated.

thanks a lot

well, this part is fine. i will post another issue that i am facing. thanks

Hi!
For legal reasons we need to know:
What is the ECCN code for OxyPlot?
and Are there any cryptos used?
Regards
Emelie Edström

There is no code depending on System.Security.Cryptography in OxyPlot.
Sorry, I don't know anything about ECCN codes.

No, there should not be any parts designed in US. This library is made in Norway.

Hi,

Is it possible to adjust the orientation and position of ArrowAnnotation's Text like that of LineAnnotation. My horizontal ArrowAnnotation's text cannot be seen as it starts from X=0 and the text is fixed behind the tail :(.

Thanks.

Currently the ArrowAnnotation only support horizontal text.

I would like to create a ChartController for a plot with multiple series. The ChartController would contain items similar to a legend but with a checkbox next to each series. The checkbox would allow the user to toggle the visibility of the series. How should I implement this? How can I display a short segment of the line in a listbox?

(I edited the title to make it easier to search in the discussion threads)

Check boxes and list boxes are not supported by the OxyPlot core - you need to define these in an overlay.
This should be included in the examples, I have created an issue:
https://oxyplot.codeplex.com/workitem/10122

I'm not sure what I'm seeing here, thought I would ask and see if anyone else is seeing this.

Xamarin.Android column series, I setup a value axis with the following parameters:

var valueAxis = new LinearAxis { Position = AxisPosition.Left, MinimumPadding = 0, MaximumPadding = 0.06, Minimum = 260, Maximum = 265 };

The plot does not draw, and I get this in the debug output window:

07-13 14:24:50.911 W/OpenGLRenderer( 3926): Path too large to be rendered into a texture

Oddly, if I back down the Minimum to 100, graph draws fine, but when I do a two finger zoom in the graph fails to draw and the output window starts outputting "Path too large..." errors.

I'm a bit stumped on what is going on here or what I might do to correct it, thoughts?

Hey I'm seeing this gaps between my lines:


Do you know what am I doing wrong or if this is a bug?

Thanks.

I've used older versiones of OxyPlot a lot and never experienced that issue. Could you provide the data to test it myself? It seems to me that your data may have duplicate points (or nearly duplicate) there.

Edit: If you have some point that is Undefined or his y-value is NaN you may experience a gap as yours. Are you doing mathematical operations (divisions) with your data?
