I'm writing this application that will need to display a number of line graphs, so I tried to implement something along the lines of your WPF example.

However, the LineSeries() constructor doesn't accept any arguments and the class doesn't seem to have a Points property.

I downloaded OxyPlot through NuGet and am using VS 2012.

What am I missing here?

Thank you in advance.

Create an OxyPlot.PlotModel and add a OxyPlot.LineSeries to access the Points collection.
The Points collection is not available in the OxyPlot.Wpf.LineSeries wrapper class (in this case, use the ItemsSource property)

Thanks for the quick reply, it brought me to the solution.

There was no OxyPlot.LineSeries, but upon messing around I found OxyPlot.Series.LineSeries. And it has the Points collection.

I now have a basic graph drawn in my application, awesome.

On a completely unrelated note, is using this technique to draw up a bunch of points bad practice performance wise? I have a number of images and am displaying intensities in their pixels, so there will be a lot of points added to each graph.
