Hi! Thank you for oxyPlot, it's really amazing))
Im working with real time data and sometimes get strange error:
System.NullReferenceException: in OxyPlot.Annotations.Annotation.Transform(DataPoint p) в c:\TeamCity\buildAgent\work\3b9fcf1ba397d0ed\Source\OxyPlot\Annotations\Annotation.cs: 115
I'm using arrow anotations and check everything before adding it to the plot view.

This looks like a problem with the x-axis.
Are you adding the arrow annotation to a plot without axes/series? What platform are you on? Can you add some code that reproduces the error?

New Post: Tracker binding for barseries

WPF?
There is a TrackerChanged event on the PlotModel. I don't think we have exposed any bindable properties or a routed event for the tracker in the PlotView control. Maybe this should be added?

The file should be in Source/OxyPlot.Wpf. Let us know if you find a bug!

I don't think this is currently possible.
We have a similar feature request in https://oxyplot.codeplex.com/workitem/9192

How is this defined in mschart?
Could we add a LegendGroup property to the series? Then define how the legend groups should be presented in the plot model.

Did you see the example RectangleBarSeriesExamples in the ExampleLibrary? I think it should be possible to use it with DateTimeAxis and CategoryAxis - just use DateTimeAxis.ToDouble to convert the DateTime values to numbers. And please create an example we can include in the ExampleLibrary!

Thanks for reporting a possible bug - I'll try to reproduce this! I cannot see any errors in your Activity class, it looks ok to me.

The Update method was recently removed from the public API because it should not be called by the client apps, only by the PlotView controls.

Synchronize
- the position of a specified value (e.g. 0)
- or the position of a specified value (e.g. 0) and the scale (with a multiplier)
of all axes in a 'synchronization group'
(panning/zoom will change all axes in the group at the same time)

I'm using wpf. There are dateTime and value axeses in my model (dateTimeAxis as x-axis), and there are couple line series too) Here is the code the annotation adding: 
   var arrow = new ArrowAnnotation();
   arrow .Text = info;
   arrow .StartPoint =  new DataPoint(DateTimeAxis.ToDouble(currentTime), value- value/ 100000);
   arrow .EndPoint =  new DataPoint(DateTimeAxis.ToDouble(currentTime),value);
   PlotModel.Annotations.Add(tradeToDisplay);
Thanks)

The transforms on the axes are defined when rendering (since they depend on the width/height of the client area). Are you trying to transform before the plot is rendered? Maybe you can subscribe to the Axis.TransformChanged event and do this after the transform has been set?

Is this an old Windows version? XP? Then I think you need an update for PCL support.
http://support.microsoft.com/kb/2600211

If you want to run the library without patching you must build OxyPlot yourself - you can change the build target framework for the OxyPlot .NET 3.5 solution.

Can this be a race condition? Can you try locking the PlotModel.SyncRoot when changing the model?

I've been reading the source a bit when I've had free time trying to think of a good way to put it together myself, but had other things require my attention at work so I haven't really put a lot of time into it yet sadly.

They've actually asked me to make a generic custom control at work that will let them add axes and series through the designers properties browser, as well as include the annotation toolbar and a custom legend (it lists all axes and series in the plotmodel with visibility checkboxes and colour buttons for the series pic), so I'll probably end up taking some time to rework it into a proper mvc pattern for that and submit it afterwards. I'm just reading up on proper implementation of a custom control, properties and such in winforms (although it's kinda hard finding a good post on the subject after 2005ish, was hoping to find one with C# 4/5 features). It'll hopefully be pretty generic (although winforms based) so I'd be happy to submit it if It'd be useful.

First, the compoment is amazing!!!!!
3Q for your effort.

I have some questions:
  1. I want to implement Drag & Drop operations. But I have no idea.
    I want to Drag LineSeries(by drag the legend) from a PlotView to anthoer, and then the original PlotView was closed.
    should I operate PlotCommands and PlotController?
  2. If I want to add close button in the Yaxis(when a plotview has many LineSerieses), how should I do ?
  3. If many LineSerieses in a plotview, how track the point?
Image

Everyone, I need your help!

Best Regards!
Lee
