In the attached graph, on the 2/9 x-axis reading the line is spiking up past the marker. I could make the marker larger/line thinner, however those options don't work well for this graph.

I've tried the three different LineJoin options, but none of them seem to modify the behavior I'm seeing.

The marker is placed at the proper location, I'm hoping the line would stop as well.

Ideas on things to try?

var weightLinePlot = new LineSeries ()
            { 
                DataFieldX = "Date", 
                DataFieldY = "WeightLbs",
                Color = weightGraphColor,
                MarkerType = MarkerType.Circle,
                MarkerFill = weightGraphColor,
                StrokeThickness = 5,
                MarkerSize = 5,
                LineJoin =  OxyPenLineJoin.Miter
            };

For the example code  belown, it's OK when dragging with right mouse button.

1) Uncomment "Here 2" or "Here 2", the same dragging will lead a strange behavior;

2) Uncomment "Here 2" or "Here 2", comment "Here 1", the same dragging will be OK;

So,  is there a bug for PlotType.Cartesian and right mouse button dragging?

Here is the example code:

var pm = new PlotModel("Test")
            {
                PlotType = PlotType.Cartesian,                      // Here 1
                Background = OxyColors.White
            };

            //pm.PlotMargins = new OxyThickness(40, 40, 40, 40);    // Here 2

            LinearAxis la = new LinearAxis();
            la.Title = "Pressure";
            la.Position = AxisPosition.Left;

            pm.Axes.Add(la);

            DateTimeAxis dateTimeAxis = new DateTimeAxis();
            //dateTimeAxis.Title = "Time";                          // Here 3
            dateTimeAxis.StringFormat = "yyyy-MM-dd HH:mm:ss";

            DateTime dt = DateTime.Now;
            dateTimeAxis.Maximum = DateTimeAxis.ToDouble(dt.AddMinutes(15));
            dateTimeAxis.Minimum = DateTimeAxis.ToDouble(dt.Subtract(new TimeSpan(0, 15, 0)));
            dateTimeAxis.CalendarWeekRule = CalendarWeekRule.FirstFourDayWeek;

            dateTimeAxis.Position = AxisPosition.Bottom;
            pm.Axes.Add(dateTimeAxis);

            plot1.Model = pm;

Yes, you are right there is a bug when panning cartesian axes, it should hopefully not be too difficult to fix (it was working properly before).

ps. Are you sure you want to use a cartesian coordinate system with the datetime axis? The way it is implemented means that 1 unit on the pressure axis will be the same length as 1 day on the time axis.

Of course not, I just happenly found this bug.

the problem is related to the automatic adjustment of plot margins. Try to set AutoAdjustPlotMargins to false until we have solved this problem.

Hello,

Firstly, congratulations and thank you for this super project. and thank you for sharing that !

I have a question about the Plot class in OxyPlot.WPF namespace.

Due to InvalidOperationException ("This PlotModel is already in use by some other plot control.") ,

,it is not possible for several plotControls to have the same PlotModel. Is there a reason to this choice ?

I thought that could be interesting to have the possibility to represent several plotControl to different location of an application, all bound on the same PlotModel.

In this case, the code in the OnModelChange() method would be :

 if (this.Model != null)
                {
                    if (this.Model.PlotControl == null)                    
                    {
 
                        this.Model.AttachPlotControl(this);
                        this.currentModel = this.Model;
                    }
                }

What do you think about that ?

Thank you very much.

objo wrote at 2012-07-12 12:59:

The PlotModel is a "ViewModel" for the Plot - currently a lot of view-specific data is stored in there(e.g. axis scaling, coordinates transformed to screen space) , and it cannot be used in more than one view. I prefer to keep it this way (could of course also make the PlotModel contain only plot data, and a PlotViewModel containing the view specific data, but I think this would be more work...)

Patoon wrote at 2012-07-12 13:36:

Ok, I understand.

In this case, imagine the following scenario:

We have a UserControl hosting a PlotControl (with binding on a PlotModel), this UserControl DataContext is bound on a ViewModel called myVm (this ViewModel has so a PlotModel property)

For you, what would be the best way to reuse an other instance of this UserControl but bound on the same ViewModel instance (myVm) ?

Thanks.

objo wrote at 2012-07-13 09:40:

I would not reuse the same instance of the view model in different views. Can you create different instances?

Patoon wrote at 2012-07-13 10:50:

Indeed, even if my view model receive some modifications before display the new userControl, I think this is the most reasonable solution.

Thank you.

Hi,

I have a question that is directly related to this subject.
I have a viewmodel that contains an ObservableCollection of PlotModel. This collection is binded on the ItemsSource property of a ListView. For displayinf charts, I use a datatemplate. Here is my XAML :

 <ListView ItemsSource="{Binding PlotModels, Mode=OneWay}" ItemTemplate="{StaticResource ResourceKey=NamedCacheStatsTemplate}">
         <ListView.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapPanel Width="{Binding (FrameworkElement.ActualWidth), RelativeSource={RelativeSource AncestorType=ScrollContentPresenter}}" 
                                   ItemWidth="{Binding (ListView.View).ItemWidth, RelativeSource={RelativeSource AncestorType=ListView}}" 
                                   MinWidth="{Binding ItemWidth, RelativeSource={RelativeSource Self}}" 
                                   ItemHeight="{Binding (ListView.View).ItemHeight, RelativeSource={RelativeSource AncestorType=ListView}}" />
                </ItemsPanelTemplate>
         </ListView.ItemsPanel>
 </ListView> 

<DataTemplate x:Key="NamedCacheStatsTemplate" DataType="{x:Type oxymodel:PlotModel}">
        <oxy:Plot Model="{Binding}" MinHeight="300" MinWidth="600"/>
</DataTemplate> 

My viewmodel retrieves statistics from a webservice every 5 seconds, updates the existing plotmodels in the observablecollection of plotmodel, and call RaisePropertyChanged("PlotModels") for updating the UI. When the UI is updated, the exception InvalidOperationException ("This PlotModel is already in use by some other plot control.") is thrown.

Is there something wrong in my usage of OxyPlot, or, is there a workaround for this problem ?
Thanks in advance for your reply,

Best regards.

Is this the same bug as in http://oxyplot.codeplex.com/workitem/10000?

Otherwise we should create a new issue.

Hi,

It seems that only reloading the chart control causes this error. For instance, I use the Avalon Docking framework and whenever I switch from one tab to the other or float/dock a panel, I get this error. Is there any way to disable this check in the code? 

Thank you.

objo wrote at 2012-12-03 07:38:

Please test the latest version. I checked in a change Nov 23 related to loading/unloading the WPF control, I think this is the same problem as you encountered. I have tested the latest version with AvalonDock without problems.

Hello:

Since OxyPlot no ToolTip feature currently, so I was trying to use TrackerFormatString of LineSeries to show data point information but I failed (I am using Silverlight). for example I have an object like the following:

Class myObj
{
  int x;
  int y;
  double status;   //I need this status show as a status string after calculation by a method when mouse click or hover current point
}

LineSeries only show X, Y, so I tried ScatterSeries (I actually need LineSeries but not ScatterSeries), but ScatterSeries still can not show a method converted string in TrackerFormatString.

So is there any other solution? Am I using wrong way? 

Thanks!

objo wrote at 2012-09-16 11:37:

try adding a public property to your class

public double Status { get { return status; } }

and set the TrackerFormatString of the LineSeries to something like "{Status:0.00}"

I will add an example later. Note that the status values will not be interpolated if you click between points.

tony_codeplex wrote at 2012-09-16 17:12:

Thanks! objo.

Waiting for your example...

please note I need to show x, y and status string (currently I only need show 3 data, but maybe more in the future, i mean, is it possible show all object properties using LineSeries? ) on my screen when mouse click or hover. 

and, my status string is not simple like "{Status:0.00}", the status handle method similar like the following code:

public string GetStatusString(double status)
{
   if((status & FLAG_A) == 0)
{
   return "Status A";
} 
else
{
  if(status & FLAG_B) == 0)
      return "Status B";
  else
 {
    switch(AnotherProperty)
{
  case xxx:
     if(stauts & ..)
      return "Status xxx";
     break;
   case xxxx:
      ...
    break;
} 
} 

} 
return "Status Fail"; 
} 

so do you think is it possible to implement using oxyplot LineSeries ?

Thanks!

tony_codeplex wrote at 2012-09-16 20:07:

Hi objo:

I got it just now!

I did not know I could use  object's property directly like "{Status}" in TrackerFormatString, all existing examples just show "{0}", "{1}", "{2}".....

It is very helpful!  Thank you very much!  OxyPlot is really great!

BTW: I think there is not ONLY me don't know this usage, hope they can get help from this post too.

Do you mean like this? This is one Plot object with 3 series on 3 axes and since they are in the same Plot, they zoom/pan/etc. together.

So separate boxes are not supported, I see.
Can the above AxesDemo plot also be modified to include multiple x-Axes, i.e. like the plot below, to make the separation a bit clearer?
