Strange behavior of XAML polar demo

Hi, objo. In your WPF/XAML examples the polar demo (Defined in XAML) behaves strange. If you click with the right mouse onto the plot and move the mouse the plot is rotated. Fine. But there is also a change with respect to the magnitude axis. I think that this is a bug or how do I have to interpret this? Moreover, if you zoom into this plot, you will get more spiral cycles than there should be.

objo wrote at 2012-08-29 06:35:

Right, zoom and pan is not properly implemented for polar plots yet.

Hi

I build a plot with multiple axes (like the on in the axes demo) and I have a single serie for each of this axes, but all series are shown in the first axes. How to show the series in the corresponding axes?

Thanks a lot

Michael

xyseries have aixs key property,you can set axis key

Strange axis working?

szs_szs vor 9 Jahren • 0
I have strange problem with Axis how i think. I am trying to save Rectangle size and place with any axis. At first I am converting data points to screen points using Transform, then I save them converted points, after axis changing I am making Inversetransform of saved point's.
ChangeAxis- Transforms, saves, changing axes.
SetNewRectangle - Set new rectangle from saved points using InverseTransform.
The main question is why it's working when I am clicking ChangeAxis and then OldRectangle and not working when I am clicking on button "MakeAll" (encapsulates ChangeAxis,OldRectangle).

Someone help me ?

Thanks ! :)

Hi,

I'm trying to add a DateTimeAxis to a PlotModel using the OxyPlot.Wpf.DateTimeAxis and OxyPlot.PlotModel.

I'm getting an error since the DateTimeAxis is not derived from Oxyplot.Axes.Axis:
out of OxyPlot.Wpf Source:
public class DateTimeAxis : Axis
in here Axis is: OxyPlot.Wpf.Axis

Error: This PlotModel is already in use by some other PlotView control.

Alireza Jahanshahlo vor 10 Jahren • aktualisiert von anonymous vor 10 Jahren • 1
I have two tab bind to one viewmodel which contain a PlotModel and view model selected through a DataTemplate.
When click on the first tab the viewmodel was bind properly but when switch to second tab above exception throw.
All of control is same in two tab.
Is it possible bind one object to two controls?

How to configure the Click Event

Hello people,
I'm using OxyPlot in a Windows 8 Metro App. When you click, for example in an area chart or a line chart, it appears a label with the values of the chart. The point is, can I change the event when I click by simply passing the mouse over?

Thank you. ^^

everytimer wrote at 2013-08-21 21:00:

That is not supported by the library right now.

Redzar wrote at 2013-08-22 10:04:

There is no way to modify de code and make it? :_(
What is the name of the label?

objo wrote at 2013-08-22 10:30:

It should be possible to set the DefaultTrackerTemplate property to null.
I will submit a fix that hopefully corrects this, will be available at nuget/download later today.
The same behaviour should be implemented on WPF/SL.

Redzar wrote at 2013-08-22 10:52:

Thank you very much!!
Please could you explain how to do it then? ^^

objo wrote at 2013-08-22 20:42:

I checked that this also work on WPF/SL.
Try to set DefaultTrackerTemplate={x:Null} on your Plot control.

Redzar wrote at 2013-08-23 10:10:

Hi Objo,
I downloaded the update and I set the Plot control like this:
<oxy:Plot Model="{Binding PlotModel}" DefaultTrackerTemplate="{x:Null}" Margin="10" BorderBrush="Transparent" Background="{x:Null}" />
But it doesn't work. The label doesn't appear clicking or moving the mouse.
Any idea?

Thanks ^^

everytimer wrote at 2013-08-23 12:26:

I think that disables the Tracker...

Redzar wrote at 2013-08-26 09:47:

So what do I do? My boss will kill me XD

objo wrote at 2013-08-26 11:14:

Redzar: not sure about what you are asking for, I guess I misunderstood - yes, setting the tracker template to null disables the tracker.

Redzar wrote at 2013-08-26 11:20:

I just want that when you pass the mouse over the chart, the Tracker is displayed automatically, without having to click.

Sorry, I don't understand that post.

Sorry, I don't think it is possible to show the tracker on mouse-over in the current version.

Oki,
Objo, you know where could be the part of the code that would make it possible to try to do it myself? ^^

Axis.MouseDown / Area Property

alex vor 9 Jahren • aktualisiert von Mark Bean vor 3 Jahren • 5

Hello,

I have tried to add a Event Handler for the Axis.MouseDown Event, but it doesn't get called!

FrequencyAxis.MouseDown += (s, e) => {

IsFrequencyAxisFixed = !IsFrequencyAxisFixed;

};

Also, would it be possible to add a Area property to the Axis? (Like the PlotModel.LegendArea or PlotModel.PlotArea)

UpdateMaxMin

Mark Bean vor 9 Jahren • 0

New to OxyPlot and OpenSource coding. Have plotted some LineSeries, altered mousing to zoom in and out, but would like the plot to normalize the data being plotted as we zoom in. To do this I need access to MaxY of the data series (see also UpdateMaxMin()). Easy to calculate and implement, but I see that OxyPlot has protected internals offering this already, only I cannot access those from an Example to normalize the data. Is the correct approach to inherit fom a class that implements and exposes this and use my inherited class rather than LineSeries? 2nd, is there a good reason why such integral properies are internal and protected, not public? Sorry if this is a stupid question.
