Same issue as before, where the overlaid points are invisible.

thanks for the notice! I see I lost the bug fix when I pulled in some changes and merged to quickly from a fork that had not updated the latest changes. I have re-submitted the fix now.

Hello,

First of all congratulations for the excellent library! I searched a lot for WPF good charting libraries and I have finally found one!

I'm having an issue trying to plot the BarSeries example. The following exception is thrown: "The y-axis should be a CategoryAxis."

I don't know if I have got it right, but isn't the X axis supposed to be a Category axis? The y-axis would be a linear axis showing the values of each bar for each label, am I right?

Thanks for any help!

Bruno

EDIT: ok, when I run the project BarSeriesDemo it works... I don't understand why we have to set DataContext = this in that example (as it won't work without that line). Could I plot a bar graph the same way I plot a Line graph, i.e., something like this:

var plot = new PlotModel();
// create axes...etc...
var lineSeries = new LineSeries(myLabel);
// fills lineSeries with my Data
plot.Series.Add(lineSeries);
myGrid.Children.Add(new OxyPlot.Wpf.Plot { Model = plot };

The BarSeries is horizontal, the ColumnSeries is vertical.

I will improve the exception message to give more information about this.

It is also important to fill the category labels (the Labels list property, or an ItemsSource and a LabelField) with the same number of items as in the bar/column series. 

More documentation on this is coming later as soon as I get time. See the examples.

You need to set the DataContext in order for the binding to the plot model to work (this is standard wpf).

Thanks for the quick answer! ColumnSeries works fine for me!

I am very impressed of how easy an implementation of oxyplot is possible.

Many of my plots use a DateTime axis and I am used to change a monolor background to a background wth colored areas which represent the months for example (see the following example).

To implement this I created a new Annotation class "FreeAnnotation" and added two methods in order to be able to draw rectangles an text. This works fine but the annotation can only be added as "BelowSeries" oder "AboveSeries". So when drawing a rectangle as a BelowSerie then a grid ist hidden because it is drawn before the annotation.

So I changed the drawing order in "PlotModel.Rendering.cs from

this.RenderBackgrounds(rc);           
this.RenderAxes(rc, AxisLayer.BelowSeries);            
this.RenderAnnotations(rc, AnnotationLayer.BelowSeries);            
this.RenderSeries(rc);

to

this.RenderBackgrounds(rc);           
this.RenderAnnotations(rc, AnnotationLayer.BelowSeries);            
this.RenderAxes(rc, AxisLayer.BelowSeries);            
this.RenderSeries(rc);

But this is not a good solution because it has to be done with each new release.

My proposal is

• to change the drawing sequence of the two layers (RenderAnnotations(rc, AnnotationLayer.BelowSeries) and RenderAxes(rc, AxisLayer.BelowSeries) or
• to add additional postitions of the annotation layer (like "BelowAxes" or "AsBackGround" or "AboveBackGround") or
• to to add something like a "zIndex" whose initial values represent the order of the respective layer but it is a value which can be changed by program.

objo wrote at 2012-03-09 08:20:

I suggest we add "BelowAxes" to the AnnotationLayer enum and change to

this.RenderBackgrounds(rc);           
this.RenderAnnotations(rc, AnnotationLayer.BelowAxes);            
this.RenderAxes(rc, AxisLayer.BelowSeries);            
this.RenderAnnotations(rc, AnnotationLayer.BelowSeries);            
this.RenderSeries(rc);

This should not change the behaviour for existing plots

objo wrote at 2012-03-12 06:30:

I added "BelowAxis" to the AnnotationLayer enumeration. Included an example in the AnnotationExamples in the ExampleLibrary/ExampleBrowser.

ffiala, I'm doing a similar thing myself.   Could you please share your "freeannotation" class?

Hi

I am really new to your great OxyPlot.

I have a plot with more than one horizontal axes. Some of them are very small and the titles on the left side are clipped. How can I rotate the titles so that they are horizontal and not vertikal? I did not found how to do this.

Thanks

Michael

objo wrote at 2012-08-23 08:41:

Try the "Angle" property.

Note, there is an un-solved issue http://oxyplot.codeplex.com/workitem/9594-

For vertical axes, I would also like to implement http://oxyplot.codeplex.com/workitem/9972.

mreu wrote at 2012-08-23 09:56:

Hi objo

Thanks for the quick answer, but "Angle" rotate the labels of the ticks not the title or do I miss something?

Thanks

Michael

objo wrote at 2012-08-23 15:41:

Right, "Angle" rotates the labels of the ticks. Rotation of the titles is not yet implemented.

Do you want to rotate the titles of the horizontal (X) axes?

For vertical axes, the following feature is planned http://oxyplot.codeplex.com/workitem/9972.

mreu wrote at 2012-08-23 15:55:

Ho objo

yes, I need to rotate the titles on the left/right side. I have 9 LinearAxes (which are shown from left to right), some of them only show if it was activated or not. So I need the titles horizontal because they are truncated now.

Thanks

Michael

First, the compoment is amazing!!!!!
Thank you 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?
   

Axis with close button.

Multi tracker (show always)

fake legend
Everyone, I need your help!

Best Regards!
Lee

sorry, no support for images (yet). (need to find a good pattern to solve image loading on the different platforms supported)

Sorry, I cannot implement this right now.

But this project is open source - feel free to make a fork and propose a solution!
