Hi Objo,
I want to create a graph like in the image .

When i see OxyPlot, thought this can help me to create the graph. Unfortunately, i don't know where i must to begin.
Need advice to create the graph. 

Thank You,

objo wrote at 2012-08-09 00:23:

this looks like annotations - try to add PolygonAnnotation, ArrowAnnotation, TextAnnotation and LineAnnotation to the Annotations collection in the plot model.

And the Blue/orange lines are series? Add LineSeries to the Series collection.

See the examples in the 'Example browser'.

thank you for quick respon .

i was try to create using PolygonAnnotation . but i have problem with PolygonAnnotation.Points ..

Actualy i try to convert C# Script to PowerBuilder.Net 12.5 script but i am stuck at PolygonAnnotation.Points , i can't find add function .

There's other way to add value into PolygonAnnotation.Points , or how to create PolygonAnnotation by wpf xaml like LineAnnotation in example .

objo wrote at 2012-08-09 08:50:

Right, I should probably change the PolygonAnnotation.Points from IEnumerable to IList. Now you have to create a new collection, then assign the Points property to the collection.

putra_wlh wrote at 2012-08-09 11:31:

thank you for your response .

I will try to create a new collection. But i don't know it will worked or not .

Hopefully i can use a new update from oxyplot for this issue .

best regards,

The type of the property has now been changed.

I'm happily using the reporting module and I find very useful.

I'd like to be able to specify a default style for the whole table (for the docx export) and not for the text inside the table.  Is it possible?

Also, is there a way to put some content (other than text of course) inside a cell of a table? My intent is to keep multiple charts aligned in my docx document.

objo wrote at 2012-10-16 23:55:

Great to hear that you find the simple reporting classes useful! 

Do you need to set spacing/indentation? Or other table properties? It should be possible to add such a style for the table elements, and I think this could be supported by all the output formats (html, pdf, xps, docx)

Note that this reporting model was designed to be *very* simple, so currently the table cells can only contain text. I will refactor to a more flexible model later (I would also like to have more control of the inline content of the paragraphs).

Check out the OpenXML SDK if you need full control of your docx output. http://www.microsoft.com/en-us/download/details.aspx?id=5124

AleV wrote at 2012-10-17 15:18:

Thanks objo, as far as I understand of your object model, a OxyPlot.Reporting.ReportStyle only specifies the font family of the text, the text of the table or the text of the table headers and they are all "Paragraph Styles".

As you probably know in Word a Style there are different type of styles ("Paragraph", "Character", ..., "Table"): what I'd like to be able to do is to format a table with a table style (for example by applying the Word 2010 built-in "Light Shading - Accent 5 style"), rather than with a paragraph style for the content of the cells. But maybe this is something too specific to docx (or HTML): I have no idea if this also applies to tex, xps or pdf.

Finally, is it possible to put content in the header and footer of the document?

Anyway, thanks a lot for your beautiful software.

objo wrote at 2012-10-17 15:37:

Yes, the style is only defining paragraph properties. I see some refactoring may be necessary.

I would like to add a feature that creates the document from a Word template file, then I think it should be possible to put all Word-specific styles in there. It should also be possible to add headers and footers (including graphics) in the template file. I have added the feature in http://oxyplot.codeplex.com/workitem/10011

Sorry, I don't have time to implement this right now. But I need it myself in a couple of months from now :)

Hey,

Quick question. How can I make a chart that has two lineseries that have very different scales? How can I assign different y-axis to the two respective lineseries?

Thanks in advance.

objo wrote at 2011-11-07 22:26:

see the Amdahl's law example in the Example browser. Set focus on the OxyPlot control and press Ctrl+Alt+C. Paste the source into your code.

Define two vertical axes (at different positions or with different position tiers) and define a Key for each axis. Set the LineSeries.YAxisKey to select which axis to use.

philmo74 wrote at 2011-11-08 15:53:

Great that works!

Didn't know you could copy paste the code.

Cheers

he everyone:

   i need draw 10000-20000 rectangles (color fill) in my wpf appliction (similar  pixel in bitmap ).

the app will became slow , there is a good solution  for draw-heavy  appliction.

i find oxyplotwpf render graphic in ShapesRenderContext, it perform well when  plot element

count is little,  i want to try use drawingRenderContex instead of shapsrenderContex, but i have not success. anyone can help me, thanks in advance

objo wrote at 2012-08-21 13:27:

I did not see any significant performance improvement in the DrawingRenderContext, so this code was just left there in case it should be reviewed again.

I guess you want to plot heat maps? I think it is necessary to support bitmaps in the IRenderContext to get good performance for those. See http://oxyplot.codeplex.com/workitem/9801

ProCodeMyth wrote at 2012-08-23 02:22:

very thank objo,

   your guess is exactly what i want to do, i recently study geogological map , i need fill many fill rectangles with color which represent　lith info,   so  i need an way to quick draw , bitmap buffer(bitmap render) is an great idea,  but in wpf  i dont know how to implement ,  WriteableBitmap may help me .

objo wrote at 2012-08-23 08:53:

In WPF it should be easy to implement a heat map using BitmapSource.Create. I think this will have better performance than drawing on a WriteableBitmap. Create a 256-color palette and a pixel array (scaled to 8-bit) from your lithology data. Wrap the image in a WPF ScrollViewer and use a WPF scale transform if you want to zoom in/out!
