Direct3D 10 Renderer fork of OxyPlot, I've done it

Sergey Popov 3 years ago in New features • updated by Ss Oi 2 years ago 6
69ms vs 623ms per frame on two StairStep series with 35182 points each, approx. 1.6Mb of binary data

Works only on Direct3D10, but I assume it can be ported to Direct3D9

The problem is: I want to contribute to OxyPlot, but I guess I'd better put an opensource fork with credits, so someone can port rendering from it to Oxy. Rendering is kinda heavily optimised now, all up to LineSeries itself, and I will continue to get rid of unnecessary stuff. Right now actual rendering is mostly carried out by geometry shaders. I push raw points' data in screen coords to the vertex buffers as line lists and strips, and shaders process it into triangle stripes. Now, for example, I'm moving line clipping routines to the vertex shader stage frustum culling. I'd like to move screen coords transformation to the shader stage too in the nearest future.

So stay tuned, major performance breakthrough for OxyPlot is near.

Image exporters for headless environment

Francois Botha 3 years ago in New features • updated 3 years ago 4

I need to generate plots, save them to images and embed them in emails, all in a Windows service app, i.e. I have no dependencies on any UI libraries. I'd prefer to keep it that way and I don't want to reference Windows Forms, WPF or one of the other UI frameworks.

It should be possible to export to PNG by using just System.Windows.Drawing and package that all up as e.g. OxyPlot.Headless.

Rectangle Annotation text wrap

Nick Heath 4 years ago in New features • updated by anonymous 4 years ago 1
At the moment, if the text in a Rectangle Annotation (and I assume all other annotations) is larger than the bounds of the annotation, the text is simply truncated. Is there any way to force the text to wrap onto a new line?

How to reset zoom

helpme 11 months ago in New features 0

I have an oxyplot RectangleBarSeries and a button "Reset". When I press the button I want the zoom to reset (in the same way the zoom resets when A is pressed on the keyboard). I've tried the ResetAllAxes(); function, but it doesn't work. Is there any other way to achieve this? 


negative axis step

Gsword 12 months ago in New features 0

I have been looking for a way to invert an axis (smallest value in the top, largest in the bottom).


LinearAxis la = new LinearAxis()
                    AbsoluteMaximum = 10,
                    AbsoluteMinimum = 1, MinimumMajorStep = -1, IntervalLength = -1, MajorStep = -1

Oxyplot fails if max < min or step is less than 0 (exception).

It would be nice if this was possible

Plot filled circles with specified intensities and locations

dyeung 2 years ago in New features 0

Can I plot filled circles with user specified intensities (gray scale) and locations with current implementation? If not, any example how to extend the rendering model? Thanks.
