Axis SetRange problem

Hi,
I'm using the actual V7.2 controls.
There is a problem if SetRange for an xAxis is used if both parameters are negative.

Example:
chartAxisX.SetRange(-20, -18);

The axis will be set to "-20, 0". If I move the axis by mouse it works, just the SetRange command fails.

Best regards,
Jürgen

Texture Dynamic

Hi, I'm working on a new version of our software for data visualization. In one mode is a CCD camera the source for images. I want to display the images as fast as possible. I saw some Direct3D examples where images coming from a web-cam were displayed in realtime using a dynamic TextureBuffer. For ...

Re: Problem with chart creation

I fixed the problem:
The SplashWindow was the main window in the Application.
After creation of the MainWindow it has to be set as Applications MainWindow also by

App.Current.MainWindow = this;

Then everything works.
It's new in Version 6, in V5 it wasn't necessery... so I was a bit confused.

Re: Problem with chart creation

The Splash-Window is opened first. The Main-Window is started by the Splash-Window.

Initialization of a chart is done later when some data should be shown.
The strange thing is: It works at my laptop - at 3 other pcs the problem occurs.

Hi, Sorry for delay. I prepaired a Test-Project and everything works for this. I checked the "big" project where it doesn't work. The splash-window makes the problem.

Hi, I used V5 LightningChart inside a docking suite (Actipro). Now I changed to Version 6 of LC. When I open a new Document in docked state the chart doesn't appear.

Re: 3D rotation by mouse

Hi, I have to use RotationX as well. I think the mistake is in "View3DBase.cs" in method "PanOnMouseCoordinates". At the end it should be: //Check the valid range if (dRotX > m_camera.m_dRotationXMaximum) dRotX = m_camera.m_dRotationXMaximum; if (dRotX < m_camera.m_dRotationXMinimum) dRotX = m_camer...

Re: IntensityPoint in IntensityGridSeries

I had a look in the source and isn't it possible to add a PixelShader to calculate the color from the integer value instead of the Palette values? If you say "yes" I can try it on my own and write you the result. I forgot: In this case I don't need PixelRendering - it doesn't matter if it's used or ...

IntensityPoint in IntensityGridSeries

Hi, I get images from a ccd camera with a resolution of 1280x1024 pixels. The data I get is a standard RGB format. I store them as an RGB coded integer format (ARGB). For displaying the data I use IntensityPoints with IntensityGridSeries in a ViewXY. It looks good, but I only get about 2-4 images/se...

Is it possible to select an area like the zoom selection and get the informations about position and size or do I have to do it by hand?

Re: xAxis

I had a look at the CustomAxisTickXY sample. Maybe that's a good choice to work internally in pixel-size and set the axis labels "by hand".

xAxis

Hi again,
Is it possible to get an axis in curve form (polynomial)?
It's just to display an axis with an IntensityGridSeries in ViewXY.
Or is it possible to create a custom x-axis which is drawn by myself?

1. As fast as possible, with a minimum of 10 frames/second 2. two scenarios - just the pixel-position on x- and y-axis - each pixel in x-direction has it's own value on the axis. the table is calculated before (wavelength or wavenumbers) In that case the axis is not linear, it's calculated by some v...

Re: polygons with alpha

It works perfectly.
Additionally I reduced the polygons by checking the trancparency level. If it's to high it makes no sense to display it.
Now it looks nice.

So I have to add a sorting algorythm to sort the polygons depending on the distance of the camera position.

Hi, I play a little bit with LC to check if it satisfied our needs. My plan is to get a view with XYZ positions and intensity data that should be represented with different colors.
