Polar Intensity Plot - new idea??

[John Pierson]

Thats fantastic, its 90% of what i was hoping for, i would like coloured interpolation, a solid block shape over the whole area,

is that possible??

For the want of a better image, i've attatched an odd example, but its the best concept idea i could get on googleimages.

Take a look at this link for what can be drawn with the mesh datatype. I'm not sure if we would have to apply a texture or use the polygon fill. We might be able to simulate it by changing the dot size. The real trick will be figuring out whther to use triangles or quads, and the fill color between vertices.

Here are the pdf files.

Here is an option with the old 3D graph.

Hi... could you convert the file above into lv 8.2, sorry to ask again.

any luck with the change to spots?

Here is the 8.2 version. I'm not sure yet about drawing meshes instead of points. You have to send a group of vertices for each mesh region, and I haven't figured out how to group them yet.

Yatta!!

I've got what i needed working, i applied a correction to the spherical plot that i previously had. i had the problem of the dat aobscuring other parts of the data. So by applying the following corrections to each point, it 'leans' the data back so to only occupy a designated possition, 

The equations are:

Rc = sqrt(R*sin(90-theta)^2 + theta^2)

thetac = asin(theta/Rc)

Where:

Rc is the 'corrected' possition of R

R is the radius value in Spherical coordiantes

theta is the polar angle from the normal in Spherical coordinates

thetac is the 'corrected' angle for the polar plot

this gives a corection to every point that gives what i deem to be a polar intensity plot.

image attatched, i can make a vi if people would like it and its deemed useful!

Yes, please post the results. I still want to know how to take XYZ point data and turn it into a mesh surface in the 3D picture control. I'm also looking at some mathscript mesh commands.

Please do!

I'll tag it once you post it up.

Hello Ben,

I knew you were out there somewhere
