Hello,

I want to plot a network using tubes and glyphs.  I generated the test file

object 1 class array type float rank 1 shape 2 items 3 data follows
0.0     0.0
0.5     0.0
1.0     0.0
object 3 class array type int rank 1 shape 2 items 2 data follows
0 1
1 2
attribute "element type" string "lines"
attribute "ref" string "positions"
object "line-part" class field
component "positions" value 1
component "connections" value 3
end

and tried:

dx -script

data = ""
connections = ShowConnections(data);
positions = ShowPositions(data);
glyphs = AutoGlyph(positions);
tubes = Tube(connections, 0.02);
all = Collect(tubes,glyphs);
camera = AutoCamera(all);
image = Render(all, camera);
Display (image);

This more or less works, but it seems that the size of the glyphs can only
be determined by data, while I would like to change it independent of data.
Is that possible?

Thank you, Nicolas.

Use Glyph, instead of Autoglyph and set the ratio between
the smallest and largest glyph to 1.0. This creates uniformed

size glyphs. The size itself is then determined by the scale

parameter of glyph.
