Hi,

I want to draw a huge amount of lines in a graph (many hundreds).
Each line property can be accessed in vectors (position, color, name).
I've been using LT but was wondering if I could speed things up with OC.

So far, only way I found was to loop through my vectors and use CreateGraphObject, set up a tree style, UpdateThemeIDs and ApplyFormat.

In the end, time execution is about the same. Looks like UpdateThemeIDs and ApplyFormat are highly time consumming.
Is there any way to massively create, set and apply style in one shot (maybe with Collection<GraphObject> grobjcollection) ?

Interesting.

Played a bit with the options but looks like all the objects are joined together, so no possibility to edit/delete them separately afterwards.

Thanks anyway

    gp.Create();

    gl = gp.Layers();

    gl.CreateShapeGraphObjects(vxPos, vyPos, vShapeIndex, vBlockIndex, "lines", 0, CPO_POLYLINE);
}
