Plots: bring forward, send backward

How do I ...? with Maple

Hello,

I need to plot a solid circle on a line. The problem is that you can see the line through the circle:

with(plots):
with(plottools): 
l := plot(x,color=red,thickness=3): 
d:=disk([0.5, 0.5],0.05,color=black): 
display({l, d},view=[0..1,0..1]);

I think I need something which is called in Microsoft Office products "Bring Forward (or to Front)" and "Send Backward (to Back)"

I suppose it's something very simple but I just cannot find it!

Thank you!

I'm afraid not

I'm afraid that function isn't currently available in Maple.

For this particular situation, if the only need is to get a large dot on a line, one could do something like:

l := plot(x, color = red, thickness = 3);
d := pointplot([.5, .5], symbol = solidcircle, symbolsize = 70);
display([l, d], view = [0 .. 1, 0 .. 1]);

You could also transform the dot and line to 3d objects where the dot is a little bit above the (x,y) plane where the line is situated, and project down:

with(plots):
with(plottools):

l := plot(x,color=red,thickness=3):
d:=disk([0.5, 0.5],0.05,color=black):

l3d:=transform((x,y)->[x,y,0])(l):
d3d:=transform((x,y)->[x,y,0.1])(d):

display(l3d,d3d,axes=boxed,view=[0..1,0..1,0..0.2],orientation=[-90,0]);

Thank you!

Thank you, Tim and Alex!

This is kind of tricks I was trying to get (though I would never think of transforming it in 3d!)
