# How to Create a Bone of Cylinder with Ellipse with Python?

Hi all,

it’s been long, I have been using Julia for so long almost 1 year, thus I want to try can Python plot better than Julia?

I want to plot the right side of this picture

I have plot the left side with Julia:

using Plots, LaTeXStrings, Plots.PlotMeasures
gr()

f(x) = sqrt(x)

plot(f,0,4, xtick=0:4:4, xlims=(0,6), ylims=(0,3),
framestyle=:zerolines, bottom_margin=5mm,
label=L"y = \sqrt{x}", legend=:topright)

plot!(f,0,5, label="", fill=(0, 0.15, :blue))
plot!(f,2,2.3, label="", fill=(0, 0.35, :blue))

# Annotations
annotate!([(2.12,1.6, (L"△ x", 8, :blue))])
annotate!([(2,-0.1, (L"x_{i}", 8, :blue))])
annotate!([(2.4,-0.1, (L"x_{i+1}", 8, :blue))])


Is Python able to plot the right side? since it seems complex to do so in Julia. Thanks before.

I don’t see any obvious reason why you couldn’t plot that using Python. What have you tried so far? I would recommend looking into a package like matplotlib, which can handle some pretty complicated plots.
