Learning Plots... now: marker_z?

[JackDevine]

It is weird that GR and PyPlot give different answers here…

That said, I am not precisely sure of what you expected to happen. If you just use

plot(xm,ym,seriestype=:scatter,markershape=:circle,linecolor=false,marker_z=1:100)

then you will find that the code will work the same on both backends. The difference here is that I added seriestype=:scatter. So the moral of the story is that scatter and plot do different things.

From the documentation:

line_z and marker_z parameters will map data values into a ColorGradient value

I hope that this helps.

PS: Have a look at this post on backticks

PSA: how to quote code with backticks

This is a short post on using backticks (` and ```) to quote code, with the intention of benefiting users who are confused by this feature of the site. The intention is to make it linkable when necessary. Why By quoting your code, you get a monospaced font (which preserves indentation) and syntax highlighting. This helps people who read your code and want to help you. Displayed code looks like this: function displayed_code(x::Int, y::Int) if x < y println("x is smaller") else …

It allows you to get your code looking beautiful on discourse. It might help if you try asking a more complex question.
