Simplification and circles pointing to axis help of multiple coloured yaxis pgfplot

Question

I have generated the below plot how I want.

Can this be simplified?

However I found it very convoluted to colour the y axis, labels and tick labels, whilst keeping the x axis black. Setting the colour style of the axis seems particularly bad.

y axis line style = {mycolor2},
y axis line style = {mycolor2},
y tick label style= {mycolor2},
y tick style= {mycolor2},
ylabel style = {mycolor2},

Is there a simpler way that I can do this?

How to do circles around lines

I would also like to put circles around each line pointing to the axis which it is linked to. How is best to do that?

Can I draw figure 3 y axis using pgfplot?

Change legend color in multiple y-axis plot in pgfplots

pgfplots: two y-axis with three plots and one legend

Answer 1

You could define a style for that,

\pgfplotsset{yaxis stuff style/.style={y axis line style = {#1},
y tick label style= {#1},
y tick style= {#1},
ylabel style = {#1},
}}

and use it in the two axes.

\pgfplotsset{compat=1.16}
\pgfplotsset{yaxis stuff style/.style={y axis line style = {#1},
y tick label style= {#1},
y tick style= {#1},
ylabel style = {#1},
}}

In principle you could only add \color{mycolor1} and \color{mycolor2} before the respective axis.

However, I do not recommend that.
