How do I change the properties of a series od data in a plot with multiple series of data in it ?

I have 3 series of datain the same plot, and I would like to change properties such as color and marker type on each different data series from command line, i.e without the property editor.

I attached a matlab figure to be more clear, for example how do I cange the marker type of the different data series ?

Open the figure

f =openfig('W_1e-6_5e-9.fig');

access its axis either by gca or by figure handle f

axes = gca;

Axes has three lines i.e. 3 childrens

axes.Children
ans = 

  3×1 Line array:

  Line    ( W = 250 nm)
  Line    ( W = 500 nm)
  Line    ( W = 1e-6 m)

To access 1st line color (and other properties)

  axes.Children(1).Color
  ans =

    0.9290    0.6940    0.1250

to change marker type and color of plot

    axes.Children(1).Marker = 'diamond';
    axes.Children(1).Color = 'm';
