I have 2 sets of data (denoted by 250 and nothing at the end of the string)

My 2 problems:

I'm trying to make line plots through the datapoints which are the same colour as the scatter markers, how can I do this?
I want to make the colour scale for '250' and nothing data to be along different colour scales - like red and green colours of different darkness level if that is possible! Does anyone know how to do this? I've attached the code I have so far with this goal in mind

Cheers!!

powerpc=[70 58 42 28];

figure

%subplot(4,2,8);

scatter(powerpc,abs(table2array(inner70mw03))',20)

hold on

scatter(powerpc,abs(table2array(inner70mw05))',20)

hold on

scatter(powerpc,abs(table2array(inner70mw07))',20)

hold on

scatter(powerpc,abs(table2array(inner70mw09))',20)

hold on

scatter(powerpc,abs(table2array(inner70mw03_250Hz))',20)

hold on

scatter(powerpc,abs(table2array(inner70mw05_250Hz))',20)

hold on

scatter(powerpc,abs(table2array(inner70mw07_250Hz))',20)

hold on

scatter(powerpc,abs(table2array(inner70mw09_250Hz))',20)

ylabel('Carbonised region diameter/ \mum');

xlabel({'Laser Power/mW'})

M=8;

% pick some colormap and apply it to the colororder property

mycolortable = parula(M);

%set(powerpc,'ylim',[0 5])

ylim([0 25])

xlim([20 70])

set(gca,'colororder',mycolortable)

For 1. this is easy enough

Use plot instead of scatter —

powerpc=[70 58 42 28];

figure

%subplot(4,2,8);

plot(powerpc,abs(table2array(inner70mw03))', '-o')%, 'MarkerSize',20)

hold on

plot(powerpc,abs(table2array(inner70mw05))', '-o')

hold on

plot(powerpc,abs(table2array(inner70mw07))', '-o')

hold on

plot(powerpc,abs(table2array(inner70mw09))', '-o')

hold on

plot(powerpc,abs(table2array(inner70mw03_250Hz))', '-o')

hold on

plot(powerpc,abs(table2array(inner70mw05_250Hz))', '-o')

hold on

plot(powerpc,abs(table2array(inner70mw07_250Hz))', '-o')

hold on

scatter(powerpc,abs(table2array(inner70mw09_250Hz))', '-o')

ylabel('Carbonised region diameter/ \mum');

xlabel({'Laser Power/mW'})

M=8;

% pick some colormap and apply it to the colororder property

mycolortable = parula(M);

%set(powerpc,'ylim',[0 5])

ylim([0 25])

xlim([20 70])

set(gca,'colororder',mycolortable)

I do not understand what you want for 2.

As always, my pleasure!

This is the best I can do for the colours —

load('frequencywidth.mat');

cmr = colormap(hot(12));

cmg = colormap(summer(12));

powerpc=[70 58 42 28];

figure

%subplot(4,2,8);

plot(powerpc,abs(table2array(inner70mw03))', '-o', 'Color',cmr(1,:))

hold on

plot(powerpc,abs(table2array(inner70mw05))', '-o', 'Color',cmr(2,:))

hold on

plot(powerpc,abs(table2array(inner70mw07))', '-o', 'Color',cmr(3,:))

hold on

plot(powerpc,abs(table2array(inner70mw09))', '-o', 'Color',cmr(4,:))

hold on

plot(powerpc,abs(table2array(inner70mw03_250Hz))', '-o', 'Color',cmg(1,:))

hold on

plot(powerpc,abs(table2array(inner70mw05_250Hz))', '-o', 'Color',cmg(2,:))

hold on

plot(powerpc,abs(table2array(inner70mw07_250Hz))', '-o', 'Color',cmg(3,:))

hold on

plot(powerpc,abs(table2array(inner70mw09_250Hz))', '-o', 'Color',cmg(4,:))

ylabel('Carbonised region diameter/ \mum');

xlabel({'Laser Power/mW'})

% M=8;

% pick some colormap and apply it to the colororder property

% mycolortable = parula(M);

%set(powerpc,'ylim',[0 5])

ylim([0 25])

xlim([20 70])

% set(gca,'colororder',mycolortable)

Experiment with that to get the result you want, since it may be necessary to subscript into different rows of the red (‘cmr’) and green (‘cmg’) arrays to do that. Using colororder is a bit difficult here.

Thanks so much! That's exactly what I was looking for.
