Mutiple colorbars for mutiple scatter plots in the same figure

I want to make two pairs of scatter plots, for a total of four. Where each pair will be shown by a different color bar. I looked for help on the Internet, but I couldn't find the best way to get the results I need. The other pair of plots is not shown in my figure.That means there should one more pair of scatter plots whoch are symmetric to the plots shown and will represent the second colorbar. Below is my code

x1 = rand(1,150); x2 = rand(1,100); y1 = x1.^2; y2 = x2.^(1/2);

x3 = rand(1,150); x4 = rand(1,100); y3 = -x3.^2; y4 = -x4.^(1/2);

Conc = [y1 y2]; Conc2 = [y3 y4];

figure

ax1 = axes;

scatter([x1, x2],[y1, y2],40,Conc,'filled');

axis equal

hold on

ax2 = axes;

scatter([x3, x4],[y3, y4],40,Conc2,'filled');

axis equal

hLink = linkprop([ax1,ax2],{'XLim','YLim','CameraUpVector','CameraPosition','CameraTarget'});

ax2.Visible = 'off';

ax2.XTick = []; ax2.YTick = [];

colormap(ax1)

colormap(ax2,'spring')

cb1 = colorbar(ax1,'Position',[0.1 0.1 0.05 0.815]);

cb2 = colorbar(ax2,'Position',[0.81 0.1 0.05 0.815]);

cb1.Label.String = 'Colorba1'; cb2.Label.String = 'Coloebar2';

cb1.Label.FontSize = 28; cb2.Label.FontSize = 28;

It will be a great help if anyone can put me in the right direction

Have a look at the file exchange contribution newcolorbar-multiple-colormaps-in-the-same-axes. It seems as it should let you do this.

Thanks! for your help.

My orignal plots are as you can see below is a result of four scatter plots. Where each pair of the petal shaped plots belong to one colorbar. That means I have four scatter plots, but I need two colorbars. I can generate the plots by

x1 = rand(1,150); x2 = rand(1,100); y1 = x1.^2; y2 = x2.^(1/2);

Conc = [y1 y2];

x3 = rand(1,150); x4 = rand(1,100); y3 = -x3.^2; y4 = -x4.^(1/2);

Conc2 = [y3 y4];

figure(1)

scatter([x1, x2],[y1, y2],40,Conc,'filled');

hold on

scatter([x3, x4],[y3, y4],40,Conc2,'filled');

Which will give me the following plot

As per you suggested I tired the follwing

x1 = rand(1,150); x2 = rand(1,100); y1 = x1.^2; y2 = x2.^(1/2);

Conc = [y1 y2];

x3 = rand(1,150); x4 = rand(1,100); y3 = -x3.^2; y4 = -x4.^(1/2);

Conc2 = [y3 y4];

figure(1)

scatter([x1, x2],[y1, y2],40,Conc,'filled');

colormap('parula')

colorbar('WestOutside')

hold on

cb2 = newcolorbar('EastOutside','color','blue');

scatter([x3, x4],[y3, y4],40,Conc2,'filled');

colormap(gca,'spring')

But I still have the same problem as before. That is I can not get the other pair of plots that belong to the colorbar on the east side. Please let me know if there is anyway to fix this.
