adding two colorbars in the uiaxes of app designer matlab

I would like to achieve this in app designer (withing UIAxes). The following is my attempt(following https://www.mathworks.com/matlabcentral/answers/194554-how-can-i-use-and-display-two-different-colormaps-on-the-same-figure):

function ButtonPushed(app, event)

x=randn(1000,1);
y=randn(1000,1);
ax1 = app.UIAxes;
histogram2(ax1,x,y,linspace(-3,3,30),linspace(-3,3,30),'DisplayStyle','tile')
 
hold (ax1,"on")
ax2 = app.UIAxes;
 scatter(ax2,x,y,10,x.^2 + y.^2, 'filled')
hold (ax2,"off")
 
 linkprop([ax1,ax2],'CLim');

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

 colormap(ax1,'hot')
colormap(ax2,'spring')

 cb1 = colorbar(ax1, "westoutside");  
cb2 = colorbar(ax2, "eastoutside");
cb1.Label.String = 'histogram';
cb2.Label.String = 'scatter';
cb1.Label.FontSize = 12;
cb2.Label.FontSize = 12;

 
end

However, it seems like not giving the correct colorbars. I attheched the output below. Your help will be appreciated.

Note that ax1 and ax2 are the same axes:

ax1 = app.UIAxes;
% ...
ax2 = app.UIAxes;

You won't be able to have multiple colormaps in one axes, but you can make a second axes, invisible and overlaying the first.

Something like this would work:

x=randn(1000,1);
y=randn(1000,1);

f = uifigure('Position',[50 50 1000 500]);
ax1 = uiaxes(f,'Units','normalized','Position',[0.15 0.1 0.7 0.8],'Box','on');
ax2 = uiaxes(f,'Units','normalized','Position',[0.15 0.1 0.7 0.8],'Visible','off');

histogram2(ax1,x,y,linspace(-3,3,30),linspace(-3,3,30),'DisplayStyle','tile')

scatter(ax2,x,y,10,x.^2 + y.^2, 'filled')

linkprop([ax1,ax2],{'CLim','XLim','YLim','Position'});

ax1.XTick = [];
ax1.YTick = [];

colormap(ax1,'hot')
colormap(ax2,'spring')

cb1 = colorbar(ax1, "westoutside");
cb2 = colorbar(ax2, "eastoutside");
cb1.Label.String = 'histogram';
cb2.Label.String = 'scatter';
cb1.Label.FontSize = 12;
cb2.Label.FontSize = 12;

This is moving the plots to a new figure window. I want to have plots in the existing apps UIAxes. I have attached my apps code.

Try the modified version attached.

Thanks. That's working. Only issues I noticed so far is that sometime plots moving outside the box as like below:
