How to fix axes in heatmap plot? The heatmaps are presented as a movie.

I have a movie builded with heatmaps. When each heatmap is displayed, the axes are changing and I need the axes fixed.

The code that I am using is the following

% Declear all;
clc;
syms x y z S
var = {'GeneX','GeneY','GeneZ'};

Jnovo=[1,y^3,2*x;0,y^3,2*x;x^2,y^3,2*x]; 
Jsolnew(x,y,z,S) = [Jnovo]

A=rand(4,300);% import data from directory
a2=A;% coordinates of the equilibrium point.
numofGraphs=30;
bx=length(a2(1,1:numofGraphs));

workspace;
numberOfFrames = numofGraphs;
t = linspace(0, 5, numberOfFrames);
hFigure = figure;


vidHeight = 344;
vidWidth = 446;

allTheColorMaps = cell(numberOfFrames,1);
allTheColorMaps(:) = {zeros(256, 3)};
set(gcf, 'renderer', 'zbuffer');

for frameIndex = 1 : numberOfFrames
  
    JacACDCnew(:,:,frameIndex) = Jsolnew(a2(1,frameIndex),a2(2,frameIndex),a2(3,frameIndex),a2(4,frameIndex));
	ACDC_HmapJnew = double(JacACDCnew(:,:,frameIndex));
    heatmap(var,var,ACDC_HmapJnew,'ColorScaling','log');
	caption = sprintf('Frame #%d of %d, t = %.1f', frameIndex, numberOfFrames, t(frameIndex));
	title(['Jac','s=',num2str(frameIndex)]);
	drawnow;% allow to see the graph inmediately
	
end
% close(writerObj);

But in this moment, I have a problem with the color, for example the value 1 is changing the color, but this is wrong because the value 1 is always constant, and the color is changing when the next heatmap is plotted

I hope to find a way to fix the axes and see the evolution of the colors.
