Risk Matrix in MATlab

Dear altruist,

I want to create a risk matrix like the attached image. My code is ( I get simmilar types of code from here:How can I create a Risk Matrix Plot? - (mathworks.com)) :

%Define risk matrix 1-3 (1 low - 2 medium - 3 severe)

C=[2 3 3 3 3 3;

2 2 3 3 3 3;

1 2 2 3 3 3;

1 1 2 2 3 3;

0 1 1 2 3 3;

0 0 1 1 2 3];

%Values for each cell

V=[1:5; 6:10; 11:15; 16:20; 21:25]

ax=axes

hold on

%Draw colored grid

[X,Y]=meshgrid(1:size(C,1),1:size(C,2))

h=imagesc(X(:),Y(:),flipud(C))

%Define colors (green, yellow, red)

cmap=[0 1 0;1 1 0;1 0 0];

% Add cell values

str = sprintfc('%d',V(:))

text(X(:),Y(:),str)

% Define row and column labels

RowLabels={'Very unlikely < Once in 100 Years','Unlikely, once in 10 years',

'Uncommon, Once a year', 'Infrequent, once a month', 'Frequent, once a week',

'Very frequent >once a day'};

ColLabels={'Negligible or harmless injury','Injury without reporting sick',

'Recoverable injury, reporting sick <14d', 'Recoverable injury, reporting sick >14d',

'Disability/Death', 'Several deaths/Large hazardous area'};

% Some axes settings

set(gca,'xtick',unique(X),...

'ytick',unique(Y),...

'yticklabels',RowLabels,...

'xticklabels',ColLabels)

% Add colorbar and describe colors

cb=colorbar(ax,'location','southoutside')

set(cb,'ticks',[1.3 2 2.7],...

'ticklabels',{'Low risk','Medium risk','High risk'},...

'ticklength',0)

box on

set(ax,'layer','top')

colormap(cmap)

Could you please tell me, how can I update my code to get this?

This is getting pretty close:

%Define risk matrix 1-3 (1 low - 2 medium - 3 severe)

C=[2 3 3 3 3 3;

2 2 3 3 3 3;

1 2 2 3 3 3;

1 1 2 2 3 3;

0 1 1 2 3 3;

0 0 1 1 2 3];

%Values for each cell

V=1:36;

ax=axes

hold on

%Draw colored grid

[X,Y]=meshgrid(1:size(C,1),1:size(C,2))

h=imagesc(X(:),Y(:),flipud(C))

%Define colors (green, yellow, red)

cmap=[0 1 0;1 1 0;1 0 0];

% Add cell values

str = sprintfc('%d',V(:))

text(X(:),Y(:),str)

% Define row and column labels

RowLabels={"Very unlikely < Once in 100 Years","Unlikely, once in 10 years", ...

"Uncommon, Once a year", "Infrequent, once a month", "Frequent, once a week", ...

"Very frequent >once a day"};

ColLabels={"Negligible or harmless injury","Injury without reporting sick", ...

"Recoverable injury, reporting sick <14d", "Recoverable injury, reporting sick >14d", ...

"Disability/Death", "Several deaths/Large hazardous area"};

% Some axes settings

set(gca,'xtick',unique(X),...

'ytick',unique(Y),...

'yticklabels',RowLabels,...

'xticklabels',ColLabels,...

'XTickLabelRotation', 90,...

'XAxisLocation','top')

% Add colorbar and describe colors

cb=colorbar(ax,'location','southoutside')

set(cb,'ticks',[1.3 2 2.7],...

'ticklabels',{'Low risk','Medium risk','High risk'},...

'ticklength',0)

box on

set(ax,'layer','top')

colormap(cmap)

@Benjamin Thompson,thanks a lot :D

But how can I add 0, 1, 2 3,.... , move low risk to the middle and C matrix was different value
