I want to generate Heatmap for irregular Time series data

Dear all

I am new for matlab. I tried to plot a heat map for a dataset but it doesnt work and sample graph format is also attached for reference which i need to plot and i attached a sample data. I had tried using the below following codes. So kindly help me to resolve this issus. Thank you in advance.

x = dta(:,1); 
y = dat(:,83);
z = dat(:,2:82); 
tbl = table(x,y,z); 
h = HeatMap(tbl,'x','y','ColorVariable','z','ColorMethod');
Error using HeatMap
Expected DATA to be one of these types:

numeric, bioma.data.DataMatrix

Instead its type was table.

Error in bioma.util.validateMatrix (line 10)
validateattributes(data, {'numeric', 'bioma.data.DataMatrix'},...

Error in HeatMap/setDisplayDataOnly (line 784)
            bioma.util.validateMatrix(data, 'DATA', 'HeatMap')

Error in HeatMap/setDisplayData (line 779)
            obj = setDisplayDataOnly(obj, data);

Error in HeatMap/set.Data (line 523)
            setDisplayData(obj, data)

Error in HeatMap (line 366)
            obj.Data = data;

T = readtable('dat.csv') ;
x = T.(1) ; 
x(1) = [] ;

x = datetime(datestr(x)) ; 
y = table2array(T(1,2:end)) ;
data = table2array(T(2:end,2:end)) ;
pcolor(x,y,data')
shading interp 
colorbar

Thank you for your idea KSSV i will try this and let you know if i get any error i will contact you agin

Hai KSSV

i got the error message from third line itself.

x=datetime(datestr(t));

Undefined function or variable 't'.

After i got the error i changed captial T but again it shows error

x=datetime(datestr(T));

Error using datestr (line 177)

Cannot convert input into specified date string.

DATENUN failed.

help me to fix this error KSSV

Variable t is x... Typo error.. Edited the answer.

I changed it and it is going good till pcolor(x,y,data') Error using pcolor (line 63) Data inputs must be real. This above error is pop up. Next what I have to do KSSV.
