I have generated following heatmap
Is it possible to make cells with zero entries just to display the colour without the value?
rawdata = readmatrix('Wave data_Galle_NARA.xlsx');
Hs_edges = 0.5:0.5:4.5;
Tp_edges = 5:1:22;
[N,Xedges,Yedges,binX,binY] = histcounts2(rawdata(:,2),rawdata(:,1),Tp_edges,Hs_edges,'Normalization','probability');
h = heatmap(N')
Thank you!

Ran in:
i don't think it's possible. But what about using the missing property
clear;
close all;
rawdata = readmatrix('Wave data_Galle_NARA.xlsx');
Hs_edges = 0.5:0.5:4.5;
Tp_edges = 5:1:22;
[N,Xedges,Yedges,binX,binY] = histcounts2(rawdata(:,2),rawdata(:,1),Tp_edges,Hs_edges,'Normalization','probability');
N(N==0) = nan;
h = heatmap(N(1:5,1:5)',MissingDataLabel='no data',MissingDataColor=[1 0.9 0.9]);
