I need to create a scatter table representing the proportional frequency of different sea states. For this I have 3 arrays (Hs_10yr, Te_10yr and Dir_10 yr). I nedd a scatter table with bins using the parameters Hs and Te but for different directional bins (windows). I already have the script for scatter table but I don't know how to set the condition for example to get a table for Dir = 180: 270 degree.How can I obtain this?
hFig = figure;
hAxes = axes(hFig);
xVals = Te_10yr;
yVals = Hs_10yr;
xEdges = 1:0.5:12.5;
yEdges = 0:0.5:4.5;
%yEdges = min(yVals):0.5:max(yVals);
hist_Counts = histcounts2(xVals,yVals,xEdges,yEdges);
hist_Counts_normalized = (hist_Counts / sum(hist_Counts,'all'))*100;
hHist = histogram2(hAxes,'XBinEdges',xEdges,'YBinEdges',yEdges,'DisplayStyle','tile','BinCounts',hist_Counts_normalized);
colormap(colorMap_occ);
colorbar;
xBinCenters = hHist.XBinEdges - [0,diff(hHist.XBinEdges)/2];
yBinCenters = hHist.YBinEdges - [0,diff(hHist.YBinEdges)/2];
for i = 2:numel(xBinCenters)
for j = 2:numel(yBinCenters)
x_loc = xBinCenters(i);
y_loc = yBinCenters(j);
if ~(round(hHist.Values(i-1,j-1),4) == 0)
text(hAxes,x_loc,y_loc,[num2str(round(hHist.Values(i-1,j-1),3),'%4.3f'),'%'],'Color',[0 0 0],'FontSize',9,'FontWeight','bold','HorizontalAlignment', 'center');
else
continue
end
end
end
box(hAxes,'on');
grid(hAxes,'on');
axis(hAxes,'tight');
hold(hAxes,'off');

What do you mean when you use the term "different directional bins (windows)"? Do you mean you want to have bins along x and y that are different widths? That's not going to be hard to do.
Do you have a picture of what you're hoping to receive as the end result? It kind of looks from your text calls like you want a heatmap but I'm not 100% sure.

Yes it is a heatmap. To be more exactly I want to filter data that apears in heatmap (Hs and Te) depending the Dir variable. I don't need Dir to appear in my heatmap. It is used only to filter data (Hs and Te). So the variable Dir is between 0 and 360 and I need to get data of Hs and Te only for Dir between 90 and 180.
