hello
i have an image from a face, i ploted this image using (Filled area 2-D plot),
i attached my result, i wanna find maximum Y from plot(as you see in this image is Y=11)
I coudnt use ''findpeaks'' because my output type from this kind of plot(Area) is 1*92 Area

You can use findpeaks, available in Signal Processing Toolbox to find local maxima.

If data is available to you then you may try this code.
[max_col, rows] = max(data)
[peak, col_idx] = max(max_col) %peak -> peak value in data, col_idx -> column index of peak value
row_idx = rows(col_idx) %col_idx -> row index of peak value
Stacked value can be calculated by summing up the row containing peak value
