h = heatmap({'A', 'B', 'C' , 'D', 'E', 'F', 'G', 'H'}, feature_names, data');
h.XLabel = 'Project';
h.YLabel = 'Metric';
h.CellLabelFormat = '%.2f';

Ytick is not perfectly aligned with yticklabel in the vertical direction. The yticklabel has a slight downward shift.

Could anyone tell me how to solve it? i have not found any settings about yticklabel alignment

Hi Yihang,

I understand that you are facing issue with Ytick not being aligned with YtickLabel.

Please note that the 'yvar' in the heatmap chart are aligned along the centre of the rows. This is in accordance with the various examples in heatmap documentation.

Hope this helps!!

When number of 'yvar' increases, 'yvar' will gradually shift downwards, causing YTickLabel not aligned with rows. The picture in heatmap documentation below also reveal the problem. 'fire' and 'wind' obviously are not aligned with the center of rows. When number of 'yvar' is large enough, the misalignment will be prominent, just like the first picture in my question.
