Hi, Thanks for the nice sharing of the heatmap generation. I am reproducing your commands using my own datasets and found the output. In your heatmap, in the y-axis (mouse id), you did not show all labeling of mouse id [(e.g., axis.text.y = element_blank())]. would you please improve this section for how to show all samples id in y-axes . Thanks ....
