heatmap column(sample) names disordered

Hi dear biostar community,

I have a problem with my heatmap output. I want to draw a heatmap of 45 topvar genes for 52 samples.
but my column (sample) names are shown disordered. (e.g. f1d#num is femal-1dpi-disease, and f1c#num is female-1dpi-control)
as you can see, column have not any meaningful order.
what can I do?

many thanks
