plot.dist.py output to screen only 
I've calculated mosdepth coverage with the command: 

mosdepth -n -b 500 -x -t 4 -Q30 $OUTPUT_DIR/${base%.cov} ${this_bam}

I run plot-dist.py with: 

python mosdepth-0.3.3/scripts/plot-dist.py *.global.dist.txt

However, the output prints to screen and an empty html is created. Is there something I'm doing wrong? Output file attached. TIA.
