The x-axis chromosome ID is missing in the result of pafCoordsDotPlotly.R.

[lvqiang0120]

Hi,
I have 11 chromosomes in both my reference and query sequences. However, after using Minimap2 to generate a PAF file and then using pafCoordsDotPlotly.R to plot it, the y-axis displays 11 chromosome IDs while the x-axis only displays 9 chromosome IDs. I am sure that my reference sequence contains all 11 chromosomes. I do not know why two chromosome ID numbers are missing on the x-axis.

There are my command line：
/minimap2 -x asm5 $ref $query -t $thread > $out_dir/"$prefix".minimap2.paf
pafCoordsDotPlotly.R -i "$prefix".minimap2.paf -o "$prefix".drplot -k 11 -q 10000 -m 200000 -r chr1,chr2,chr3,chr4,chr5,chr6,chr7,chr8,chr9,chr10,chr11 -x

Log file prompt：
