When I set tick_length=10, this parameter does not take effect, but it works when tick_length=2.

When I set tick_length=10, this parameter does not take effect. When tick_length=2, it takes effect. The length of the line does not change when the number is greater than 5，Thankyou!

if sector.name in genechr:
gene_data = genenames[genenames["query_chr"] == sector.name]
label_pos_list = gene_data["query_start"].tolist()
labels = gene_data["genename"].tolist()
outer_track.xticks(
label_pos_list,
labels,
label_orientation="vertical",
label_size=6,
tick_length=10,
line_kws=dict(ec="black"),
)
