Is it possible to increase the number of ticks shown on the axes of a qic chart?

Question

This is the code for my chart, I want to increase the number of ticks in the X Axis

qic(x       = as.Date(SubStrDate, '%d-%m-%Y'),
y           = DNARate, # add fields here
data        = dataset,
chart       = 'i', #chart type
facet       = ~ TumourType,
title       = "SPC Analysis of AVG Days Booked to First Seen",
ylab        = 'Count',
xlab        = 'Date',
x.format    = '%d-%m-%Y',
x.angle     = 90,
x.pad       = 0,
show.grid   = TRUE

I tried various things; nint, breaks
