Custom x-axis label in quantmod chartSeries

Dear Ilya,

Thanks for the prompt reply!  The code from my previous message works and
I uploaded as an example so you could see what my intent is.  Your
suggestion will be considered, thank you! Its output is attached (which is
in Portuguese).

Thanks,

This isn't a reproducible example--we don't have the stocks data frame.
Also, it is bad practice to use dplyr in the R/Finance stack as it
overrides multiple functions, such as lag and filter.

Hello,

Is it possible to customize the x-axis label? Using ggplot I have the
custom x-label described below,

stocks %>%
ggplot(aes(x = date, y = cum_ret)) +
    theme_gray() +
    theme(plot.background = element_rect(fill = "gray86")) +
    geom_line(color = "blue") +
    *theme(axis.text.x = element_text(angle = 50, hjust = 1))* +
    labs(x = 'Data',
         y = 'Cumulative Return',
         title = paste0('Portfolio Cumulative Return of ',
length(tickers.clean), ' stocks on ',
                        format(as.Date(end), format="%d/%m/%Y")),
         subtitle = paste0("Ativos: ", toString(tickers.clean),
"\nWeights:
",
                           toString(percent(wts, accuracy = 0.1)))
         ) +




* scale_x_date(date_breaks = '2 weeks',
date_labels = '%d %b %y') +    scale_y_continuous(        breaks = seq(0,
10, 0.05),        labels = scales::percent_format(accuracy = 1)*
    )

TIA,
