Hello,
I'd like to customize the makeChart function output of the quantmod
library. Its main objective is threefold:
1. have x axis labels at 45 degree angle.
2. have a title and subtitle
3. have labels legends.
I can obtain the desired output via the ggplot code below. However, the
chartSeries() function doesn't work. port_cumulative_ret along with the
other data required are obtained via tiidyquant library.
port_cumulative_ret %>%
## axis data
ggplot(aes(x = date, y = cum_ret)) +
## plot configuration
theme_gray() +
theme(plot.background = element_rect(fill = "gray86")) +
geom_line(color = "blue") +
theme(axis.text.x = element_text(angle = 50, hjust = 1)) + ## x axis
text at 45 degree angle
## graph text, notation and number settings
labs(x = 'Data',
y = 'Cum Return',
title = paste0('Portfolio Cum Return on ', format(as.Date(end),
format="%m/%d/%Y")),
subtitle = paste0("Actives: ", toString(tickers.clean),
"\nWeights: ",
toString(percent(wts, accuracy = 0.01)))
) +
## axis numbering settings
scale_x_date(date_breaks = '2 weeks',
date_labels = '%d %b %y')
)
Thanks in advance for any help.
