I have the following code that is supposed to show a multi-line graph with both lines and markers:
import(plotly)
df = data.frame(DATE = c('2022-09-01','2022-09-02','2022-09-03','2022-09-04', '2022-09-01','2022-09-02','2022-09-03','2022-09-04'),
SIZE = c(200,200,180, 110, 20, 15, 15, 10),
PRICE = c(99, 95.5, 96, 96, 80, 79, 77, 77),
ID = c('ABC','ABC','ABC','ABC','DEF','DEF','DEF','DEF'), stringsAsFactors = F)
df$DATE = as.Date(df$DATE)
plt <- df %>% plot_ly( x = ~eval(parse(text='DATE')),
y = ~eval(parse(text='PRICE')),
color = ~eval(parse(text='ID')),
name = ~eval(parse(text='ID')),
connectgaps = TRUE) %>% add_lines() %>% add_markers()
It works ok but my goal is to have each marker size defined through column "SIZE". Is there any way to accomplish this? I couldn't find a similar question. Thanks
CodePudding user response:
Adding size = ~SIZE,
seems to work well.
Is it what you were searching for?
df %>% plot_ly( x = ~eval(parse(text='DATE')),
y = ~eval(parse(text='PRICE')),
size = ~SIZE,
color = ~eval(parse(text='ID')),
name = ~eval(parse(text='ID')),
connectgaps = TRUE) %>% add_lines()
