r - Combining shape and color legends into one (ggplot) -

i'm trying combine shape , color legends 1 graph looks cleaner. example, bg data (mg/dl) filled red, cgm retropective value sensor 1 (mg/dl) filled withorange, etc.. tried working scale_color_manual , scale_shape_manual can't seem combine them.

here code:

#load libabries needed create graphs library(ggplot2) library(dplyr) library(scales) library(gridextra) library(grid)  #create dataset subject data1<-subset(carb_data,subject.id.. == 1)  carb1<-subset(data1,visit == 1)  #makes sure "amount" stored number , "time" stored date carb1$amount = as.numeric(as.character(carb1$amount)) carb1$time = as.posixct(carb1$start, format = "%h:%m", tz = "gmt")  q <- ggplot(data=carb1, aes(x=time, y=amount, group=type, color= type, shape=type, label=amount)) +     geom_point(data=carb1[carb1$type=="bg data (mg/dl)", ], size=2, colour="red") +    geom_point(data=carb1[carb1$type == "cgm retropective value sensor 1 (mg/dl)", ], size=4) +    geom_point(data=carb1[carb1$type == "cgm retropective value sensor 2 (mg/dl)", ], size=4) +    geom_point(data=carb1[carb1$type == "cgm retropective value sensor 3 (mg/dl)", ], size=4) +     geom_point(data=carb1[carb1$type == "cgm retropective value sensor 4 (mg/dl)", ], size=4) +    theme(text = element_text(size=10),           axis.text.x = element_text(angle=90, vjust=1)) +     scale_y_continuous(breaks = round(seq(0, max(carb1$amount), = 50),2)) +     xlab("time (hh:mm)") + ylab("glucose (mg/dl), carbohydrates (grams)") +     ggtitle(tostring(c("cgm retrospectve , reference values"))) +     geom_bar(data=carb1[carb1$type=="disconnect or reconnect time", ], width=.1, stat="identity") +   scale_x_datetime(breaks=date_breaks("1 hour"), labels= date_format("%h:%m")) +    theme_bw() +   scale_shape_manual(values=c(16,1,2,3,5,6))   print(q) 

and data:
