Doiraviy diagrammalar

Doiraviy diagramma — ma’lumotlarning aylana shaklidagi grafik ko‘rinishi.

Doiraviy diagrammalar chizish uchun pie() funksiyasidan foydalaning:

Misol

# Create a vector of pies x <- c(10,20,30,40) # Display the pie chart pie(x)

Natija:

O‘zingiz sinab ko‘ring »

Misol tushuntirilishi

Ko‘rib turganingizdek, doiraviy diagramma vektordagi har bir qiymat uchun bittadan bo‘lak chizadi (bu holda 10, 20, 30, 40).

Standart holatda birinchi bo‘lakni chizish x o‘qidan boshlanadi va soat miliga teskari yo‘nalishda davom etadi.

Boshlang‘ich burchak

init.angle parametri yordamida doiraviy diagrammaning boshlang‘ich burchagini o‘zgartirishingiz mumkin.

init.angle qiymati burchak sifatida gradusda beriladi, standart burchak esa 0 ga teng.

Misol

Birinchi bo‘lakni 90 gradusdan boshlang:

# Create a vector of pies x <- c(10,20,30,40) # Display the pie chart and start the first pie at 90 degrees pie(x, init.angle = 90)

Natija:

O‘zingiz sinab ko‘ring »

Yorliqlar va sarlavha

Doiraviy diagrammaga yorliq qo‘shish uchun label parametridan, sarlavha qo‘shish uchun esa main parametridan foydalaning:

Misol

# Create a vector of pies x <- c(10,20,30,40) # Create a vector of labels mylabel <- c("Apples", "Bananas", "Cherries", "Dates") # Display the pie chart with labels pie(x, label = mylabel, main = "Fruits")

Natija:

O‘zingiz sinab ko‘ring »

Ranglar

col parametri yordamida har bir bo‘lakka rang berishingiz mumkin:

Misol

# Create a vector of colors colors <- c("blue", "yellow", "green", "black") # Display the pie chart with colors pie(x, label = mylabel, main = "Fruits", col = colors)

Natija:

O‘zingiz sinab ko‘ring »

Legenda

Har bir bo‘lak uchun izohlar ro‘yxatini qo‘shish uchun legend() funksiyasidan foydalaning:

Misol

# Create a vector of labels mylabel <- c("Apples", "Bananas", "Cherries", "Dates") # Create a vector of colors colors <- c("blue", "yellow", "green", "black") # Display the pie chart with colors pie(x, label = mylabel, main = "Pie Chart", col = colors) # Display the explanation box legend("bottomright", mylabel, fill = colors)

Natija:

O‘zingiz sinab ko‘ring »

Legendani quyidagi joylardan biriga joylashtirish mumkin:

bottomright, bottom, bottomleft, left, topleft, top, topright, right, center
