Jab data bahut ho, chitra banane mein bahut samay lagta hai. Bar graph iski jagah bars use karta hai. Yahan: ek hafte har din kitne bachche der se aaye. Budhvaar ko sabse zyada; Shanivaar ko koi der se nahi aaya.

Bars ki chaudai same aur gap barabar hote hain. Bade numbers ke liye hum scale use karte hain. Yahan school science fair mein 1 unit length = 100 visitors. Sabse ooncha bar, 11–12, 1,100 visitors dikhaata hai.

Hum jod aur milaan bhi kar sakte hain. 10 se 12: 900 + 1,100 = 2,000 visitors. 9 se 10 itne kam kyon? Bahut se parivaar abhi pahunche nahi the!

900 + 1,100 = 2,000

Explore: science fair ka bar graph banao. Har bar ko sahi oonchaai tak kheencho.

1. Bars lagao: 9–10 250, 10–11 900, 11–12 1,100, 12–1 700.
2. Kis ghante mein doosre sabse zyada visitors the? Use tap karo.
