- Graph mein x-axis aur y-axis kya hote hain?
- Bar graph kab use karte hain?
- 16 se 35 kitna badha?
Answers dekho
- x = aada (jaise din), y = khada (jaise ginti)

🎬 Kahani: Chacha Ki Dukaan Ka Hafta
Rohan ke Chacha ki dukaan pe ek hafte tak gina gaya: kitne log aaye aur kitno ne khareeda.
| Din | Som | Mangal | Budh | Guru | Shukra | Shani | Ravi |
|---|---|---|---|---|---|---|---|
| Aaye | 16 | 19 | 10 | 14 | 20 | 22 | 35 |
| Khareeda | 10 | 8 | 7 | 11 | 12 | 16 | 26 |
Chacha bole, “Numbers se kuch samajh nahi aata.” Rohan ne in numbers ko bindu (dots) se lagaaya aur lines se joda… aur poori kahani ek nazar mein dikh gayi! 📈

📖 Concept: Samay Ke Saath Badlaav Dikhao
Step 1: Line graph kab?
Jab koi cheez samay ke saath badal rahi ho (din, mahina, saal), line graph sabse achha. Line ki chadhaai-utaar se badlaav turant dikhta hai.
Step 2: Banane ke kadam
- x-axis pe samay (din), barabar doori pe.
- y-axis pe ginti, ek sahi scale (jaise har line = 10).
- Har din ka bindu lagaao.
- Bindu kram se seedhi lines se jodo.
- Do data ho to alag rang aur ek legend (rang ka matlab).
Step 3: Graph padhna
- Ravivaar sabse zyada log (35) aur khareed (26).
- Budhvaar sabse kam (10 aaye, 7 khareeda).
- Mangalvaar ko log badhe (19) par khareed ghati (8)!
- Do lines ke beech ki doori = jo aaye par nahi khareeda.
WHY line? Upar-neeche jaana turant dikhta hai; table mein dhoondhna padta.
Step 4: Kai lines ek saath
NCERT ka udaharan: 2023 mein Kerala aur Punjab ka mahine-waar sabse zyada taapmaan. Punjab January (~19°C) se June (38°C) tak chadhta, phir December (~23°C) tak girta. Kerala lagbhag seedha (~29°C se ~33°C). Matlab Punjab mein taapmaan bahut badalta, Kerala mein kam.
WHY ek graph mein? Do jagahon ki tulna ek nazar mein.
Step 5: Bar graph kyun nahi?
Kai saalon aur kai deshon ka data bars mein dikhaao to 50+ bars ho jaate (NCERT: 52 bars!). Padhna mushkil. Line graph saaf.

🔐 Deep Concept: Graph Ke Beech Ka Bindu: Sach Ya Andaaza?
Line do bindu jodti hai, par beech ka hissa naapa nahi gaya. Somvaar aur Mangalvaar ke beech “aadhe din” ka koi matlab nahi! Taapmaan jaise lagataar badalne wali cheez mein beech ka andaaza theek, par dukaan ke din mein sirf bindu sach hain.
Aur graph ka scale dekho: y-axis 0 se na shuru ho to chhota badlaav bhi bada dikhta hai. Akhbaaron ke graph padhte waqt yeh chaal pakdo! 🔐

✏️ Solved Examples
Example 1 (Easy): Dukaan graph: kis din aane aur khareedne walon ka farak sabse zyada?
Farak: 6, 11, 3, 3, 8, 6, 9. Sabse zyada Mangalvaar (11).
WHY sahi hai? 19 − 8 = 11 ✅
📌 charumam.com
Example 2 (Medium): Hafte ka average aane wale log?
Jod = 136 → 136 ÷ 7 ≈ 19.4.
WHY sahi hai? 16 + 19 + 10 + 14 + 20 + 22 + 35 = 136 ✅
📌 charumam.com
Example 3 (NCERT style): Punjab ka taapmaan sabse zyada kab aur kitna?
June, 38°C. July mein 35°C se neeche gira.
WHY sahi hai? Graph ki sabse oonchi jagah ✅

🧭 Kab Use Karein, Kab Nahi
| Situation | Kya karein | Kyun |
|---|---|---|
| Samay ke saath badlaav | ✅ Line graph | Chadhaai-utaar dikhe |
| Alag cheezon ki tulna (ek samay) | ✅ Bar graph | Line ka matlab nahi |
| Hisse (poore ka bhaag) | ✅ Pie chart | Ch 3 |
| Scale 0 se nahi | ⚠️ Dhyaan se padho | Badlaav bada dikh sakta |

❌→✅ Worked Mistake
Sawaal: Graph: Somvaar 16, Mangalvaar 19. “Somvaar shaam 6 baje 17.5 log aaye.”
❌ Galat: Beech ki line ko asli data maan liya.
Galti kya hai? Data sirf poore din ka hai; beech ka bindu naapa nahi gaya ❌
✅ Sahi: Sirf diye gaye dino ki values pakki hain.
Yaad rakho: Line jodti hai, naapti nahi.
