Simple Bar Diagram Task

1. From the following data relating to cement production of a factory (2018-2023), prepare a simple bar diagram.

\begin{tabular}{|c|c|c|c|c|c|c|}
\hline
Year & 2018 & 2019 & 2020 & 2021 & 2022 & 2023 \\
\hline
Production (in M. Tonnes) & 125 & 175 & 260 & 310 & 450 & 520 \\
\hline
\end{tabular}



Answer :

Certainly! Let's proceed step-by-step to create a simple bar diagram for the cement production data from 2018 to 2023. Here is a detailed explanation:

### Step-by-Step Solution

1. Understand the Data:
- We are given the production data for cement over six years, from 2018 to 2023:
- 2018: 125 M. Tonnes
- 2019: 175 M. Tonnes
- 2020: 260 M. Tonnes
- 2021: 310 M. Tonnes
- 2022: 450 M. Tonnes
- 2023: 520 M. Tonnes

2. Organize the Data:
- Create a table or list that correlates the years with their respective production values.

3. Determine the Axes:
- The horizontal axis (x-axis) will represent the years (2018 to 2023).
- The vertical axis (y-axis) will represent the production in million tonnes (M. Tonnes).

4. Plot the Bars:
- For each year, draw a vertical bar where the height of the bar corresponds to the production value of that year.

5. Label the Diagram:
- Title: "Cement Production of a Factory (2018-2023)"
- x-axis label: "Year"
- y-axis label: "Production (in M. Tonnes)"
- Ensure each bar is labeled with the corresponding year at the bottom.

### Drawing the Bar Diagram

1. Draw the Axes:
- Draw a horizontal line for the x-axis and a vertical line for the y-axis.

2. Mark the Years on the x-axis:
- Mark the points on the x-axis corresponding to the years 2018, 2019, 2020, 2021, 2022, and 2023. Space these points evenly.

3. Mark the Production Values on the y-axis:
- Choose a suitable scale for the y-axis. For example, you might use increments of 50 M. Tonnes per tick mark on the y-axis (0, 50, 100, 150, ... up to the maximum value slightly above 520).

4. Draw the Bars:
- For each year, draw a vertical bar starting from the year mark on the x-axis. The height of each bar should correspond to the production value for that year:
- For 2018 (125 M. Tonnes), draw a bar reaching up to 125 on the y-axis.
- For 2019 (175 M. Tonnes), draw a bar reaching up to 175 on the y-axis.
- For 2020 (260 M. Tonnes), draw a bar reaching up to 260 on the y-axis.
- For 2021 (310 M. Tonnes), draw a bar reaching up to 310 on the y-axis.
- For 2022 (450 M. Tonnes), draw a bar reaching up to 450 on the y-axis.
- For 2023 (520 M. Tonnes), draw a bar reaching up to 520 on the y-axis.

5. Add Labels:
- Add the title "Cement Production of a Factory (2018-2023)" at the top.
- Label the x-axis as "Year" and the y-axis as "Production (in M. Tonnes)".
- Optionally, you can label the top of each bar with its corresponding production value for clarity.

### Example Diagram

```

This simple bar diagram accurately represents the cement production data for each year clearly and concisely. The height of each bar gives a visual impression of the production quantity for each respective year.
