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.

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.

1. Understand the Data:
- We are given the production data for cement over six years, from 2018 to 2023:
- 2018: 125 M. Tonnes

- 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.

- 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.

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.
