Build a time-commitment heatmap

A time-commitment heatmap visually represents the amount of time spent on various tasks or activities over a given period. The heatmap uses color gradients to indicate the intensity of the time spent. Darker or more intense colors typically represent more time, while lighter colors show less time. You can build a time-commitment heatmap using various tools such as Excel, Google Sheets, or visualization libraries in programming languages like Python (with libraries like matplotlib, seaborn, etc.).

Here’s a step-by-step approach to build a basic time-commitment heatmap:

1. Gather Data:

You need to know what tasks you are measuring and the time periods involved (e.g., days, weeks, hours). A simple example could be tracking time spent on tasks throughout a workweek (Monday to Friday).

Example dataset:

In this case, the task is tracked by day, with time spent in hours.

2. Choose Visualization Tool:

You can use Excel, Google Sheets, or a programming language to create the heatmap. Here are the two most common options:

Option A: Using Google Sheets or Excel

• Step 1: Input the data into a spreadsheet with tasks as rows and days as columns.

• Step 2: Highlight the entire table and choose the “Conditional Formatting” option.

• Step 3: Select a color scale (you can choose from a pre-set scale or customize one) to indicate the intensity of time spent (e.g., a color gradient where dark red represents high time commitment and light green represents low time commitment).

Option B: Using Python (Matplotlib/Seaborn)

1. Install Necessary Libraries:
   If you haven’t already, you need to install matplotlib and seaborn. You can do this by running:

   bash
   CopyEdit
   pip install matplotlib seaborn
   

2. Write Python Code:

python
CopyEdit
import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd

# Create a dataset (similar to the one above)
data = {
    'Task': ['Emails', 'Meetings', 'Coding', 'Research', 'Breaks'],
    'Monday': [2, 1, 5, 3, 1],
    'Tuesday': [3, 2, 4, 1, 1],
    'Wednesday': [1, 2, 6, 2, 1],
    'Thursday': [2, 1, 4, 3, 1],
    'Friday': [2, 1, 5, 4, 1]
}

# Convert the data into a DataFrame
df = pd.DataFrame(data)
df.set_index('Task', inplace=True)

# Create a heatmap
plt.figure(figsize=(10, 6))
sns.heatmap(df, annot=True, cmap="YlGnBu", linewidths=0.5, cbar_kws={'label': 'Time in hours'})
plt.title('Time Commitment Heatmap')
plt.show()

This code generates a heatmap showing time commitments for each task across days. The color scale YlGnBu (Yellow-Green-Blue) is used here, but you can adjust it as needed.

3. Interpretation:

• High-Intensity Colors (e.g., dark shades of blue) represent tasks that required more time.

• Low-Intensity Colors (e.g., light shades) represent tasks that required less time.

• By visually inspecting the heatmap, you can quickly assess which tasks are consuming the most time on specific days.

Example Result in Python:

A heatmap generated by the above Python code might look like this:

• Tasks like Coding may appear in darker colors, indicating high time commitment.

• Tasks like Emails or Meetings could have lighter colors, indicating less time spent.

4. Refinement:

You can refine the heatmap by:

• Adjusting the color palette to make the intensity more distinguishable.

• Adding labels, legends, or annotations to provide context.

• Setting custom time periods (e.g., hours, weeks, months).
