+title: Drawing graphs with aider, GPT-4o and matplotlib
+excerpt: Use GPT-4o to draw graphs with matplotlib, including adjusting styles and making visual changes. You get the graph, but you also get the code in your repo.

+# Drawing graphs with aider, GPT-4o and matplotlib
+
+
+
+I recently wanted to draw a graph showing how LLM code editing skill has been
+changing over time as new models have been released by OpenAI, Anthropic and others.
+I have all the
+[data in the yaml file](https://github.com/paul-gauthier/aider/blob/main/_data/edit_leaderboard.yml) that is used to render
+[aider's LLM leaderboards](https://aider.chat/docs/leaderboards/).
+
+Below is the aider chat transcript, which shows:
+
+- I launch aider with the yaml file, a file with other plots I've done recently (so GPT can crib the style) and an empty file called `over_time.py`.
+- Then I ask GPT to draw the scatterplot I want.
+- I ask it to color the points for GPT-4 and GPT-3.5 family models differently, to better see trends within those model families.
+- I add a PNG of the graph to the chat, so GPT can see the current graph and understand why I ask it to move the point labels so they don't overlap the points.
+- I work through a series of other small style changes, like changing fonts and the graph border.
+
+In the end I have the graph, but I also have the python code in my repo.
+So I can update this graph easily whenever I add new entries to the yaml data file.
+
+
+
+> Aider v0.35.1-dev
+> Models: gpt-4o with diff edit format, weak model gpt-3.5-turbo
+> Added _data/edit_leaderboard.yml to the chat.
+> Added benchmark/over_time.py to the chat.
+> Added benchmark/plots.py to the chat.
+
+#### in over_time.py, draw a graph for each of the yaml entries with a `released` date. plot date on x, `pass_rate_2` on y and label with the `model` name. do a scatter plot. use colors/styles similar to the other graphs.
+
+To draw a scatter plot for each of the YAML entries with a `released` date, we need to:
+
+1. Read the YAML file.
+2. Extract the `released` date and `pass_rate_2` for each entry.
+3. Plot the data using matplotlib.
+
+Here are the changes:
+
+benchmark/over_time.py
+```python
+<<<<<<< SEARCH
+=======
+import matplotlib.pyplot as plt
+import yaml
+from datetime import datetime
+
+def plot_over_time(yaml_file):
+ with open(yaml_file, 'r') as file:
+ data = yaml.safe_load(file)
+
+ dates = []
+ pass_rates = []
+ models = []
+
+ for entry in data:
+ if 'released' in entry and 'pass_rate_2' in entry:
+ dates.append(datetime.strptime(entry['released'], '%Y-%m-%d'))
+ pass_rates.append(entry['pass_rate_2'])
+ models.append(entry['model'])
+
+ plt.figure(figsize=(10, 6))
+ plt.scatter(dates, pass_rates, c='blue', alpha=0.5)
+
+ for i, model in enumerate(models):
+ plt.annotate(model, (dates[i], pass_rates[i]), fontsize=8, alpha=0.75)
+
+ plt.xlabel('Release Date')
+ plt.ylabel('Pass Rate 2')
+ plt.title('Model Performance Over Time')
+ plt.grid(True)
+ plt.tight_layout()
+ plt.show()
+
+# Example usage
+plot_over_time('_data/edit_leaderboard.yml')

+
+The error indicates that the `released` field in the YAML file is already a `datetime.date` object, so we don't need to parse it with `datetime.strptime`. We can directly use it in the plot.
+
+Here are the changes:
+
+benchmark/over_time.py
+```python
+<<<<<<< SEARCH
+ dates.append(datetime.strptime(entry['released'], '%Y-%m-%d'))
+=======
+ dates.append(entry['released'])
+>>>>>>> REPLACE
+```
+
+> Applied edit to benchmark/over_time.py
+> Commit af2f4b7 aider: Use the `released` field directly in the plot instead of parsing it with `datetime.strptime`.
+
+#### color the "gpt-4" models differently
+
+To color the "gpt-4" models differently, we need to modify the plotting code in `benchmark/over_time.py` to check for "gpt-4" in the model name and assign a different color.
+
+Here are the changes:
+
+benchmark/over_time.py
+```python
+<<<<<<< SEARCH
+ plt.scatter(dates, pass_rates, c='blue', alpha=0.5)
+=======
+ colors = ['red' if 'gpt-4' in model else 'blue' for model in models]
+ plt.scatter(dates, pass_rates, c=colors, alpha=0.5)
+>>>>>>> REPLACE
+```
+
+This change will color the points red if the model name contains "gpt-4", otherwise, it will color them blue.

+> Commit 0d11357 aider: Color the "gpt-4" models differently.
+
+#### color the gpt-3.5 models a new color
+
+To color the "gpt-3.5" models a new color, we need to modify the plotting code in `benchmark/over_time.py` to check for "gpt-3.5" in the model name and assign a different color.
+
+Here are the changes:
+
+benchmark/over_time.py
+```python
+<<<<<<< SEARCH
+ colors = ['red' if 'gpt-4' in model else 'blue' for model in models]
+=======
+ colors = ['red' if 'gpt-4' in model else 'green' if 'gpt-3.5' in model else 'blue' for model in models]
+>>>>>>> REPLACE
+```
+
+> Applied edit to benchmark/over_time.py
+> Commit 85d9d84 aider: Color the "gpt-3.5" models green in the plotting code.
+
+#### use the colorscheme and fonts from the other graphs in plots.py
+
+To use the colorscheme and fonts from the graphs in `plots.py`, we need to:
+
+1. Import the necessary settings from `plots.py`.
+2. Apply these settings to the graph in `over_time.py`.
+
+Here are the changes:
+
+benchmark/over_time.py

+
+#### make the labels not overlap the dots
+
+To make the labels not overlap the dots, we can adjust the position of the labels slightly using the `xytext` parameter in the `annotate` function.
+
+Here are the changes:
+
+benchmark/over_time.py
+```python
+<<<<<<< SEARCH
+ ax.annotate(model, (dates[i], pass_rates[i]), fontsize=8, alpha=0.75)
+=======
+ ax.annotate(model, (dates[i], pass_rates[i]), fontsize=8, alpha=0.75,
+ xytext=(5, 5), textcoords='offset points')
+>>>>>>> REPLACE
+```

+> Applied edit to benchmark/over_time.py
+> Commit 75fa061 aider: Adjust the position of labels to prevent overlap with dots.
+
+
+#### make the dots bigger
+
+To make the dots bigger, we can adjust the `s` parameter in the `scatter` function, which controls the size of the dots.
+
+Here are the changes:
+
+benchmark/over_time.py
+```python
+<<<<<<< SEARCH
+ ax.scatter(dates, pass_rates, c=colors, alpha=0.5)
+=======
+ ax.scatter(dates, pass_rates, c=colors, alpha=0.5, s=100)

+
+#### make the border of the graph thinner and lighter
+
+To make the border of the graph thinner and lighter, we can adjust the `spines` properties of the axes.
+
+Here are the changes:
+
+benchmark/over_time.py
+```python
+<<<<<<< SEARCH
+ colors = ['red' if 'gpt-4' in model else 'green' if 'gpt-3.5' in model else 'blue' for model in models]

+ for spine in ax.spines.values():
+ spine.set_edgecolor('#DDDDDD')
+ spine.set_linewidth(0.5)
+
+ colors = ['red' if 'gpt-4' in model else 'green' if 'gpt-3.5' in model else 'blue' for model in models]
+>>>>>>> REPLACE
+```
