# Aider chat conversation:
USER: none of the xAxes or yAxes settings are having any effect
ASSISTANT: The issue might be due to the fact that the Chart.js version you are using has different configuration options. Let's update the configuration to use the latest Chart.js settings.
Here are the changes:
_posts/2024-05-13-models-over-time.md
```markdown
<<<<<<< SEARCH
scales: {
xAxes: [{
type: 'time',
time: {
unit: 'month',

return new Date(value).toLocaleDateString();
}
},
scaleLabel: {
display: true,
labelString: 'Release Date'
}
}],
yAxes: [{
scaleLabel: {
display: true,

type: 'time',
time: {
unit: 'month',

},

callback: function(value, index, values) {
return new Date(value).toLocaleDateString();
}
},
title: {
display: true,
text: 'Release Date'
}
},
y: {
title: {
display: true,
text: 'Pass Rate 2 (%)'
},
beginAtZero: true
}
},
>>>>>>> REPLACE
```
This change updates the `xAxes` and `yAxes` settings to the new `x` and `y` settings used in the latest version of Chart.js.
# Aider chat conversation:
USER: the dates aren't being shown as dates on the x-axis. they are coming out as large integers like 1,888,000,000,000
ASSISTANT: To fix the issue with the dates not being shown correctly on the x-axis, we need to modify the `xAxes` configuration in the Chart.js options. Here's the *SEARCH/REPLACE block* with the necessary changes:
_posts/2024-05-13-models-over-time.md
```markdown
<<<<<<< SEARCH
xAxes: [{
type: 'time',
time: {

tooltipFormat: 'll'

tooltipFormat: 'll',
parser: 'YYYY-MM-DD'
},
ticks: {
callback: function(value, index, values) {
return new Date(value).toLocaleDateString();
}
},
>>>>>>> REPLACE
```
The changes made are:
1. Added the `parser: 'YYYY-MM-DD'` option to the `time` configuration to specify the date format used in the data.
2. Added a `ticks.callback` function to format the tick labels on the x-axis as localized date strings.
These modifications should ensure that the dates are displayed correctly on the x-axis of the scatter plot.
# Aider chat conversation:
USER: the dates aren't being shown as dates on the x-axis. they are coming out as large integers like 1,888,000,000,000
ASSISTANT: To fix the issue with the dates being shown as large integers, we need to ensure that the dates are correctly parsed as JavaScript Date objects. We can achieve this by modifying the data processing part of the script.
Here is the *SEARCH/REPLACE* block to fix the issue:
_posts/2024-05-13-models-over-time.md
```markdown
<<<<<<< SEARCH
x: new Date('{{ row.released }}'),
=======
x: new Date('{{ row.released | date: "%Y-%m-%dT%H:%M:%S" }}'),
>>>>>>> REPLACE
```
This change ensures that the date string is correctly formatted for JavaScript's `Date` object.
# Aider chat conversation:
USER: draw a scatter plot of the edit_leaderboard models which have `released` dates. With x as the release date, y as the `pass_rate_2` and label each point with the `model` name field. use a chart style similar to the bar graph in the leaderboard.md, but we want a scatter plot for this one. put the scatter plot in the new blog post
ASSISTANT: Let's add the scatter plot to the new blog post in `_posts/2024-05-13-models-over-time.md`.

# Aider chat conversation:
USER: but it's a 1060 wide by 1080 high video, not 16:9
ASSISTANT: You're right, the video dimensions are 1060x1080, which is not a 16:9 aspect ratio. To maintain the original aspect ratio of the video, we can calculate the padding-bottom percentage based on the video's height divided by its width. Here are the updated changes:
_posts/2024-05-02-browser.md
<source>
<<<<<<< SEARCH
<style>
.video-container {
position: relative;
padding-bottom: 56.25%; /* 16:9 aspect ratio */
height: 0;
overflow: hidden;
}
.video-container video {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
</style>
=======
<style>
.video-container {
position: relative;
padding-bottom: 101.89%; /* 1080 / 1060 = 1.0189 */
height: 0;
overflow: hidden;
}
.video-container video {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
</style>
>>>>>>> REPLACE
</source>
The change:
1. Update the `padding-bottom` value to `101.89%`, which is calculated by dividing the video's height (1080) by its width (1060) and multiplying by 100 to get a percentage.
This change will ensure that the responsive video container maintains the original aspect ratio of the 1060x1080 video.
# Aider chat conversation:
USER: the video overflows the width of the browser on mobile
ASSISTANT: To fix the video overflowing the width of the browser on mobile devices, we can add some CSS styles to make the video responsive. Here are the changes:
_posts/2024-05-02-browser.md
<source>
<<<<<<< SEARCH
<video width="1060" height="1080" controls loop poster="/assets/browser.jpg">
<source src="/assets/aider-browser-social.mp4" type="video/mp4">

</div>
<style>
.video-container {
position: relative;
padding-bottom: 56.25%; /* 16:9 aspect ratio */
height: 0;
overflow: hidden;
}
.video-container video {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
</style>
>>>>>>> REPLACE
</source>
The changes:
1. Wrap the `<video>` element inside a `<div>` with class `video-container`.
2. Remove the `width` and `height` attributes from the `<video>` element.
3. Add a `<style>` block with CSS for the `video-container` class:
- Set `position: relative` on the container.
- Use `padding-bottom: 56.25%` to maintain a 16:9 aspect ratio.
- Set `height: 0` and `overflow: hidden` to contain the video.
4. Add CSS for the `video` element inside `video-container`:
- Set `position: absolute` to position it within the container.
- Set `top: 0`, `left: 0`, `width: 100%`, `height: 100%` to make it fill the container.
These changes will make the video responsive and fit within the width of the browser on mobile devices while maintaining its aspect ratio.
# Aider chat conversation:
