AI Thread Summary
The discussion centers around a heat map representing temperature data, with time of day on the y-axis and time of year on the x-axis, created in Excel from weather data. Participants identify this type of data visualization as a "Heat Map," which can also be applied to solar radiation data. A tutorial link is shared for creating similar graphs, emphasizing that the instructor used individual Excel cells as colored pixels to construct the heat map, utilizing a grid of 24 rows and 365 columns. The conversation highlights the usefulness of heat maps for visualizing time series data.

The attached Image is a for some kind of heat map of temperature with the y-axis corresponding to the time of day and the x-axis corresponding to the time of year. It was generated in Excel from weather data files.

What is this type of data representation called? I've seen the same type of chart used for solar radiation as well. If you can point me to a tutorial on how to generate this type of graph, that would be :ok: too.

@Tom G Thanks much, really good video.

In case you're interested, the instructor was modeling a heat map in excel and I couldn't find a chart feature which did that. Turns out he used each individual cell as a colored pixel with 24 rows and 365 columns.

On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
