Zooming in on a fractalish plot
by John from John D. Cook on (#6YA6Z)
The exponential sum of the day page on my site draws an image every day by plugging the month, day, and year into a formula. Details here.
Today's image looks almost solid blue in the middle.
The default plotting line width works well for most days. For example, see what the sum of the day will look line on July 1 this year. Making the line width six times thinner reveals more of the detail in the middle.
You can see even more detail in a PDF of the plot.
