Why are the graphs for the distribution of light from the Sun as a function of (a) frequency and (b) wavelength not exactly reversed?

The color of the sun is white. The sun emits all colors of the rainbow in approximately equal amounts and we call this combination white. That is w...

What is the color of the sun?

I thought that the frequency of light was directly inverse to the wavelength by a constant. In other words, I assumed that graphing the frequency of light as a function of wavelength would be a straight inverse line. Because of that, the graphs for the distribution of light from the sun as functions of frequency and wavelength would be exactly the same, but reversed. Yet, this is not what is reported in the linked article. Even more confusing to me is that the different functions peak at different light. When as a function of frequency, the light peaks at infrared. When as a function of wavelength, the light peaks at violet.

What am I misunderstanding? Is the frequency of light not directly proportional to it's wavelength? Or is this something to do with the way we are measuring the light from the Sun?
