Below 350 nm, however, they clearly mismatch. This mismatch is not evident in the linear plot below, which was plotted with the same data. One drawback of the log plot is that it tends to compress the data at the top end, giving the appearance that the bandwidth is wider than it actually is. The log plot might mislead you into believing that the curves approximate the UVA band. As you can see in the linear plot, neither curve would adequately cover the UVA bandwidth.
Most people are familiar with graphs that utilize linearly scaled axes.
This type of graph is excellent at showing bandwidth, which is usually judged at the 50 percent power points. In the log plot of the same data, both curves appear to fit nicely within the UVA band. This type of graph is poor at showing the effectiveness of a spectral match across an entire function. The two responses in the linear plot appear to match fairly well. Many companies, in an attempt to portray their products in the best possible light, graph detector responses on a linear plot in order to make it seem as if their detector matches a particular photo-biological action spectrum, such as the Erythemal or Actinic functions.
