The 24-hour time range is broken down into 48 half-hour line plots. The line colour changes from blue to red every two hours to improve readability. , while the small text below the plot indicates the option selected (in some cases they may differ depending on filter and channel availability). If a channel option is selected which states that the channels will be overlaid, the high-rate and low-rate data of the same orientation will be overlaid. This is to fill in the gaps on high-rate data that has been diverted by the military with the low-rate data. When overlaid, the high-rate data is brought to the front and coloured blue and red. The low-rate data is coloured grey. The line spacing is specified below the plot, in a comment footer, to provide users an indication of scale. Also in this text below the plot is a comment stating a change in low-rate filter if one occurred (the title of the plot indicates the channel(s) and filters actually used). The line spacing is dependent on the channels being plotted. If the time range is after March 1st, 2013 for Barkley Canyon, Clayoquot Slope or Main Endeavour Field, or after September 5th 2013 for Cascadia Basin, the sample rates are 200 samples per second (H* channels) or 8 samples per second (M* channels), and the line spacing is 2.9e-06 m/s (vertical velocity), 3.2e-06 m/s (horizontal velocity) and 125 m/s2 (acceleration). If the time-range is before March 1st 2013 for Barkley Canyon, Clayoquot Slope or Main Endeavour Field, or before September 5th 2013 for Cascadia Basin, the sample rates are 100 samples per second (H* channels) and 1 sample per second (L* channels). All velocity line spacing is 5e-05 m/s and all acceleration line spacing is 0.125 m/s2. The difference in line spacing is due to difference in noise on the channel and in an attempt to produce a clear plot with a consistent scaling. Scale factors are accessible in device attributes and are easily modified. Here is an example of a seismometer daily trace plot:
