      where
      1. 'vt' -- The value type:
        1. 'uv' -- Hydrograph for unit value (default).
        2. 'dv' -- Hdyrograph for daily value.
      2. 'cd' -- a USGS parameter code.
        1. For discharge or stage, just specify '00060' or '00065', respectively.
        2. For other paramter, a 'dd' number must be added to code as <code>_<dd>. For example, to get a 'presentation' graph of temperature at 07144100, the code is '00010_27'
      3. 'site_no' -- a USGS site number
      4. 'log' -- an indicate to draw 'log-scale' on y-axis for 'discharge'
      5. 'p' -- Specify the time length in days.
