docstr: Sets the step in-between ticks on this axis. Use with `tick0`.
  Must be a positive number, or special strings available to
  "log" and "date" axes. If the axis `type` is "log", then ticks
  are set every 10^(n*dtick) where n is the tick number. For
  example, to set a tick mark at 1, 10, 100, 1000, ... set dtick
  to 1. To set tick marks at 1, 100, 10000, ... set dtick to 2.
  To set tick marks at 1, 5, 25, 125, 625, 3125, ... set dtick to
  log_10(5), or 0.69897000433. "log" has several special values;
  "L<f>", where `f` is a positive number, gives ticks linearly
  spaced in value (but not position). For example `tick0` = 0.1,
  `dtick` = "L0.5" will put ticks at 0.1, 0.6, 1.1, 1.6 etc. To
  show powers of 10 plus small digits between, use "D1" (all
  digits) or "D2" (only 2 and 5). `tick0` is ignored for "D1" and
  "D2". If the axis `type` is "date", then you must convert the
  time to milliseconds. For example, to set the interval between
  ticks to one day, set `dtick` to 86400000.0. "date" also has
  special values "M<n>" gives ticks spaced by a number of months.
  `n` must be a positive integer. To set ticks on the 15th of
  every third month, set `tick0` to "2000-01-15" and `dtick` to
  "M3". To set ticks every 4 years, set `dtick` to "M48"
  
  The 'dtick' property accepts values of any type
