@@ -71,7 +71,7 @@ The transform of the scale both defines how the input data is parsed as well as
 * `sqrt`: Creates a mapping between the square root of the input to the output range.
 * `square`: Inverse of `sqrt` transform
 * `asinh`: Creates a mapping between the inverse hyperbolic sine of the input to the output range. This approaches the natural logarithm but is well defined for negative values as well, which can make it a good choice for transforming values that exhibit logarithmic growth but span positive and negative values.
-* `pseudo_log`/`pseudo_log2`/`pseudo_ln`: A slightly different transform that exhibit the same characteristics as `asinh` but where it is possible to choose the base of the logarithm it should approach.
+* `pseudo_log`/`pseudo_log2`/`pseudo_ln`: A slightly different transform that exhibits the same characteristics as `asinh` but where it is possible to choose the base of the logarithm it should approach.
 * `integer`: Like `linear` but will convert input to integer by removing the decimal part.
 * `date`: Default when mapping a DATE column. Like `linear` but will cast input to date if not already (for strings this assumes the date is formatted as YYYY-MM-DD, for numbers it will be the number of days since 1970-01-01).
 * `datetime`: Default when mapping a DATETIME column. Like `linear` but will cast input to datetime if not already (for strings a range of different permutations of the YYYY-MM-DDTHH:MM:SS.fTZ is tried, for number it will be the number of microseconds since 1970-01-01T00:00:00).
