Create a LineGraph with error bars. lowerErrors and upperErrors
must be input ranges with elements implicitly convertible to double for
error bars to be shown. Any other value, such as null or 0, will result
in no error bars being shown. Therefore, to only show, for example,
upper erros, simply pass in null or 0 for the lower errors.
To draw symmetric error bars, simply pass in the same range for
lowerErrors and upperErrors. However, note that if you do this,
the range will need to be a forward range, not an input range.
