* Template variables are `{.}`, `{a}`, `{b}`, `{c}`, `{d}`.
*`{.}` is the dot of the corresponding color of `serie` that is currently indicated or whose `index` is `0`.`
*`{a}` is the `name` of the `serie` that is currently indicated or whose `index` is `0`.
*`{b}` is the `name` of the `serieData` that is currently indicated or whose `index` is `0`, or a `category` value (such as the X-axis of a line chart).
*`{c}` is the value of a Y-dimension (`dimesion` is 1) from the `serie` that is currently indicated or whose `index` is `0`.
*`{d}` is the percentage value of Y-dimensions (`dimesion` is 1) from the `serie` that is currently indicated or whose `index` is `0`, with no `%` sign.
*`{.1}` represents a dot from serie corresponding color that specifies `index` as `1`.
*`1` in `{a1}`, `{b1}`, `{c1}` represents a `serie` that specifies an `index` of `1`.
*`{c1:2}` represents the third data from `serie`'s current indication data item indexed to `1` (a data item has multiple data, `index` 2 represents the third data).
*`{c1:2-2}` represents the third data item from `serie`'s third data item indexed to `1` (i.e., which data item must be specified to specify).
*`{d1:2: F2}` indicates that a formatted string with a value specified separately is `F2` (`numericFormatter` is used when not specified).
*`titleFormatter`: The string template formatter for the tooltip title content. Support for wrapping lines with `\n`. This is only valid if the `itemFormatter` is in effect. The placeholder `{I}` can be set separately to indicate that the title is ignored and not displayed.
*`itemFormatter`: a string template formatter for a single Serie or data item content. Support for wrapping lines with `\n`. When `formatter` is not null, use `formatter` first, otherwise use `itemFormatter`.
*`numericFormatter`: Standard numeric format string. Used to format numeric values to display as strings. Using 'Axx' form: 'A' is the single character of the format specifier, supporting 'C' currency, 'D' decimal, 'E' exponent, 'F' number of vertices, 'G' regular, 'N' digits, 'P' percentage, 'R' round tripping, 'X' hex etc. 'XX' is the precision specification, from '0' - '99'. see: <https://docs.microsoft.com/zh-cn/dotnet/standard/base-types/standard-numeric-format-strings>
