Please, be patient!** This notebook displays shot sequences for professional tennis rallies as an interactive [Sunburst chart](https://datavizcatalogue.com/methods/sunburst_diagram.html). Each shot is represented by an arc with colors corresponding to different shot types. Sequences are put together by traversing concentric circles from the center outward. The angle span of each arc represents the count of shots with the corresponding sequence of previous shots. Explore the chart by: * **hovering over arcs** to display sequence paths * **clicking on arcs** to select paths * **double-clicking on arcs** to zoom in on them and see following shots * **double-clicking on the center circle** to zoom out one step at a time or **on breadcrumbs** on the right to zoom out to the corresponding shots * filtering sequences and extracting sub-sequences by using the "sequence pattern" and "where condition" boxes (see explanations and examples how to use them below the chart) * modifying, replacing, combining and splitting events by using the "rules to modify events" box (see explanations and examples how to use them below the chart) Professional tennis shot-by-shot data is from [Jeff Sackmann](http://www.jeffsackmann.com/)'s [Match Charting Project dataset](https://github.com/JeffSackmann/tennis_MatchChartingProject), filtered, cleaned up and re-organized ([notebook](https://observablehq.com/@mikpanko/tennis-shot-by-shot-data)). ------------ `33:T1348,viewof modifyEventsRules = { // set up initial rules let rules = urlParams.has("modifyEventsRules") ?

Their syntax is inspired by [pattern encoding in the graph query language Cypher](https://neo4j.com/docs/cypher-manual/current/syntax/patterns/) and [regular expressions](https://en.wikipedia.org/wiki/Regular_expression) but is much simpler to learn and use. Here is the syntax: **"()"** - matches any one event **"(:name)"** - matches one event called "name" ("_eventName" property) **"(:name1|name2)"** - matches one event called "name1" OR "name2" **"(!:name)"** - matches one event NOT called "name" **"({prop1=propName, prop2>=3, prop3!=1|2})"** - matches one event with properties: "prop1" equal to "propName", "prop2" greater or equal 3 and "prop3" not equal 1 or 2. Supported operators include: "==", "=" and ":" (all represent "equal"), "!=", ">", "<", ">=" and "<=". **"[3]\\()"** - matches any event subsequence of length 3 **"[0..5]\\()"** - matches any event subsequence of length 0 to 5 events **"[2..]\\()"** - matches any event subsequence of length 2 or more events **"[..4]\\()"** - matches any event subsequence of length 0 to 4 events **"[..]\\()"** - matches any event subsequence of any length **"[2..3]"** - matches any event subsequences of length 2 to 3 events Basically, an event pattern consists of "[...]" part encoding the possbile count of events followed by "(...)" part encoding the constraints of each event. If "[...]" part is missing, it defaults to one event ("[1]"). If "(...)" part is missing, it defaults to any event ("()"). All the above rules can be combined IN THE ORDER INTRODUCED ABOVE, for example: "[..5]\\(!:name1|name2 {prop1=5|6, prop2!=propName1|propName2})". To match a sequence of different events, separate them with one or more "-" symbols: **"(:name1)-(:name2)"** - matches one event called "name1" immediately followed by one event called "name2" **"[1..2]\\(:name1|name2)--[2]\\(:name3)"** - matches 1 or 2 events called "name1" or "name2" immediately followed by 2 events called "name3" **"(:name1)-[..3]-(:name2)"** - matches one event called "name1" later followed by one event called "name2" with any events in between but no more than 3 of them To match the start or end of a sequence, use "|" symbol: **"|-(:name)-..."** - matches one event called "name" at the start of a sequence **"...-(:name)-|"** - matches one event called "name" at the end of a sequence Omitting "|" at the start or end of a pattern string defaults to matching any number of any events in a sequence before or after, respectively, the explicitly matched sub-sequence. So "-(:name1)-(:name2)" pattern string matches any sequences, which have one event called "name1" immediately followed by one event called "name2" ANYWHERE inside of it. There are a few rules for specifying whether a match should represent a whole sequence or only some part of it. They are handy for extracting and modifying sub-sequences via extractPattern() and modifyPattern() functions, respectively. Here is the syntax: **"-(:name)-..."** - starts a match from the start of a sequence (equivalent to "|-[..]-(:name)-...") **"(:name)-..."** - starts a match from event called "name" but a matching sequence can have other events before it **"-(:name1)-(^:name2)-..."** - starts a match from event called "name2" **"^-(:name1)-..."** - starts a match from the start of a sequence **"...-($:name1)-(:name2)-..."** - ends a match at event called "name1" **"...-(:name1)-$"** - ends a match at the end of a sequence **"-(:name1)-[1..3]\\(^$:name2)-(:name3)-..."** - collapses a match to only a 1-3 event sub-sequence of events called "name2" Finally, it is possible to specify meta-parameters and sequence-level properties with a "<...>" part, which needs to be placed at the end of a pattern string after an event pattern part: **"...<_whereToMatch=_ALL>"** - extracts ALL matches in a sequence, so it can split a sequence into several sub-sequences. Default value is "_FIRST", which extracts only the first match for each sequence. **"...<_allowOverlaps=true>"** - extracts all overlapping matches in a sequence (if "_whereToMatch" equals "_ALL"). Default value is "false", which starts the next match within a sequence after the end of a previous match. **"...< seqProp1=name1|name2, seqProp2!=3 >"** - matches sequences with sequence-level properties: "seqProp1" equal to "name1" or "name2" and "seqProp2" not equal to 3 All SPACES in a pattern strings are ignored, so you can add them as you please for better readability. Pattern string syntax is easy to master, apply and read; nevertheless, it provides a powerful interface to express almost any desired sequence question. `37:T564,md` ### Where Condition String Syntax Occasionally, sequence pattern alone might be not enough to filter to desired sequences to answer a data exploration question. This can happen when we need complex event- or sequence-level property matching, for example, computing timestamp difference between events. In such cases, an additional WHERE condition can help do the job. It pairs with a sequence pattern and provides an opportunity to define further filtering while seeing the context of all matched events. First, use **"(codename)"** in a sequence pattern string to give some event a codename "codename". Then use in whereCondition to define a filter. Where condition string is the **whereString** string inside the following function: function whereConditionFunction(ev, seq) { return eval(whereString); } It needs to return a boolean when evaluated by the eval() function and can use the following variables: * **ev** - object with keys equal to codenames of events matched through matchPattern() and values equal to corresponding sequence events. Because each event in a pattern can match a sub-sequence of more than one event in a sequence, each "ev" property is a list of all matched sequence events. * **seq** - sequence object for the corresponding sequence. `38:T4dd,md` ### New Event Names String Syntax The string producing the names of events to replace events or sub-sequences matched through a pattern. It can contain new event names directly or provide a formula to compute them based on event-level properties of matched events and sequence-level properties. It is the **newEventNames** string inside the following function: function newEventNamesFunction(ev, seq) { return eval(newEventNames); } It needs to return an array of strings or a string (if only one new event name) when evaluated by the eval() function and can use the following variables: * **ev** - object with keys equal to codenames of events matched through matchPattern() and values equal to corresponding sequence events. Because each event in a pattern can match a sub-sequence of more than one event in a sequence, each "ev" property is a list of all matched sequence events. * **seq** - sequence object for the corresponding sequence. There is a reserved event name "_REMOVE". It is treated as an instruction not to add a new event, so it can be used to remove events or replace events with sequences of varying lengths. ------------ `39:T7e2,// re-organize data into an
