Adding these whitepapers and books to the resources of your analytics community can lead to a deeper understanding and internalization of visual best practices. You can find a list of books by renowned data visualization experts in the appendix. Here are a few whitepaper links to share on your enablement intranet: It is important not to assume that people automatically know what it takes to clearly and effectively communicate with data. Dashboards should have interactive elements that are discoverable and predictable, follow a sensible, logical layout, and have a simplified design that makes complex decisions easier. Think not just as an analyst but also as a designer and consumer. Even a beautiful dashboard with an interesting data source could be rendered useless if your audience can’t use it to discover insights. A dashboard is successful when people can easily use it to derive answers. This Kibana plugin is inspired from computed-columns and kbn_searchtables plugins.Visual best practices are key to developing informative visualizations that drive your audience to act. Versions and Release Notes are listed in Releases page Credits Removes duplicates from provided array so that array contains only unique values. Removes whitespace from both ends of a string. colRef is either the column label (ex: 'Count') or the column index (ex: 1). Returns column total referenced by colRef (if it exists), or else defaultValue. Returns the calling string value converted to uppercase. Returns the calling string value converted to lowercase. Returns the sum of all split column values (only if 'Split cols' bucket is used). Returns the part of the string between the start and end indexes, or to the end of the string (if no index end is provided). Example for an array of numbers: comparator(a, b) = a - b sort(col0, comparator) A compare function can be provided to customize the sort order. Sorts the elements of an array in place and returns the sorted array.
Returns the index of the first match or -1 if not found. All the occurrences will be replaced.Įxecutes a search for a match between a regular expression on 'str' String. Returns a new string with all matches of a regexp replaced by a replacement.
Only the first occurrence will be replaced. Returns a new string with first match of substr replaced by a replacement. Useful to parse date columns in 'Document Table' visualization. If the argument doesn't represent a valid date, NaN is returned. Returns the number of milliseconds elapsed since Janu00:00:00 UTC and the date obtained by parsing the given string representation of a date. Returns the number of milliseconds elapsed since Janu00:00:00 UTC Returns the index within the calling String or Array object of the last occurrence of the specified value, searching backwards from fromIndex. Returns -1 if the value is not found.ĭetermines whether the passed value is an Array. Returns the index within the calling String or Array object of the first occurrence of the specified value, starting the search at fromIndex. Returns the count of all split columns (only if 'Split cols' bucket is used).Įncodes the provided string as a Uniform Resource Identifier (URI) component. Returns column value referenced by colRef (if it exists), or else defaultValue.
