Taking the code at https://developers.google.com/chart/interactive/docs/reference#patternformatter as an example.
The data looks like this data.addRows([ ['John Lennon', '[email protected]'], ['Paul McCartney', '[email protected]'], ['George Harrison', '[email protected]'], ['Ringo Starr', '[email protected]'] ]); But suppose the data looks like this: data.addRows([ ['John Lennon', ''], ['Paul McCartney', '[email protected]'], ['George Harrison', ''], ['Ringo Starr', '[email protected]'] ]); The formatter looks like this: *var formatter = new google.visualization.PatternFormat( '<a href="mailto:{1}";>{0}</a>');// Apply formatter and set the formatted value of the first column.formatter.format(data, [0, 1]);* Is it possible to conditionally apply the PatternFormat so that if the email data is empty then the formatter is not applied? I know I could create a new column by stepping through the data, and creating and populating that with either the name or the name and an email link, but then the column sorting is not going to work properly because it's gong to sort on "<" as well as the name. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
