Based on a filter date, the dashboard script looks up the max date in the filter that is not greater than today and defaults to that date. The only addition, would be to create a date range instead of defaulting to a single value. The script also prints out all the filter dimensions to the browser console to be customized on, so we suggest checking out the console once you apply the script.
var defaultFilterConfig = {
dim1: "[DIM_DATE.DATE (Calendar)]"
};
dashboard.on('initialized', function(d, args) {
//print out all dimensions
for(var i=0; i<args.dashboard.filters.$$items.length; i++) {
if(args.dashboard.filters.$$items[i].levels != null) { //this is for dependent filters
for(var j=0; j<args.dashboard.filters.$$items[i].levels.length; j++) {
console.log(args.dashboard.filters.$$items[i].levels[j].dim);
}
}
else { //normal filters
console.log(args.dashboard.filters.$$items[i].jaql.dim);
}
}
//query the filter dimension to retrieve all members sorted descending
var dimJaql = '{"dim": "' + defaultFilterConfig.dim1 + '", "sort": "desc"}';
var query = '{"datasource": ' + JSON.stringify(args.dashboard.datasource) + ', "metadata": [' + dimJaql + ']}';
var url = '/api/elasticubes/' + args.dashboard.datasource.title + '/jaql';
$.ajax({
async:false,
method: 'POST',
url: url,
data: query,
success: function(result) {
//find the date that is most up to date based on today
for(var x=0; x<result.values.length; x++) {
if(result.values[x][0].data.substring(0,10) <= (new Date()).toISOString().substring(0,10)) {
break;
}
}
for(var i=0; i<args.dashboard.filters.$$items.length; i++) {
if(args.dashboard.filters.$$items[i].levels != null) { //this is for dependent filters
for(var j=0; j<args.dashboard.filters.$$items[i].levels.length; j++) {
if(defaultFilterConfig.dim1 === args.dashboard.filters.$$items[i].levels[j].dim) {
args.dashboard.filters.$$items[i].levels[j].filter = {
explicit: true,
