Used to display the number of documents associated to a field value (for example, for keywords: how many documents match a keyword?). Bars are sorted by descending number of documents.
Possible configuration: size
, color
, and maxItems
.
maxItems
limits the number of bars to its value (default value: 100
).
If you want to shorten the field value to display on the chart, use an associative array to replace too long fields values with shorter ones:
{
"field": "fields.Themes",
"type": "horizontalbars",
"title": "Themes (bars)",
"maxItems" : 10,
"labels": {
"Biology & Biochemistry" : "Bio & Bio",
"Pharmacology & Toxicology" : "Pharmaco & Toxico",
"Plant & Animal Science" : "Plant & Animal"
}
},
