Thanks for the feature request. While I agree it would be ideal to support more customisation for date binning in the product, it is possible to get what you want by using calculated fields: 1. Create a new calculated field called "weekDay" with the following formula, replacing "yourDateField" with the name of the field you are using: { $dayOfWeek: "$yourDateField" } 2. Create a new calculated field called "spanishWeekday" with the following formula. Note that I am translating the numbers from the first calculated field into Spanish but also prefixing with a new number to influence the sort order. { $switch: { branches: [ { case: { $eq: [ "$weekDay", 1 ] }, then: "7. Domingo" }, { case: { $eq: [ "$weekDay", 2 ] }, then: "1. Lunes" }, { case: { $eq: [ "$weekDay", 3 ] }, then: "2. Martes" }, { case: { $eq: [ "$weekDay", 4 ] }, then: "3. Miércoles" }, { case: { $eq: [ "$weekDay", 5 ] }, then: "4. Jueves" }, { case: { $eq: [ "$weekDay", 6 ] }, then: "5. Viernes" }, { case: { $eq: [ "$weekDay", 7 ] }, then: "6. Sábado" } ], default: "n/a" } } 3. Use the new "spanishWeekday" field on the category axis of you chart, and choose to sort by Category in ascending order.
