FacetChart feature - ascending sort order

[chee_yan_yeong]

Based on the documentation, zoomcharts contains only one sorting feature which is 'sortField' (by descending) as shown at below:
https://zoomcharts.com/developers/en/facet-chart/api-reference/settings/data.html#doc_sortField
Is that possible to add in sortField by ascending feature?

Then, despite sort by series, is that possible to add in manual sort for x axis items? Eg:

For the table on above, the users are allowed to sort the X items manually which do not depend on value for Y, like a-b-c-d, d-c-b-a, a-d-b-c, etc.

If you omit the sortField or specify null (the default) then the chart will preserve the order in the data source.

For version 1.12 we just added the ability to specify -value (note the prefix -) which will result in ascending sort order.

We used this approach instead of adding another field like sortAscending since this will allow future version to implement something like sortField: "category, -value".
