    • Sorting. When the x-axis shows the timestamp, it can't be sorted and its natural chronological order is kept.

      Available sorting methods when the x-axis is not time-based:

      • By label Option available from version 1.212 Sorts based on the text/values of their labels (categories). Uses "natural ordering" of categorical values: for example, text is sorted alphabetically ("Apple" comes before "Banana"); numbers are sorted numerically ("2" comes before "10"); mixed alphanumeric values are sorted intelligently ("Host2" comes before "Host10").

        Valid options are:

        • Ascending

        • Descending

      • Set by query default sorting when the x-axis is not time-based. It maintains the order from the query results (same as no sorting).

    • Max label length

      Slider to set the length of labels in the vertical axis, in pixels.

    • Show Title

      Checkbox to show/hide the title assigned to the vertical axis.
