Stock navigator only accepts date and time as xaxis. Can it accept any data as xaxis, for example, depth in meter?
Navigator accepts the same data as any regular series (line, column etc.). It's designed to improve date-time formats, but you can rework it using some options:
- change tick positions using tickPositioner: https://api.highcharts.com/highstock/navigator.xAxis.tickPositioner
- change labels using labels.formatter: https://api.highcharts.com/highstock/navigator.xAxis.labels.formatter
