@lageiger,
Indexlabels seems to be working fine across all chart-types including line, spline, area, column, etc. Please check for any typos and check browser-console for any error.
If the issue still persists, kindly create JSFiddle reproducing the issue you are facing and share it with us so that we can look into the code, understand the scenario better and help you resolve.
