CircHist creates circular (polar) histograms from angle data, either distribution data or already-binned data. Works with circular and axial (bimodal) data. Circular statistics (average angle, 95 % confidence interval, resultant vector length, Rayleigh test of uniformity and circular-linear correlation) are automatically calculated using the CircStat Toolbox (https://github.com/circstat/circstat-matlab) and are graphically included. All visual properties can be dynamically adjusted; see @CircHist/html/exampleCircHist.html for usage examples. This function is conceptually similar to MATLAB's ROSE and POLARHISTOGRAM functions, but differs from them in several respects:
- Instead of plotting the histogram bins as wedges, they are plotted as straight bars.
- The histogram bins can have error bars.
- The radius-axis scale is shown as a straight scale next to the plot.
- Circular statistics are automatically computed.
- Arrows with specific direction and length can be overlayed.

Thank you for your reply -- I checked (hopefully) all functions that are called by the code and determined the minimum MATLAB version required: R2017a.
It would be possible to reduce it to R2016a, where POLARAXES was introduced, but this is a fundamental part of the code, so I cannot provide a fix -- sorry for the inconvenience.
requires polaraxes that I don't have
The function THETATICKFORMAT was introduced in MATLAB R2016b, is it possible that you use an older version than this?
In any case, this function is just a shortcut to change the respective axes-property, so I might just change my code to refer to this property directly, then older MATLAB versions without THETATICKFORMAT will be supported.
There is an error when running this:
Undefined function or variable 'thetatickformat'.
