Not able to animate using traja.plotting.animate

[dhivya-jayaraman]

traja.plotting.animate(trj: TrajaDataFrame, polar = True, save = False)

Error:
File "<ipython-input-179-b9f35fc742bf>", line 2
    gsts_ais_grp.traja.plotting.animate(trj: TrajaDataFrame, polar = True, save = False)

I'm trying to animate a trajectory by using plotting.animate(). I'm not sure if trj is the dataframe or should it be like gsts_ais_grp.traja.plotting.animate(trj: TrajaDataFrame, polar = True, save = False). Either way I'm getting syntax error. Please help me with this. Thanks in advance!

The ability to call all methods through the traja accessor (df.traja...) was not previously possible. This feature has just been added to traja==0.2.0. Please upgrade to the new version and try again (ex: gsts_ais_grp.traja.animate()). Let me know if you have any further issues.

Sorry, I just realized the PyPI build did not complete. Please try again: https://pypi.org/project/traja/.

Hello Justin, sorry to keep bothering you. I'm not sure if I'm doing something wrong here. I have dataframe of id, lat, lon, time (in seconds) and distance (using traja.calc_displacement()). I'm trying to call the animate() function with traja version 0.2.0. It throws an attribute error.

id	x	y	time	distance
0001	47.743962	162.365457	0.0	NaN
0001	47.749235	162.447688	851.0	0.082401

[JustinShenk]

Sorry, the error you received was due to Traja expecting a TrajaDataFrame rather than pandas DataFrame. This has now been fixed in traja==0.2.1.

Let me know if you have any further issues.

I'm still getting the same error with pandas dataframe so I converted to traja dataframe which got it to work but I'm not sure it is animating. It just has 1 frame. The trajectory of the item which plotted using TrajaCollection() is shown in the figure below.

When I try to animate the same but I get this static image with just frame 0 shown below.

[JustinShenk]

Thanks for bringing this to my attention. The frozen screen issue is hopefully fixed in v0.2.2, along with the support for the pandas DataFrame.

Now this should work:

df = pd.DataFrame({"x":[1,10,20,5]10,"y":[2,30,40,20]10}) df.traja.animate()

Can you share a minimal amount of data so I can test it? Also via email is find (shenkjustin@gmail.com).
