Bars Overlap Each Other During Animation #23

Closed andresberejnoi closed 4 years ago

andresberejnoi commented 4 years ago

Hello, I have been trying this library to animate data I collected about my puppies while they were growing. However, I have a problem where many of the bars overlap with each other.

The dataset has 9 different dogs, and about 200 data points per dog (there are many NaN values in between). Do you have any suggestions about what could be the issue?

Could it be the NaN values messing with the code?

Try using df.fillna(method='ffill') and df.fillna(method='bfill') or interpolation ; whichever works best for your case.

Hi Andres, I haven't really tested data with lots of missing values and as @kuharan mentioned, its best to fill them in before doing the race. Can you attach the dataset here in a separate post (or link to it)? Thanks!

Thanks. I tested by just filling all missing values with interpolation and the problem was solved. I will close this issue. I have another question about using images for lables, but I think I will open a separate issue for that.
