instead of using event.offsetX and event.offsetY, just chenge it to event.clientX and event.clientY

You'll have to find the sweet spot for your transform-origin because of your image, see below. Also unless the rotating image is symmetrical you'll always get that little wobble you see in the example so might want to tweak that also. Cheers.

Ok looks like I overcomplicated things. As @Bergi pointed out the following was more usefull: instead of refering to the values i now just do a loop over the relevant properties

It's pretty hard to do this in raw SQL, without built in windowing functions; data step SAS will have some better solutions.

Some of this depends on your data size. One example, below, does exactly what you ask for, but it probably will be impractical with your real data. Some of that is the 31DEC9999 dates - that makes for a lot of data - but even without that, this has thousands of rows per person, so if you have a million people or something this will get rather large. But, it might still be the best solution, depending on what you need - it does give you the absolute best control.

If you just need to make the swing visible during the animation, the easiest solution is simply apply overflow: visible to the element.

Edit: If you want to center the , the best solution I recommend would be using display: flex and justify-content: center on the wrapper

Here's a working example:

Simply use steps() then control the duration:

The formulas in the Mathematics Stack Exchange answer that you're using to derive the coefficients of the power series expansion of F are based on complex analysis - coming for example from Cauchy's residue theorem (though other derivations are possible). One of the assumptions necessary to make those formulas work is that you have a holomorphic (i.e., complex differentiable) function.

Your definition of F gives a function that's not holomorphic. (For one thing, it always gives a real result for any complex input, which isn't possible for a non-constant holomorphic function.) But it's easily fixed to be holomorphic, while continuing to return the same result for real inputs.

Here's a fixed version of F, which replaces x.real with x. Since the input to exp is now complex, it's also necessary to use cmath.exp instead of math.exp to avoid a TypeError:

You need to use the $input.json method instead of $input.path.

You need to check is.na and you can take advantage of the fact that NA & FALSE resolves to FALSE and TRUE | NA resolves to TRUE.

Try this:
