Edit height on hexbin to cumulative value.

Hi! Brand new with Kepler.gl and I am trying to get som "bar-charts" (hexbin) to increase in height as the cumulative number of sales at that location increases.

I have put the datetime to the filter and the height is set to the sales, but the animation is pretty weird and i dont quite understand what is going on. For example, one of the stores´ bar-chart stays as the same height, and some of the others decrease in height, which should obviously not happen if it sums the sales cumulative. Also, 3 charts start with a large height, and they should really start at 0 and increase eventually.

Thanks!

Start with the hexbin layer's datetime filter and sales-based height animation, using the linked GIF to compare the reported behavior. Verify how values change across time for each store; the issue is resolved when every chart starts at zero and its height reflects cumulative sales without decreasing.
