Map coloring values incorrect.

I was trying out some of the map values and got data that doesn't seem to match:

I look for "Percentile" values such as "Percentile Cancer Risk" and some of the areas have values over 99.
Similarly, I looked for "Pct" values such as "Pct. Minority Population" and I got values over 1.

You can see these as the darker color ones in the view. I think we may be manipulating the data in some incorrect way and/or sorting it strangely.

Oh and I checked in the table view and the values don't have the range in there, so it's just the "Data Value" that I get when I mouseover. I don't know if the map coloring is correct or not, but the mouseover value is incorrect.

So currently we're calculating the value in each tract (clickable area) by summing all the values of locations in that tract. This works for a lot of values like the concentration of minerals or the total number of something, but not for percentile.
How would we handle this case? I think we may need to process data in different ways for different sets too...

1. Adding a note here about some areas showing up as black despite there being data.
2. We shouldn't have to sum any longer because the Gardenroots data should already be anonymized, so I think we should just show the smaller area (e.g., block group) rather than the tract. Then we won't have to sum at all, just show the data.

Thanks!

3. There seems to be an overlapping range issue with the chosen colors, where sometimes an area with a higher value has a lighter color than one with a lesser value. See the two screenshots of "Total Population" below. The upper left selection has ~10,000 and is a middle color but the lower dark area has the darkest color but only ~6,000 (@jwwood3 found this).

@TT1603 Reminder now that you're back on the project :)
