So essentially I am working with a large dataset and don't want to have to define every area for every year. But when I update to the next year it only appends the data to the map leaving the rest there to be shown in the legend.
I tried using replaceOptions and it just turns the map gray and it becomes unresponsive.
There has to be something easy I am overlooking.
It also seems to not be working entirely correct when I update the year. As some I click on a county to show that data and it will give me a javascript error of: main.js.php:85 Uncaught TypeError: Cannot read property 'value' of undefined
Even though the data is in the object. I have it set to console log and can search for what it should display and it's there.
Any help would be appreciated. You can check out the project here. It is for a nonprofit.
Thanks
