Will do. May not be for a few days as I'm away from my laptop until next week.

@knolleary,
I will help with what I know. It has been a learning experience for us all.

This is going to require some wizardry help from someone who lives in a grotto on top of a mountain. lol

Hey Seth (@seth350),
Just for completeness, in case anybody needs a unique id per widget instance.
In the [code](https://github.com/bartbutenaers/node-red-contrib-ui-heatmap/blob/master/heat_map.js) of the node-red-contrib-ui-heatmap node, I simply append the **node id** :
```auto
function HTML(config) {
return String.raw``;
```
And then you can get a reference to that element anywhere in your code, by appending the node id:
```auto
var uniqueElement = document.getElementById('someNotUniqueId' + $scope.config.id);
```
