I have a chart that allows the user to select an option to compare to a statewide average. The chart works fine until I use the stringify method to create annotations - the number of columns varies based on the selection. What is your advice on how to retain this functionality, and still have data labels?

Here is the stringify method I was using, but it messes up the above code:
//
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, { calc: "stringify",
sourceColumn: 1,
type: "string",
role: "annotation"},
2,{ calc: "stringify",
sourceColumn: 2,
type: "string",
role: "annotation" }]);
//
It could be that I'm doing this all wrong - advice, appreciated. This type of coding is new to me.
I've got it working now with set columns, but the dropdown to change the value no longer works. My guess is that once the graph shifts into DataView (rather than DataTable), it becomes "read-only" and the interactivity is lost. (This example is using another chart.) I need a way of redrawing the table when another option is selected.

I have a map of geojson facility points located in Alaska. I want to allow the user to switch between a regular and satellite view. Upon clicking satellite, the loaded geojson data disappears.
I have tried reinstatiating the code, but I realize I do not know how to do that properly. Otherwise, im not sure what the solution is.
I have a working plunker here

Hoping that when you click satellite, the new view enters as well as the geojson.
I am using Uikit (getuikit.com) and google charts but the tooltips in the chart do not show when using uk-sortable="handle: .uk-sortable-handle".
I have done a jsfiddle so you can see it is not working at the moment.
It works if I take out the link for the uikit.css(but I need it this one).
Also it works if I remove the uk-sortable="handle: .uk-sortable-handle" from the div(but I also need this one to make the tile draggable) the tooltips come back, so I know it is something to do with uikit. Have anyone found a work around this?
Thank you for your help.

Here is the jsfiddle
https://jsfiddle.net/justme0112/kqaLmvgu/1/
I expect the tooltips to work with uikit.
I found the solution, you just need to comment line 6055 from uikit.css
.uk-sortable svg {
pointer-events: none;
}
That was making the hover not appear on the google chart.

Actually when I look at the result in a browser I see the javascript above the
<div id = "right"> whereas I would like to have the javascript at the left and the <div id = "right"> at the right.
Here is my css :
#Global
{
width:100%;
}
#Global #left {
float:left;
width:60%;
}
#Global #right {
margin-left:60%
}
I thought It will work but it is not the case.
Thank you for your help !
This is why I get when I look at the result in a browser :
Another option, aside from the ones already provided, would be to make your Global div a table instead and your left and right divs can be sibling cells in a row on that table.
Here is my HTML and JS. I have tried putting the padding on both bottomWrapper and topList, but for some reason neither seems to work for padding-right. The other styles seem to be fine. Nothing is floated or anything that I know of. Any ideas? This is a WebView for Android, but really shouldn't matter in this case I get the same behavior when I just render this code in a browser.

toolTipContent: "{y} - <strong>#percent%</strong>",
dataPoints: [
{ label: "Stat1", y: 30, color: "#5877F5", exploded: true, legendText: "30%" },
{ label: "Stat2", y: 70, color: "#EB483F", legendText: "70%" }

});
chart.render();
}
I solved the problem like this:
<script type="text/javascript">
window.onload = LoadChart;
</script>
HTML:
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
<script type="text/javascript" src="Scripts\Chart.js"></script>
<script type="text/javascript" src="\Scripts\canvasjs.min.js"></script>
<script type="text/javascript">
window.onload = LoadChart;
</script>
</head>
<body>
<div>
<div id="chartContainer" style="height: 300px; width: 300px; margin-left:auto; margin-right:auto;"></div>
</div>
</body>
</html>
JS:
function LoadChart() {
var chart = new CanvasJS.Chart("chartContainer", {
theme: "theme2",//theme1
title: {
text: "Stats"
},
legend: {
verticalAlign: "bottom",
horizontalAlign: "center"
},
data: [
{
// Change type to "bar", "splineArea", "area", "spline", "pie",etc.
indexLabelFontSize: 20,
indexLabelFontFamily: "Monospace",
indexLabelFontColor: "darkgrey",
indexLabelLineColor: "darkgrey",
indexLabelPlacement: "outside",
type: "pie",
showInLegend: true,

}
]
});
chart.render();
