Add Points from Added Source to Mapbox Label - label

I am trying to take the data from an added layer and add it as the country-label on a stock map (in this case, Dark V 10).
Here is the code that allows me to add the data (EatPlace) from my added layer as a SEPARATE label (Works, but NOT what I want):
map.on('load', function() {
map.addSource('CEVectorSource', { //The link to your tileset
'type': 'vector',
'url': 'mapbox://xxxxx.xxxxxxxxxxxxxxxxxxx'
});
map.addLayer({
"id": "CountriesEatenNames",
"type": "symbol",
"source": "CEVectorSource",
"source-layer": "CEVectorsTileset",
"filter": ["all",["match", ["geometry-type"], ["Point"], true, false]],
"layout": {
"text-field": ['format',
['upcase', ['get', 'EatPlace']], { 'font-scale': .8 },
'\n', {},
['get', 'EatDate'], { 'font-scale': .6 }],
"text-font": ["Open Sans Semibold", "Arial Unicode MS Bold"],
"text-offset": [0, 0.6],
//"text-allow-overlap": true,
"text-variable-anchor": ['top', 'bottom', 'left', 'right']
},
"paint": {
"text-color" : 'rgb(255, 221, 153)' // Text Color
}
});
});
Here is the code that lets me modify the labels I want to modify:
map.setLayoutProperty('country-label', 'text-field',
['get', 'name_en'])
Here is what has NOT worked:
map.setLayoutProperty('country-label', 'text-field',
['get', 'EatPlace'])
I have no luck combining these concepts. Any help would be divine.

If I understand you correctly, you have a country tileset of points, a places tileset of points, and you want to display for each country point a piece of text deriving from the places tileset.
That isn't going to work. How would Mapbox-GL-JS know which country point to associate with a given place point? You will need to find some way to combine them into one layer first.

Highstock dataGrouping not working with live data

I am currently working on a project for my company, where I need to plot highstock charts, which show energy-data of our main buildings.
Since it is live data, new datapoints come per Websocket every few-or-so seconds. However, the graph should only show one datapoint every hour. I wanted to clear this with the highstock dataGrouping, but it does not really work. It groups the points yes, but it still shows the „transmission“, the graph-line, between them. Thus making the whole graph completely irreadable.
In an other Version of the project, the graph only shows the latest datapoint of each group (as specified in the „approximate“ object in the chart options), but also does not start a new group after the chosen Interval runs through.
I've been sitting on this problem for about 3 days now and have not found any proper completely working solution yet.
Unfortunately, due company policy and due to hooks and components necessary, which are only used here in the company, I'm not able to give you a jsfilddle or similar, even though I'd really love to. What I can do is give you the config, mabye you find something wrong there?
const options = {
plotOptions: {
series: {
dataGrouping: {
anchor: 'end',
approximation: function (groupData: unknown[]) {
return groupData[groupData.length - 1];
},
enabled: true,
forced: true,
units: [['second', [15]]],
},
marker: {
enabled: false,
radius: 2.5,
},
pointInterval: minutesToMilliseconds(30),
pointStart: currentWeekTraversed?.[0]?.[0],
},
},
}
This would be the plotOptions.
If you need any more information, let me know. I'll see then, what and how I can send it to you.
Thank you for helping. ^^
This is example how dataGrouping works with live data,
try to recreate your case in addition or use another demo from official Highcharts React wrapper page.
rangeSelector: {
allButtonsEnabled: true,
buttons: [{
type: 'minute',
count: 15,
text: '15S',
preserveDataGrouping: true,
dataGrouping: {
forced: true,
units: [
['second', [15]]
]
}
}, {
type: 'hour',
count: 1,
text: '1M',
preserveDataGrouping: true,
dataGrouping: {
forced: true,
units: [
['minute', [1]]
]
}
}
},

AmChart not appearing in md-dialog

I have an AmChart that I want to appear in an md-dialog. It's passed a JSON dataProvider and yet nothing appears.
dialog.tmpl.html:
<md-dialog aria-label="Project Zone Chart">
<md-toolbar>
<div class="md-toolbar-tools">
<h2>Project Zone Chart</h2>
<span flex></span>
<md-button class="md-icon-button" ng-click="closeDialog()">
<md-icon aria-label="Close dialog">close</md-icon>
</md-button>
</div>
</md-toolbar>
<md-dialog-content>
<p><div id="projZoneChart" style="width: 100%; height: auto;"></div></p>
</md-dialog-content>
</md-dialog>
controller.js:
var projZoneChartOps = {
type: "serial",
valueAxes: [{
minorGridAlpha: 0.08,
minorGridEnabled: true,
position: "top",
gridAlpha: 0,
precision: 0
}],
startDuration: 1,
graphs: [{
type: "column",
fillAlphas: 1,
lineAlpha: 0,
valueField: "value",
colorField: "color",
lineAlpha: 0
}],
rotate: true,
categoryField: "metric",
categoryAxis: {
gridPosition: "start",
parseDates: false,
gridAlpha: 0
}
};
createChart($scope.chartdata, projZoneChartOps);
function createChart(chartData, chartOps){
$scope.projZoneChart = AmCharts.makeChart("projZoneChart", chartOps);
$scope.projZoneChart.dataProvider = chartData;
However nothing appears in the dialog at all. Is there a problem with my chartOps?
Note: the chartData variable is a JSON object with two fields, startOfWeek (supposed to be the x-axis) and metric (supposed to be the y-axis)
There are a few issues/comments:
1) Why aren't you assigning the data to the chartOps object before calling makeChart?
chartOps.dataProvider = chartData;
$scope.projZoneChart = AmCharts.makeChart("projZoneChart", chartOps);
This will actually make the chart start off with your data. The way you're doing it will require that you call validateData() on your chart object after manually setting the dataProvider, which is unnecessary overhead compared to including it directly in makeChart.
$scope.projZoneChart = AmCharts.makeChart("projZoneChart", chartOps);
$scope.projZoneChart.dataProvider = chartData;
$scope.projZoneChart.validateData(); //required if you're doing it this way but unneccessary overhead compared to simply including it inside of makeChart directly as you're essentially remaking the chart after you create it for the sake of rendering your data.
2) Make sure your *field properties match. startOfWeek isn't mentioned in your chart config at all, even though you're saying it's in your JSON data. Your valueField is set to "value" - you might want to set it to "startOfWeek" instead unless you're modifying your JSON object somewhere else.
3) Displaying charts inside a modal or other dynamic/hidden elements typically require that you call the chart object's invalidateSize method when the modal/tab/etc containing the chart is visible so that it will render correctly. You'll want to check for whatever event md-dialog offers to determine when it is visible before calling $scope.projZoneChart.invalidateSize().

How to set C3JS tooltip content

I have a situation similar to the example shown in http://c3js.org/samples/data_json.html My simple intention is to get the name of the row (i.e. 'www.site1.com') into the tooltip header. My problem: I cannot find it in the d-values.
Can anyone help?
You cannot find it in d-values, because it's not a value actually - it's a category.
Have a look at Category Axis example, maybe it helps you:
var chart = c3.generate({
data: {
columns: [
['data1', 30, 200, 100, 400, 150, 250, 50, 100, 250]
]
},
axis: {
x: {
type: 'category',
categories: ['cat1', 'cat2', 'cat3', 'cat4', 'cat5', 'cat6', 'cat7', 'cat8', 'cat9']
}
}
});
I solved it by using the d-value to address the right category of my JSON, or rather the array in my JSON. (Seemed more complicated since I load the data after I create the chart.)

Coordinates are not working on ammap for USA Map

I am working on an amCharts amMap for the USA. I need to implement markers on the map. I am following this example, but it is not working as expected. The markers are not showing properly.
CODE
var map = AmCharts.makeChart("chartdiv", {
type: "map",
"theme": "light",
imagesSettings: {
rollOverColor: "#089282",
rollOverScale: 3,
selectedScale: 3,
selectedColor: "#089282",
color: "#13564e"
},
colorSteps: 10,
dataProvider: {
map: "usaLow",
images: [{
zoomLevel: 5,
scale: 0.5,
title: "Dallas",
latitude: 32.82092,
longitude: -97.0115
}, {
zoomLevel: 5,
scale: 0.5,
title: "Florida",
latitude: 25.7824,
longitude: -80.3011
}]
},
areasSettings: {
autoZoom: false,
unlistedAreasColor: "#81c5e8"
},
});
JSFIDDLE
I sympathize with the problem you are having and it is understandably confusing.
Short answer: you need to use one of the amMap USA maps that allows for latitude and longitude specifications.
Please review the answer to a similar question here:
https://stackoverflow.com/a/33772896/538962
To quote from that answer:
It seems like you are using a non-calibrated US map. ...This map is distorted for visual purposes and thus not compatible with real latitude/longitude coordinates.
To work around that, you will need to use one of the maps that are calibrated.
Here is an updated version of your example using a different USA map which does allow for specifying latitude and longitude.

KendoUI - Chart data labels

Is is possible to for the KendoUI Chart (Area) to have multiple data labels or even a concatenation of two? I need to display both a value and a percentage for each data point. Is this something that would need to be handled on the data source side or is it on the view?
Thanks for any help.
You can use templates to format both labels and tooltips; see labels.template and tooltip.template.
The key is to reference the Property you want using dataItem ex:
dataItem.TotalDollars
template: "${ category } - #= kendo.format('{0:C}', dataItem.TotalDollars)#"
The answer above wont really help unless you have a strong understanding of the Kendo UI framework. I was having a similar issue and before I found my answer I found this question. I circled back because the answer is simple and some simple example code is really simple. Lets save everyone some clicks.
