I am using agm (angular google maps) and want to draw n number of circles using ngfor but i am getting an error :
Can't bind to 'ngFor' since it isn't a known property of 'agm-circle'.
this is my html:
<agm-circle *ngFor="data in circles"
[latitude]="data.lat"
[longitude]="data.lng"
[circleDraggable]="true"
[editable]="true"
[fillColor]="'data.color'"
[radius]="data.radius"
>
</agm-circle>
this is my ts file having data:
lat: number;
lng: number;
circle: any;
#ViewChild(AgmPolygon) polygon: any;
path = [
{ lat: 51.791629704426924, lng: 7.809007 },
{ lat: 51.974729774949644, lng: 0.6317138671875 },
{ lat: 51.303145259199056, lng: 0.6646728515625 },
{ lat: 51.416338106400396, lng: -0.4779052734375 }
];
constructor () {
this.lat = 51.678418;
this.lng = 7.809007;
this.circle = [
{lat: 51.79, lng: 7.8, radius: 60000, color: 'red'},
{lat: 52.79, lng: 12.8, radius: 60000, color: 'green'},
{lat: 54.79, lng: 10.8, radius: 60000, color: 'yellow'},
{lat: 51.79, lng: 8.8, radius: 60000, color: 'yellow'},
{lat: 60.79, lng: 7.8, radius: 60000, color: 'green'},
];
}
as for as these are dummies data but this data of circles will be n any suggestion will be appreciated
i have resolved the issue by tweaking ngFor with the key-word let I dont know why AGM is not supporting the above syntax however my new:
Index.html
<agm-circle *ngFor="let data of circle"
[latitude]="data.lat"
[longitude]="data.lng"
[circleDraggable]="true"
[editable]="true"
[fillColor]="data.color"
[radius]="data.radius"
>
</agm-circle>
Hope it will be helpful :-p

I want to create a gauge diagram with amcharts 5 with persian text on it. All the code sample I found is working correctly with english text on it. But when I want to use persian or arabic text (rtl languages), it doesn't show texts correct. How can I solve this problem?
Here is my code:
<script>
var root = am5.Root.new("chartdiv");
root.setThemes([
am5themes_Animated.new(root)
]);
var chart = root.container.children.push(am5radar.RadarChart.new(root, {
panX: false,
panY: false,
startAngle: 160,
endAngle: 380
}));
var axisRenderer = am5radar.AxisRendererCircular.new(root, {
innerRadius: -40
});
axisRenderer.grid.template.setAll({
stroke: root.interfaceColors.get("background"),
visible: true,
strokeOpacity: 0.8
});
var xAxis = chart.xAxes.push(am5xy.ValueAxis.new(root, {
maxDeviation: 0,
min: -40,
max: 100,
strictMinMax: true,
renderer: axisRenderer
}));
var axisDataItem = xAxis.makeDataItem({});
var clockHand = am5radar.ClockHand.new(root, {
pinRadius: am5.percent(20),
radius: am5.percent(100),
bottomWidth: 40
})
var bullet = axisDataItem.set("bullet", am5xy.AxisBullet.new(root, {
sprite: clockHand
}));
xAxis.createAxisRange(axisDataItem);
var label = chart.radarContainer.children.push(am5.Label.new(root, {
fill: am5.color(0xffffff),
centerX: am5.percent(50),
textAlign: "center",
centerY: am5.percent(50),
fontSize: "3em"
}));
axisDataItem.set("value", 50);
bullet.get("sprite").on("rotation", function () {
var value = axisDataItem.get("value");
var text = Math.round(axisDataItem.get("value")).toString();
var fill = am5.color(0x000000);
xAxis.axisRanges.each(function (axisRange) {
if (value >= axisRange.get("value") && value <= axisRange.get("endValue")) {
fill = axisRange.get("axisFill").get("fill");
}
})
label.set("text", Math.round(value).toString());
clockHand.pin.animate({ key: "fill", to: fill, duration: 500, easing: am5.ease.out(am5.ease.cubic) })

}
else if (i === 25) {

}
}
, 100);

I also searched about it in documentation of amcharts 5 but I couldn't find the answer.
I'm using the Google Maps Javascript API, and I've defined a polygon and attached it to a map:
const region = new google.maps.Polygon({
map: map,
paths: [
{ lat: 40.5577151228437, lng: -74.15980859374997 },
{ lat: 40.599436503265856, lng: -74.27516503906247 },
{ lat: 40.67030312529891, lng: -74.25319238281247 },
{ lat: 40.72548139969253, lng: -74.26079167357881 },
],
});
I have a click handler that adds a marker on it when the user clicks:
google.maps.event.addListener(map, 'click', function (e) {
const marker = new google.maps.Marker({
map: map,
position: e.latLng,
});
});
I see the marker when I click on areas outside of the polygon, but I don't see the marker when I click inside the polygon.
I've tried hard-coding a zIndex on each, but no luck. Any ideas?
Two options:
add a click listener to the polygon
google.maps.event.addListener(region, 'click', function (e) {
const marker = new google.maps.Marker({
map: map,
position: e.latLng,
});
});

I am using google-maps for Angular, and I can't find how to change the color of the marker. I have different coordinates and I wish to color each one separately.
For now I am using :
const marker = {
position: {
lat: parseFloat(site.lat),
lng: parseFloat(site.lng),
},
icon: "https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png",
id: site.id,
title: site.address,
label: {
color: 'red',
text: site.contractCode,
}
};
I tried to pass an object with url attribute to icon, and a string, but none worked.
Thanks in advance
Can you use:
<map-marker class="markerR" #marker="mapMarker" *ngFor="let unaalerta of listado"
[position]="unaalerta.Marker"
[options]="{icon: { url:'assets/images/{{unaalerta.icono}}' }, zIndex: 100}"
I have a chart.js bar chart that pulls data via an ajax call to a Django APIView. The ajax call returns one dictionary with a stack of data inside I use to customize the chart. Here's the chart.js code:
var current_year = '{% url "saveskore:api-current-year-savings" %}'
$.ajax({
url: current_year,
type: 'GET',
cache: false,
dataType: 'json',
success: function(data) {
var ctx = document.getElementById('current-year-chart');
var chart = new Chart(ctx, {
type: 'bar',
data: {
labels: data['dates'],
datasets: [
{
label: data['income_label'],
backgroundColor: "#8e5ea2",
data: data['income'],
},
{
label: data['expense_label'],
backgroundColor: 'green',
data: data['expenses'],
},
{
label: data['savings_label'],
backgroundColor: "#3e95cd",
data: data['savings_goal'],
},
{
label: data['avail_label'],
backgroundColor: "#pink",
data: data['avail_to_spend'],
},
]
},
options: {
legend: { display: false },
title: {
display: true,
text: 'Savings for ' + data['year']
}
}
});
}
});
Works great. Looks great.
But! I have a django formset on a separate page that updates the table data that the chart pulls from.
When I update the data in the formset and submit, redirecting to the chart page ... NO UPDATE OCCURS.
If I make some code change or otherwise reload the browser, VOILA, the chart updates.
I have read about either cache=false and chart.update(), but find i have not been able to make either work, mainly because the exact details on their use are not clear.
I would really appreciate input on this.
Have you tried chart.destroy() method ? and then build again the chart with the new data .. that works for me.. take a look at my example
let flag = 0;
var xChart = "";
function dibujar(valor, meses) {
try {
if (valor.length > 0) {
$('#grafico').fadeIn('fast');
var canvas = document.getElementById('chart');
let tipGra = $('#slcTipGra').val();
if (flag !== 0) {
xChart.destroy();
}
//rgba(54, 162, 235, 0.2)
if (tipGra === "bar" || tipGra === "horizontalBar") {
var data = {
labels: meses,
datasets: [
{
label: "Dólares($)",
backgroundColor: "#3e95cd",
borderColor: "#3e95cd",
borderWidth: 2,
hoverBackgroundColor: "#3e95cd",
hoverBorderColor: "#3e95cd",
data: valor,
}
]
};
var option = {
title: {
display: true,
fontSize: 20,
fontFamily: 'Helvetica',
text: 'Reporte Mensual de Ventas'
},
plugins: {
datalabels: {
color: 'white',
anchor: 'end',
align: 'start',
font:
{

}
}
},
scales: {
yAxes: [{
stacked: true,
gridLines:
{
display: true,
color: "rgba(255,99,132,0.2)"
}
}],
xAxes: [{
gridLines: {
display: true
}
}]
}
};
}
if (tipGra === 'line') {
var data = {
labels: meses,
datasets: [
{
label: "Dólares($)",
fill: false,
lineTension: 0.1,
backgroundColor: "rgba(75,192,192,0.4)",
borderColor: "rgba(75,192,192,1)",
borderCapStyle: 'butt',
borderDash: [],
borderDashOffset: 0.0,
borderJoinStyle: 'miter',
pointBorderColor: "rgba(75,192,192,1)",
pointBackgroundColor: "#fff",
pointBorderWidth: 1,
pointHoverRadius: 5,
pointHoverBackgroundColor: "rgba(75,192,192,1)",
pointHoverBorderColor: "rgba(220,220,220,1)",
pointHoverBorderWidth: 2,
pointRadius: 5,
pointHitRadius: 10,
data: valor,
}
]
};
var option = {
title: {
display: true,
fontSize: 20,
fontFamily: 'Helvetica',
text: 'Reporte Mensual de Ventas'
},
plugins: {
datalabels: {
backgroundColor: function (context) {
return context.dataset.borderColor;
},
borderRadius: 4,
color: 'white',
anchor: 'end',
align: 'end',
}
},
showLines: true
};
}
xChart = new Chart(canvas,
{
type: tipGra,
data: data,
options: option
});
flag = 1;
}
else {
$('#grafico').fadeOut('fast');
$('#graficoMessage').fadeIn('slow');
}
} catch (err) {
console.log(err);
}
}
I declare "xChart" as a global variable and a flag to know if it's the first chart to build. The example build 3 different types of charts (Vertical Bar, Horizontal Bar and Line) depending on the selection of the chart type "let tipGra = "$('#slcTipGra').val();"
How can I create scroll when I drag jsplumb connections to the top of the browser?
I searched through the net but couldn't find a solution to create scrolls.
