I am using Birt line chart where I want to achieve something like this How to format series labels of a BIRT chart by script
I want to show the points which are below marker line in red color just like this link has mentioned.
Modify fillColor of marker.
Code Snippet:
beforeGeneration: function(options)
{
var throughTargetPercent = this.getReportVariable("through_target_percent");
for(var i = 0 ; i < options.series.length ; i++){
var data = options.series[i].data;
var len = data.length;
for (var j=0; j < len; j++){
if(data[j].y < throughTargetPercent) {
data[j]= {
y: data[j].y,
marker: {
fillColor: "yellow"
}
}
}
}
}
},
Hope it helps!

I am trying to do a loop into a loop and a get the Cannot red property 'getText' of undefined error.
Here is my code:
element.all(by.className('col-md-4 ng-scope')).then(function(content) {
element.all(by.className('chart-small-titles dashboard-alignment ng-binding'))
.then(function(items) {
for(var i = 0; i<=content.length; i++) {
items[i].getText().then(function(text) {
expect(text).toBe(arrayTitle[i]);
});
}
});
element.all(by.className('mf-btn-invisible col-md-12 ng-scope'))
.then(function(itemsText) {
for(var i=0; i<=content.length; i++) {
for(var x = 0; x<=arrayContent.length; x++) {
itemsText[i].getText().then(function(textContent) {
expect(textContent).toBe(arrayContent[x]);
});
}
}
});
});
I am using the .then in the .getText() so i don't know what happens.
Your main problem now is you wrote 30 lines of code and you debug all of them at once. There maybe 1000 on possible issues. For this reason noone will help you, because I don't want to waste my time and make blind guesses myself. But if you reorgonize your code so you can debug them 1 by 1 line, then every line may have only a few issues.
With that said, stop using callbacks, I can see you don't completely understand what they do. Instead start using async/await. See how easy it is... Your code from question will look like this
// define elementFinders
let content = element.all(by.className('col-md-4 ng-scope'));
let items = element.all(by.className('chart-small-titles dashboard-alignment ng-binding'));
let itemsText = element.all(by.className('mf-btn-invisible col-md-12 ng-scope'));
// get element quantity
let contentCount = await content.count();
let itemsTextCount = await itemsText.count();
// iterate
for(var i = 0; i<contentCount; i++) {
// get text
let text = await items.get(i).getText();
// assert
expect(text).toBe(arrayTitle[i]);
}
// iterate
for(var i=0; i<contentCount; i++) {
for(var x = 0; x<itemsTextCount; x++) {
// get text
let text = await itemsText.get(i).getText();
// assert
expect(text).toBe(arrayContent[x]);
}
}
This way you can console.log any variable and see where your code breaks
let's say I have 4 columns (series) of data I need to display as lines.
value,series1,series2,series3,series4
V1,0,10,4,12
V2,8,13,15,10
V3,5,10,5,12
V4,12,7,8,12
V5,10,10,2,12
Echarts graph as lines
Is there an option to set in one sentence all settings for all series ?
the manual way is, for example:
xAxis: {type:'category'},
series:[{type:'line'},{type:'line'},{type:'line'},{type:'line'}],
... and I'm loooking for a simple way to set:
all series: {type:'line'}
The only way to achieve that is doing something like that:
var data = [
[V1,0,10,4,12],
[V2,8,13,15,10],
[V3,5,10,5,12],
[V4,12,7,8,12],
[V5,10,10,2,12]
];
var defaultSeries = [];
for (var i = 0; i < data.length; i++) {
defaultSeries.push({ type: 'line' });
}
var option = {
xAxis: {type:'category'},
series: defaultSeries,
}
myChart.setOption(option);
Hi I have connection between marker with polyline like this Image .
I am attaching a sample here.
How Can I make drag possible that when I drag the the marker with polyline.
example , If I drag the marker 3 it should also update the polyline point and where ever I put the marker 3 polyline should connect with marker 3.
I need this type of drag event that can update the polyline also when dragging the marker.
I am using leaflet for this purpose but still unable to solve the dragging logic of marker with polyline.
Here is the sample code I am using
$http.get("db/getConnectionData.php").then(function (response) {
$scope.links1 = response.data.records;
// $scope.showArrow();
angular.forEach($scope.links1, function(value, i) {
var source_panoId = $scope.links1[i].s_panoId;
var dest_panoId = $scope.links1[i].d_panoId;
var sPanoID = $scope.links1[i].sourcePano_id;
var dPpanoID = $scope.links1[i].destPano_id;
angular.forEach($scope.panoramas, function(value, index) {
if($scope.panoramas[index].panoId == source_panoId){
if($scope.links.indexOf($scope.panoramas[index])== -1){
$scope.links.push($scope.panoramas[index]);
}
var SlatLang = $scope.panoramas[index].project_latLng ;
var SLatLngArr = SlatLang.split(",");
var Slat = parseFloat(SLatLngArr[0]);
var Slang = parseFloat(SLatLngArr[1]);
var polypoint1 = [Slat, Slang];
angular.forEach($scope.panoramas, function(value, index1) {
if($scope.panoramas[index1].panoId == dest_panoId){
if($scope.links.indexOf($scope.panoramas[index1])== -1){
$scope.links.push($scope.panoramas[index1]);
}
var DlatLang = $scope.panoramas[index1].project_latLng ;
var DLatLngArr = DlatLang.split(",");
var Dlat = parseFloat(DLatLngArr[0]);
var Dlang = parseFloat(DLatLngArr[1]);
var polypoint2 = [Dlat, Dlang];
// Draw seperate polyline for each connection
polyline = L.polyline([[Slat, Slang],[Dlat, Dlang]],
{
color: 'blue',
weight: 5,
opacity: .7,
}
).addTo(map);
$scope.polycoords.push(polyline);
}
});
}
});
Here is the code that I am using to make drag of marker with polyline
angular.forEach($scope.panoramas, function(value, index4){
$scope.markers[index4].on('dragstart', function(e){
var latlngs = polyline.getLatLngs(),
latlng = $scope.markers[index4].getLatLng();
for (var i = 0; i < latlngs.length; i++) {
if (latlng.equals(latlngs[i])) {
this.polylineLatlng = i;
}
}
});//dragstart
$scope.markers[index4].on('drag', function(e){
var latlngs = polyline.getLatLngs(),
latlng = $scope.markers[index4].getLatLng();
latlngs.splice(this.polylineLatlng, 1, latlng);
polyline.setLatLngs(latlngs);
});//drag
$scope.markers[index4].on('dragend', function(e){
delete this.polylineLatlng;
});//dragEnd
});
First, when creating the marker, remember to pass the draggable option as true, like this:
var marker = L.marker(latLng, { draggable: true });
Now, check which drag event you want to attach a listener to and then call the redraw function of the polyline inside the callback, like this:
// var polyline defined somewhere
marker.on('drag', function (e) {
polyline.redraw();
});
If this doesn't work, please provide sample code so we can work around with it.
Edit
You also need to change the coordinates of the polyline, otherwise redraw will do nothing. Check out this answer on SO and see if it fits your needs.
Edit 2
You're using an array of polylines while the answer just uses one polyline which has the array of coordinates, so in your case you need to use two loops to accomplish the same task. You can make this faster and maybe use an object as a lookup table to get the right polyline for each marker, for example, like this:
var table = {};
// ...
table[marker] = polyline;
Then later you can get the polyline used for each marker. But anyway, here's what I think would work in your case the way it is in the sample (it was a little hard to understand but I hope it works for you).
I don't know where you are putting the second part of your sample (the event handlers) but I assume it's not inside the double loop that is creating the polylines, right? So this is what I came up with:
marker.on('dragstart', function (e) {
var markerLatLng = marker.getLatLng();
this.polylineLatLngs = [];
for (var i = 0; i < $scope.polycoords.length; i++) {
var polyline = $scope.polycoords[i];
var latLngs = polyline.getLatLngs()
for (var j = 0; j < latLngs.length; j++) {
if (markerLatLng.equals(latLngs[j])) {
this.polylineLatLngs.push([i, j]);
}
}
}
});
marker.on('drag', function (e) {
for (var i = 0; i < this.polylineLatLngs.length; i++) {
var polyline = $scope.polycoords[this.polylineLatLngs[i][0]];
var latLngs = polyline.getLatLngs();
var markerLatLng = marker.getLatLng();
latLngs.splice(this.polylineLatLngs[i][1], 1, markerLatLng);
polyline.setLatLngs(latLngs);
}
});
I am getting this type of behavior. Please let me know how I can solve this .
Thank you for your time.
This is the polyline created by getting data from db or by making the connection between panorama.
This Image when I start dragging the marker 2 I got the result like this
This image when I dragged the marker 3.
This type of result I am getting using the source code you provided above.
I few days ago I implement a routingControl = L.Routing.control({...}) which works perfect for my needs. However I need for one of my customer also the RouteBoxer which I was also able to implement it. Now following my code I wants to remove the boxes from my map in order to draw new ones. However after 2 days trying to find a solution I've given up.
wideroad is a param that comes from a dropdown list 10,20,30 km etc.
function routeBoxer(wideroad) {
this.route = [];
this.waypoints = []; //Array for drawBoxes
this.wideroad = parseInt(wideroad); //Distance in km
this.routeArray = routingControl.getWaypoints();
for (var i=0; i<routeArray.length; i++) {
waypoints.push(routeArray[i].latLng.lng + ',' + routeArray[i].latLng.lat);
}
this.route = loadRoute(waypoints, this.drawRoute);
}; //End routeBoxer()
drawroute = function (route) {
route = new L.Polyline(L.PolylineUtil.decode(route)); // OSRM polyline decoding
boxes = L.RouteBoxer.box(route, this.wideroad);
var bounds = new L.LatLngBounds([]);
for (var i = 0; i < boxes.length; i++) {
**L.rectangle(boxes[i], {color: "#ff7800", weight: 1}).addTo(this.map);**
bounds.extend(boxes[i]);
}
console.log('drawRoute:',boxes);
this.map.fitBounds(bounds);
return route;
}; //End drawRoute()
loadRoute = function (waypoints) {
var url = '//router.project-osrm.org/route/v1/driving/';
var _this = this;
url += waypoints.join(';');
var jqxhr = $.ajax({
url: url,
data: {
overview: 'full',
steps: false,
//compression: false,
alternatives: false
},
dataType: 'json'
})
.done(function(data) {
_this.drawRoute(data.routes[0].geometry);
//console.log("loadRoute.done:",data);
})
.fail(function(data) {
//console.log("loadRoute.fail:",data);
});
}; //End loadRoute()
Well, my problem is now how to remove previously drawn boxes in order to draw new ones because of changing the wideroad using a dropdown list. Most of this code I got from the leaflet-routeboxer application.
Thanks in advance for your help...
You have to keep a reference to the rectangles so you can manipulate them (remove them) later. Note that neither Leaflet nor Leaflet-routeboxer will do this for you.
e.g.:
if (this._currentlyDisplayedRectangles) {
for (var i = 0; i < this._currentlyDisplayedRectangles.length; i++) {
this._currentlyDisplayedRectangles[i].remove();
}
} else {
this._currentlyDisplayedRectangles = [];
}
for (var i = 0; i < boxes.length; i++) {
var displayedRectangle = L.rectangle(boxes[i], {color: "#ff7800", weight: 1}).addTo(this.map);
bounds.extend(boxes[i]);
this._currentlyDisplayedRectangles.push(displayedRectangle);
}
If you don't store a reference to the L.rectangle() instance, you obviously won't be able to manipulate it later. This applies to other Leaflet layers as well - not storing explicit references to Leaflet layers is a usual pattern in Leaflet examples.
I have a leaflet map and I am using the Leaflet.markerCluster plugin to cluster my markers. I have some markers that represent multiple points on the same location. Unfortunately when it gets clustered it only represents one single point. Is there a way to add a weight to each marker? So that the cluster sees it as more than one point?
Basically I am hoping for a clusterWeight property like the follwing:
var newMarker = L.marker(coordinates, {
icon: myIcon,
clusterWeight: 5
});
This propety does not exist however. Anyoneknow of a work around? Thanks!
First you will need to create a marker that supports custom properties. You can do this by extending the default L.Marker like so:
var weightMarker = L.Marker.extend({
options: {
customWeight: 0
}
});
Then you can make use of Leaflet.markercluster's iconCreateFunction to create a custom cluster marker, by changing what is displayed on the marker:
var markers = L.markerClusterGroup({
iconCreateFunction: function(cluster) {
// iterate all markers and count
var markers = cluster.getAllChildMarkers();
var weight = 0;
for (var i = 0; i < markers.length; i++) {
if(markers[i].options.hasOwnProperty("customWeight")){
weight += markers[i].options.customWeight;
}
}
var c = ' marker-cluster-';
if (weight < 10) {
c += 'small';
} else if (weight < 100) {
c += 'medium';
} else {
c += 'large';
}
// create the icon with the "weight" count, instead of marker count
return L.divIcon({
html: '<div><span>' + weight + '</span></div>',
className: 'marker-cluster' + c, iconSize: new L.Point(40, 40)
});
}
});
