I'm trying to apply multiple styles to a Google Fusion Table Layer.
This works and colors all polygons that are in an array to the blue color:
layer = new google.maps.FusionTablesLayer({
map : map,
query : {
select : "geometry",
from : "1gwSN6n_00uZ7YuAP7g4FiUiilybqDRlRmWJrpvA"
},
styles: [{
polygonOptions:
{
fillColor: "#ffffff",
strokeColor: "#bcbcbc",
fillOpacity: ".75"
}
},
{
where: whereClause,
polygonOptions: {
fillColor: "#0D58A6"
}
}
]
});
layer.setMap(map);
But this doesn't work -- no polygons even appear on my map:
layer = new google.maps.FusionTablesLayer({
map : map,
query : {
select : "geometry",
from : "1gwSN6n_00uZ7YuAP7g4FiUiilybqDRlRmWJrpvA"
},
styles: [{
polygonOptions:
{
fillColor: "#ffffff",
strokeColor: "#bcbcbc",
fillOpacity: ".75"
}
},
{
where: whereClause,
polygonOptions: {
fillColor: "#0D58A6"
}
}
,
{
where: whereClause,
polygonOptions: {
fillColor: "#ff0000"
}
}
]
});
layer.setMap(map);
Never mind that I'm coloring the same thing one color and then another--I just want the second style to work. When I take out the second style, all is fine. I put in the second style--and no polygons any more.
Can someone tell me what I'm doing wrong, please?
This may very well be an error (the exact same where clause with two different styles):
{
where: whereClause,
polygonOptions: {
fillColor: "#0D58A6"
}
}
,
{
where: whereClause,
polygonOptions: {
fillColor: "#ff0000"
}
}
I would expect the where clause to have to be unique.
UPDATE:
My current guess is that you are running into a query limit on the size of the data sent back to the server.
Each of the whereClauses works independently
If this is the issue (the query string is too big), mapping the "COUSUBFP" codes to something shorter (3 decimal digits or two hex digits), might make it work (or for that matter, just truncating the leading "0's").
03320 -> 0
03608 -> 1
etc.

I'm trying to populate a map of the U.S. in HighMaps with data from an html table. The map is showing but the data point is not. It's a latitude/longitude point. The documentation is sparse, so I'm not sure what I'm doing wrong. Here's a JSFiddle: https://jsfiddle.net/sfjeld/1wjm04fc/6/
Highcharts.mapChart('container', {
chart: {
map: 'countries/us/custom/us-all-territories'
},
series: [{
name: 'Basemap',
dataLabels: {
enabled: true,
format: '{point.name}'
}
},
{
// Specify points using lat/lon
type: 'mappoint',
data: {
table: 'pvsoiling-table',
startRow: 1,
startColumn: 1,
endColumn: 2
},
name: 'PV',
marker: {
fillColor: 'white',
lineColor: 'black',
lineWidth: 2,
radius: 10
},
color: Highcharts.getOptions().colors[1]
}
]
});
thanks,
Shauna
You can make the following changes to your code:
At the start of your <script> section, load your HTML table data into a JavaScript array:
var mapData = [];
Highcharts.data({
table: document.getElementById('pvsoiling-table'),
startColumn: 1,
endColumn: 2,
firstRowAsNames: true,
complete: function (options) {
options.series[0].data.forEach(function (p) {
mapData.push({
lat: p[0],
lon: p[1]
});
});
//console.log(mapData);
}
});
We will refer to this mapData array later on. Here is what it contains:
[
{ "lat": 33.3, "lon": -111.67 }
]
Make changes to the series section in your Highcharts.mapChart.
series: [{
name: 'Basemap',
nullColor: '#e0f9e3',
dataLabels: {
enabled: true,
format: '{point.name}'
}},
{
// Specify points using lat/lon
data: mapData,
type: 'mappoint',
name: 'PV',
marker: {
fillColor: 'white',
lineColor: 'black',
lineWidth: 1,
radius: 3
},
color: Highcharts.getOptions().colors[1]
}
]
The key part to note is the data: mapData option. The JavaScript mapData variable is the exact array that we need to represent a set of points on the map. In our case the array only contains one point - but that's because there is only one relevant row of data in the HTML table.
My map ends up looking like this:
It looks like the marker is in or near Phoenix, AZ.
Final notes:
(a) I also adjusted the marker to have lineWidth: 1 and radius: 3 (a bit smaller).
(b) I added a document ready function around everything, to ensure the DataTable is loaded before you try to read its data.
(c) There may be a more elegant way to do this, but I followed the approach in this demo. The demo actually shows how to join 2 different sets of data - not what you need. But it does show a good approach for extracting the HTML data so it can be used in the map.
Using the the Highcharts.data({...}) approach lets you access any HTML table. But since you are using DataTables, you can choose to do the following, instead. It uses the DataTables API to access each row of data:
var mapData = [];
$('#pvsoiling-table').DataTable({
"initComplete": function(settings, json) {
var api = this.api();
api.rows().data().each(function (p) {
mapData.push({ lat: Number(p[1]), lon: Number(p[2]) });
});
// your Highcharts.mapChart() logic, in a function:
buildChart();
}
});
I am using High Charts and using a Line chart for visualization. I have some bad data in the series data which is replaced with nulls and my line on the trend is not connected (bad data is not plotted on the trend, hence disconnected line) which is fine.
My issue is that I have some good data in between some bad data like (bad,bad,good,bad,bad,good,bad) this good data is shown as tool tips on my trend but no data point is shown on the trend. Is there any configuration option with in high charts so that I could plot individual data points along with disconnected line?
As you may see in the trend image, that the line series is broken but there are still some valid data points among bad data points which are not visible on the trend.
Here is how I initialize my highchart
initializeChart() {
Highcharts.setOptions({global: { useUTC : false }});
let yAxesLoc = this.getYAxes(this.props.signals);
// Update the yAxes to use the unit abbrevation instead of the full name
let dfdArr = new Array();
yAxesLoc.forEach(function(yAxis) {
if(!yAxis.unitName) {
return;
}
dfdArr.push(AfModel.GetUnitByName(yAxis.unitName, function(unit) {
if (unit) {
yAxis.unit = unit.Abbreviation;
yAxis.title = {text: unit.Abbreviation};
}
}));
});
let that = this;
// Only all the units are loaded, then we initialize Highcharts
return $.when.apply(null, dfdArr)
.always(function() {
that.yAxes = yAxesLoc; // Set all the axis
that.colorGenerator = new ColorGenerator(); // Initialize a new color generator for this trend
that.chart = Highcharts.chart(that.state.chartDivId, {
credits: {
enabled: false
},
title: null,
chart: {
zoomType:'xy',
events: {
redraw: function(){
// Remove all frozen tooltips
if (that.cloneToolTip) {
that.chart.container.firstChild.removeChild(that.cloneToolTip);
that.cloneToolTip = null;
}
if (that.cloneToolTip2) {
that.cloneToolTip2.remove();
that.cloneToolTip2 = null;
}
}
}
},
xAxis: {
type:'datetime',
min: that.props.startDateTime.getTime(),
max: that.props.endDateTime.getTime(),
labels: {
rotation: 315,
formatter: function() {
return new Date(this.value).toString('dd-MMM-yy HH:mm')
}
}
},
tooltip: {
shared: true,
crosshairs: true,
valueDecimals: 2,
formatter: function(tooltip) {
return HcUtils.interpolatedTooltipFormatter.call(this, tooltip, function(yVal, series) {
return NumberUtils.isNumber(yVal) ?
(series.yAxis.userOptions.unit) ?
NumberUtils.round(yVal, 4) + " " + series.yAxis.userOptions.unit
: NumberUtils.round(yVal, 4)
: yVal;
});
}
},
yAxis: that.yAxes,
series: {
animation: false,
marker: {enabled: false}
},
plotOptions: {

click: function() {
if (that.cloneToolTip) {
that.chart.container.firstChild.removeChild(that.cloneToolTip);
}
if (that.cloneToolTip2) {
that.cloneToolTip2.remove();
}
that.cloneToolTip = this.series.chart.tooltip.label.element.cloneNode(true);
that.chart.container.firstChild.appendChild(that.cloneToolTip);
that.cloneToolTip2 = $('.highcharts-tooltip').clone();
$(that.chart.container).append(that.cloneToolTip2);
}
}
}
}
}
});
})
}
Kindly suggest.
Thanks.
Highcharts draws a line only between two subsequent no-null points. Single points can be visualized as markers (which you disabled in your code).
Here's a live demo that shows this issue: http://jsfiddle.net/BlackLabel/khp0e8qr/
series: [{
data: [1, 2, null, 4, null, 1, 7],
marker: {
//enabled: false // uncomment to hide markers
}
}]
API reference: https://api.highcharts.com/highcharts/series.line.marker
It seems to work fine in the latest version of Highcharts. The data points are visible.
Please have a look

in my application I use angular Highstock for charts. I have a lot of data (many millions), and now i want to put the existing buttons for set date range (1week, 1 month, 3 months, 1year, all), but also to click on any button to send a new request to the server to not accumulating data. Example, if pressed button "one week", that only the server retrieves the data for one week, if you click on a button to one month, to take data for a single month. I do not want to call unnecessary data, and that the server slows down, if I'm looking for data for one month, and the server comes back to me all data. Here is the code. Thanks in advance

Thnx to #Grzegorz Blachliński i fix this. here is code
$scope.chartConfig1 = {

and here is my custom function
getDateRange = function (e) {
var date1 = new Date(e.min);
var date2 = new Date(e.max);
var timeDiff = Math.abs(date2.getTime() - date1.getTime());
var diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24));
$http.get(serviceBase + 'aaaaa/aaaaaa/' + $stateParams.klupaID + '/aaaaaaa?days=' + diffDays, function(data){
//ukoliko buden dodavat još koji config obavezno dodat broj koliko ih ima na i<=8
for (i=1; i<=8; i++){
$scope.chartConfigString = 'chartConfig' + i;
$scope.chartConfigString.series[0].setData(data);
$scope.chartConfigString.hideLoading();
}
});
};
Now i have another problems, i want to have four selectors (buttons), 1months, 3months, 1year and ALL. I set default range, when open app, on 1month, and here is problem. Buttons for another range is disabled, beacause i get data from url only for one month. I want to have enabled all buttons for select any range. Thnx
I am generating a Project Cumulative Flow Chart, which is based on the Project name that I fetch using a "find," however I can't get it working.
Here is the Problem:
1) The "Find" in my code is just fetching one kind of project name, "FE," however, I have a lot of other Project name such as FE, BE, VisualRF, etc. I am not sure what's going on
2) I return this to "storeConfig" inside the chart and then I want try to give "Name" to the "stateFieldName." This is not working! I don't see any graph at all.
Here is the code.
_chart2: function() {
var projectName = this.getContext().getProject()._refObjectName;
console.log("========");
console.log(projectName); <<<<<<<<<< This always prints one name'FE' (My project name are FE, BE, etc)
this.chart = {
xtype: 'rallychart',
storeType: 'Rally.data.lookback.SnapshotStore',
storeConfig: this._getStoreForChart2(),
calculatorType: 'Rally.example.CFDCalculator',
calculatorConfig: {
stateFieldName: this.getContext().getProject()._refObjectName, <<<<< I think usage is not fetching name of all projects
stateFieldValues: ['FE','BE','VisualRF']
},
width: 1000,
height: 600,
chartConfig: this._getChart2Config()
};
this.chartContainer.add(this.chart);
},
_getStoreForChart2: function() {
var obj1 = {
find: {
_TypeHierarchy: { '$in' : [ 'Defect' ] },
Children: null,
_ProjectHierarchy: this.getContext().getProject().ObjectID,
_ValidFrom: {'$gt': Rally.util.DateTime.toIsoString(Rally.util.DateTime.add(new Date(), 'day', -30)) },
State: "Open",
},
fetch: ['Severity','Project','ObjectID','FormattedID'],
hydrate: ['Severity','Project','ObjectID','FormattedID'],
sort: {
_ValidFrom: 1
},
context: this.getContext().getDataContext(),
limit: Infinity,
val: this.Name,
};
return obj1;
},
Though this should not matter but here is the code for the high chart function I am calling above
_getChart2Config: function() {
console.log("starting chart config");
return {
chart: {
zoomType: 'xy'
},
title: {
text: 'Chart2'
},
xAxis: {
tickmarkPlacement: 'on',
tickInterval: 20,
title: {
text: 'Date'
}
},
yAxis: [
{
title: {
text: 'Count'
}
}
],
plotOptions: {
series: {
marker: {
enabled: false
}
},
area: {
stacking: 'normal'
}
}
};
},
Down below you can see 'FE' getting printed:
Thanks a lot!

stateFieldName is the field which is used to calculate the CFD- usually ScheduleState or a custom dropdown field like KanbanState that captures your process. The stateFieldValues should be the values of that field (Defined, In-Progress, Accepted, Completed, etc.) This doesn't deal with projects at all. Definitely remember to include that field in your hydrate and fetch as well.
I am trying to color the bubbles based on the name of the cities. Something like if this.point.capital == Montgomery & this.point.capital == Juneau; color = "red". But I cannot add this if function to the color attribute. Can you help me out?
Thanks!!!!
series: [{
name: 'Basemap',
mapData: map,
borderColor: '#606060',
nullColor: 'rgba(200, 200, 200, 0.2)',
showInLegend: false
}, {
name: 'Separators',
type: 'mapline',
data: H.geojson(map, 'mapline'),
color: '#101010',
enableMouseTracking: false
}, {
type: 'mapbubble',
dataLabels: {
enabled: true,
format: '{point.capital}'
},
name: 'Cities',
data: data,
maxSize: '12%',
color: H.getOptions().colors[0]
}]

Do this for each bubble individually (not the series as a whole) in the data array prior to initiating the chart. For example extending your code (JSFiddle):
function determineColor(entry) {
if(entry.capital == "Montgomery")
return "#FF00FF";
else if(entry.capital == "Salt Lake City")
return "#00FF00";
return null;
}
// Add series with state capital bubbles
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=us-capitals.json&callback=?', function (json) {
var data = [];
$.each(json, function (ix, entry) {
entry.z = entry.population;
entry.color = determineColor(entry); // Added
data.push(entry);
});
// ... rest as usual
});
This just sets the color for each entry (which will be a bubble), as defined by the determineColor function.
