My goal is to display two small Highchart line charts (height:100px;) inside of a Mapbox pop-up. I have two divs inside the HTML to hold the charts, which as is shown in the image below appear to take the charts because the axes are showing up just fine.
The thing that is perplexing me is that the series and markers are not displaying, save for half of the first marker that is split by the y-axis. When inspecting the Highchart element in Chrome, all paths for the markers and series appear to be in the right location and are marked as visibility="visible".
Has anyone run into a similar issue?

I am trying to make a gradient line chart, The issue is with tooltip legend color and color of data points, they appear in brown gradient which was the default.
I was able to change the tooltip color, anyhow that is not the actual data point color but able to fix it to one color at least. whereas the points on the line do not pick up the color of the line.
Can someone point me in right direction?

You need to add gradientColor array to echarts options. Now echart will take care of changing color of tooltip and data point. You can also remove your custom tooltip formatted function.
gradientColor: ["#00d4ff", "#090979"]
Here the complete options object:
var data = [];
var dateList = data.map(function(item) {
return item[0];
});
var valueList = data.map(function(item) {
return item[1];
});
option = {
gradientColor: ["#00d4ff", "#090979"],
// Make gradient line here
visualMap: [
{
show: true,
type: "continuous",
seriesIndex: 0,
min: 0,
max: 400
}
],
title: [
{
left: "center",
text: "Gradient along the y axis"
}
],
xAxis: [
{
data: dateList,
axisPointer: {
label: {
color: ["#5470c6"]
}
},
axisLabel: {
formatter: function(value) {
return moment(value).format("MMM YY");
// And other formatter tool (e.g. moment) can be used here.
}
}
}
],

I'm quite new here (and to web development in general), so please forgive any misuses that I perpetuate... I'm trying to create a basic windrose plot with data returned (in JSON) from the MesoWest Mesonet API service. I'm using HighCharts (or attempting to), and cannot quite get it to work. Perhaps this is due to my methodology of obtaining the data from the API itself as I'm a complete amateur in this regard. The following is the Javascript code, followed by the HTML for the page. Could someone please take a look and let me know what I've done wrong? Nothing displays on the page when I attempt to load it. In addition, if you're curious as to the specifics of an API call for MesoWest, like the one I've employed here, please see http://mesowest.org/api/docs/
The .js script:
var windrose = {
divname: "windrosediv",
tkn: "eecfc0259e2946a68f41080021724419",
load:function()
{
console.log('loading')
if (!window.jQuery) {
var script = document.createElement("script");
script.src = 'https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js';
script.type = 'text/javascript';
document.getElementByTagName("head")[0].appendChild(script);
setTimeout(pollJQuery, 100)
return
}
this.div = $("#"+this.divname);
this.request('WBB');
},
pollJQuery:function()
{
if (!window.jQuery) {
setTimeout(pollJQuery,100);
} else {
load();
}
},
request:function(stn){
console.log("making a request")
$.getJSON(http://api.mesowest.net/v2/stations/nearesttime?callback=?',
{
stid:stn,
within:1440,
units:'english',
token:windrose.tkn
}, this.receive);
},
receive:function (data)
{
console.log(data,windrose);
stn = data.STATION[0]
dat = stn.OBSERVATIONS
spd += Math.round(dat.wind_speed_value_1.value)
dir += dat.wind_direction_value_1.value
windDataJSON = [];
for (i = 0; i < dir.length; i++) {
windDataJSON.push([ dir[i], spd[i]
]);
},
}
$(function () {
var categories = ['0', '45', '90', '135', '180', '225', '270', '315'];
$('#container').highcharts({
series: [{
data: windDataJSON
}],
chart: {
polar: true,
type: 'column'
},
title: {
text: 'Wind Rose'
},
pane: {
size: '85%'
},
legend: {
align: 'right',
verticalAlign: 'top',
y: 100,
layout: 'vertical'
},
xAxis: {
min: 0,
max: 360,
type: "",
tickInterval: 22.5,
tickmarkPlacement: 'on',
labels: {
formatter: function () {
return categories[this.value / 22.5] + '°';
}
}
},
yAxis: {
min: 0,
endOnTick: false,
showLastLabel: true,
title: {
text: 'Frequency (%)'
},
labels: {
formatter: function () {
return this.value + '%';
}
},
reversedStacks: false
},
tooltip: {
valueSuffix: '%'
},
plotOptions: {
series: {
stacking: 'normal',
shadow: false,
groupPadding: 0,
pointPlacement: 'on'
}
}
});
});
And the HTML:
<!DOCTYPE html>

I appreciate any guidance in this regard, thanks!!!

#W.Howard, I think the problem here is how you are treating and preparing the JSON response from the API. Consider the following JavaScript to retrieve and parse out the data:
/*
* Helper function
* scalarMultiply(array, scalar)
*/
function scalarMultiply(arr, scalar) {
for (var i = 0; i < arr.length; i++) {
arr[i] = arr[i] * scalar;
}
return arr;
}
/*
* getQuery(station, api_token)
*/
function getQuery(station, mins, api_token) {
$.getJSON('http://api.mesowest.net/v2/stations/timeseries?callback=?', {
/* Specify the request parameters here */
stid: station,
recent: mins, /* How many mins you want */
obtimezone: "local",
vars: "wind_speed,wind_direction,wind_gust",
jsonformat: 2, /* for diagnostics */
token: api_token
},
function(data) {
try {
windSpeed = data.STATION[0].OBSERVATIONS.wind_speed_set_1;
windDir = data.STATION[0].OBSERVATIONS.wind_direction_set_1;
windGust = data.STATION[0].OBSERVATIONS.wind_gust_set_1;
} catch (err) {
console.log("Data is invalid. Check your API query");
console.log(this.url);
exit();
}
/* Convert from knots to mph */
windSpeed = scalarMultiply(windSpeed, 1.15078);
//windGust = scalarMultiply(windGust, 1.15078);
/* Create and populate array for plotting */
windData = [];
for (i = 0; i < windSpeed.length; i++) {
windData.push([windDir[i], windSpeed[i]]);
}
/* Debug */
// console.log(windData);
console.log(this.url);
plotWindRose(windData, mins);
})
};
What we had now is an 2D array with wind direction and wind speed that we can pass to the plotting function. Below is the updated plotting function:
/*
* Plot the wind rose
* plotWindRose([direction, speed])
*/
function plotWindRose(windData, mins) {
/*
* Note:
* Because of the nature of the data we will accept the HighCharts Error #15.
* --> Highcharts Error #15 (Highcharts expects data to be sorted).
* This only results in a performance issue.
*/
var categories = ["0", "45", "90", "135", "180", "225", "270", "315"];
$('#wind-rose').highcharts({
series: [{
name: "Wind Speed",
color: '#cc3000',
data: windData
}],
chart: {
type: 'column',
polar: true
},
title: {
text: 'Wind Direction vs. Frequency (Last ' + mins/60. + ' hours)'
},
pane: {

legend: {

verticalAlign: 'top',
y: 100,

tickInterval: 45,
tickmarkPlacement: 'on',
labels: {
formatter: function() {
return categories[this.value / 45] + '\u00B0';
}
}
},
yAxis: {

endOnTick: false,
showLastLabel: true,

I'm trying to create a bar chart using C3 and D3 but I'm having trouble getting the columns to be unrelated to each other, other than for the fact that they use the same scale on the Y-axis.
I've included images to better explain.
var chart = c3.generate({
bindto: '#designerChart',
data: {
columns: [
['MA', 6],
['ME', 8],
['NY', 6],
['CN', 5],
['TX', 2]
],
type: 'bar',
},
axis: {
y: {
max: 10,
min: 0,
padding: { top: 0, bottom: 0 }
}
}
});
Results in a group of bars and when I hover over them I get the details for all the bars - not what I want.
I can change the data, so that it displays separate columns, but they are the same color and when I want to transition it to a pie chart you can't distinguish between the states.
var chart = c3.generate({
bindto: '#designerChart',
data: {
x: 'x',
columns: [
['x','MA', 'ME', 'NY', 'CN', 'TX'],
['rainfall', 6, 8, 6, 5, 4 ]
],
type: 'bar',
},
axis: {
x: {
type: 'category'
},
y: {
max: 10,
min: 0,
padding: { top: 0, bottom: 0 }
}
}
});
This is what I want:

Colors turn to original in this fiddle (Full Page). But it changes colors as aspected on working local files , and local references of c3 , d3 ,and jquery.

How to resolve the issue?. If you see the pop-up dialog it is not displaying the same "export enabled" boolean value.
Adding min and minRange to your exporting.chartOptions.xAxis seems to yield positive results. This does require max to still be there, and seemingly it gives varying results if any of those three are missing.
For example (updated JSFiddle):
exporting:{
enabled: true,
sourceWidth: 960,
sourceHeight: 400,
chartOptions: {
xAxis: [{
categories: categories,
min: 0, // Added for fix
minRange: categories.length-1, // Added for fix
max: categories.length-1
}],
scrollbar:{
enabled: false
}
}
}
Hopefully this resolves your issue. As to why, I do not know.
If only one record in data then pie chart not display. I'm using Flot chart.
<script type='text/javascript'>
$(function () {
var data = [{
label: "Series1",
data: 1
}, ];
$.plot($("#graph11"), data, {
series: {
pie: {
show: true,
radius: 1,
tilt: 0.5,
label: {
show: true,
radius: 1,
formatter: function (label, series) {
return '<div style="font-size:8pt;text-align:center;padding:2px;color:white;">' + label + '<br/>' + Math.round(series.percent) + '%</div>';
},
background: {
opacity: 0.8
}
},
combine: {
color: '#999',
threshold: 0.1
}
}
},
legend: {
show: false
}
});
});
</script>
When only one record in data then pie chart not display.
Code looks fine.
Except
If you are running this in older versions of IE (<=7):
var data = [{
label: "Series1",
data: 1
}, ]; // <--remove the trailing comma
It'll die on the trailing comma.
