ApexCharts day-label on xaxis is showing inconsistently - javascript

I'm using ApexCharts to display a rangeBar. If I slide the rangeBar from side to side, the date on the xaxis is showing inconsistently. For instance on this image, I have two days - the 26th and the 27th, but the day label is hidden.
If I zoom out and zoom in, the day-label is showing.
I've been looking at ApexCharts docs several times, and have tried many different things to enforce this day label to always show, but without any luck.
Here is my configuration
var options = {
series: [
{
data: arr
}
],
colors: [
"#00be00",
],
chart: {
height: 150,
width: '100%',
type: 'rangeBar',
toolbar: {
tools: {
download: false,
// pan: false,
},
},
},
plotOptions: {
bar: {
horizontal: true
}
},
xaxis: {
type: 'datetime',
},
};
Can I somehow force the day-label to always show?

How to display single data-values with ApexCharts correctly?

I am currently trying to build a barchart with ApexCharts. Everything works fine when the data-array has more than one entry. Somehow, whenever data only contains one element, the diagram messes up the width of the bar.
Correct state with multiple entries:
Buggy state with one entry
My goal is to display a single value with the same xaxis scale and the same barwitdh as the barchart displays multiple values.
I already tried using an array of timestamps for each hour as catigories-prop but this didn't work for me.
I use 'dateime' as type for my xaxis.
Data is an array that can contain 0, 1 or x entries. It is given to the Barchart-Component as data-prop.
Categories contains a the timestamp to each entry of data. Therefore it can also have 0, 1, or x values. Categories is used as the Barcharts categories-prop.
Here are my configurations (For the buggy state):
var options = {
series: [
{
name: "Servings",
data: [[1669082400000, 44]]
}
],
chart: {
height: 350,
type: "bar",
animations: {
enabled: false
},
zoom: {
enabled: false
}
},
dataLabels: {
enabled: false
},
xaxis: {
type: 'datetime',
labels: {
datetimeUTC: false,
datetimeFormatter: {
year: 'yyyy',
month: 'MMM',
day: 'dd',
hour: 'HH:mm'
}
},
categories: [
1669082400000,
],
min: 1669075200000,
max: 1669161600000
},
tooltip: {
intersect: false,
shared: true
},
yaxis: {
reversed: false,
}
};
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
Would be nice if somebody could help me out, I'm tripping over this one.

How to get values from all the charts in the tooltip you are currently hovering

I am using Highcharts in the vue.js environment. I use https://www.highcharts.com 7.2.0 and Highcharts-Vue https://github.com/highcharts/highcharts-vue#readme 1.3.5.
I have multiple highstock charts in the same page. I am trying to get the values from all the charts into the tooltip of the highstock that I am currently hovering.
Based on this http://jsfiddle.net/mjsdnngq/14/ I am trying to create my code
This is what I have now
vue template
<template>
<div class="vessChart" v-on:mousemove="updateCoordinates" >
<v-card :loading=!this.getStreamPlots.done>
<highcharts ref="chart" :constructor-type="'stockChart'" :callback="chartcallback" :options="options" ></highcharts>
</v-card>
</div>
</template>
This is the "options" as I define it for the chart as a vue data object
options: {
tooltip: {
shared: true,
pointFormat: '{series.name}: {point.y}<br>'
},
chart: {
type: "line",
zoomType: 'x'
},
title: {
text: this.streamChart.title
},
rangeSelector: {
inputEnabled: false
},
xAxis: {
ordinal: false,
type: 'datetime',
tickInterval: 5 * 60 * 1000 ,
labels: {
enabled:false
},
events : {
afterSetExtremes : this.afterSetExtremes
}
},
yAxis: {
title: {
text: this.streamChart.title
},
labels: {
enabled:true
},
alignTicks:'left',
textAlign:'left',
align:'middle',
opposite:false
},
plotOptions: {
series: {
animation: false
}
},
responsive: {
rules: [{
condition: {
maxWidth: 500
},
chartOptions: {
chart: {
height: 300
},
subtitle: {
text: null
},
navigator: {
enabled: false
},
legend: {
enabled: true
},
yAxis: {
title: {
enabled: false
}
}
}
}]
},
series: [
{
name: this.streamChart.title,
pointStart: 1546300800000,
pointInterval: 5 * 60 * 1000
}
]
},
when the Highstock loads, I use callback, to get it and set it as a local vue var and also push it in an array in the vuex store, so I can have all charts available.
chartcallback(hc){
this.chart=hc;
this.currentId = this.streamChart.id;
this.chartData = this.chartData.concat(this.getStreamPlots[this.currentId].data);
this.addStreamCharts(hc); //push it to an array in vuex store
this.chart.series[0].setData(this.chartData, true, true, true);
},
and then I use the updateCoordinates to get all the values from all the charts I saved in vuex store, using the searchPoint. Then, feed the values to the tooltip of the chart I am currently hovering
updateCoordinates(e){
if (this.getStreamPlots.done && this.chart != null) {
let hce = this.chart.pointer.normalize(e);
let points=[];
this.getStreamCharts.forEach(chart => {
let point = chart.series[0].searchPoint(hce, true);
points.push(point);
});
this.chart.tooltip.refresh(points);
}
}
Problems :
1- This works but it shows all the values to the first chart I hovered. For example, I hover to the first chart, I get all the values into the tooltip as I should. But then I hover to the third chart and the values are still showed in the first chart tooltip. No tooltip in the third chart.
2- The values are in different tooltips. I would like for all the values be in one tooltip. (check the image)
Thank you

jQuery Flot xaxis elements number

Im trying to generate graph with jquery Flot.
This is the script Im using:
var plot = $.plot("#placeholder", [
{ data: data2, label: observation_obj.concept_name}
], {

lines: {
show: true
},
points: {
show: true
}
},
grid: {
hoverable: true,
clickable: true
},
yaxis: {
},
xaxis: {
mode: "time",
timeformat: "%d.%m"
}
});
The result I'm getting is this:
http://i62.tinypic.com/25uk51z.png
My data is contains of two points, I dont know why in the x axis I see 4 points,
Can anyone help?
Thanks
The ticks on the x-axis are automatically generated so that they are evenly spaced on the axis. If you want to change that you can give flot an array of (in your case) timestamps which match the timestamps from your data (only examples here):
xaxis: {
mode: "time",
timeformat: "%d.%m",
ticks: [1383582043000, 1383682043000]
}
See the documentation for more infos / examples.

Highstock Column Chart - data grouping causes data to scroll independently of axis

I am attempting to make a stacked column chart representing events on a timeline. I need evenly-spaced bars, that scroll left/right with their respective ticks. Currently upon scrolling, the columns remain in place and their data is updated to reflect the new timespan they represent (I assume).
For example: when scrolling one "step" to the right, I note these differences:
The column remains in place with updated data and the axis tick moves to the left. This results in a 'graphic equalizer'-like effect when scrolling. (See fiddle)
What I need is to have the column represent the same data for the life of the chart, and to scroll left/right with its tick mark.
I suspect I'm misunderstanding something in the configuration. Any help/direction would be very much appreciated.
(As a side note: is there any easy way to style/color data from the past (with an xAxis datetime value of < today) differently to normal data?)
chart: {
alignTicks: false,
backgroundColor: '#eeeeee',
events: {
load: function (e) {
this.xAxis[0].setExtremes(1390943153305, 1400015153305);
}
},
ignoreHiddenSeries: true,
renderTo: $('#chart')[0]
},
colors: ['#89f1a4','#68d9f7','#9eb9ef','#c49eef'],
credits: {enabled: false},
legend: {
enabled: true,
shadow: true
},
rangeSelector: {selected: 1},
title: {text: 'Global Events'},
navigator: {
height: 40,
xAxis: {
gridLineWidth: 1
},
series: {type: 'column'}
},
plotOptions: {
series: {
showInLegend: true,
stacking: 'normal',
dataGrouping: {
enabled: true,
forced: true,
units: [
['millisecond', [604800000]], // Attempting to force data into weekly groups, throws error if this is null
['second', [604800]],
['minute', [10080]],
['hour', [168]],
['day', [7]],
['week', [1]], // Expected this to be the only required option if I only want weekly grouping...
['month', null],
['year', null]
]
}
}
},
xAxis: {ordinal: false},
series: data
If you want just weekly grouping, then only that one set, see: http://jsfiddle.net/s6BmC/2/
I think that resolves your issue, right?
plotOptions: {
series: {
showInLegend: true,
stacking: 'normal',
dataGrouping: {
enabled: true,
forced: true,
units: [ [ 'week', [1] ]]
}
}
},
Regarding additional question:
- yes you can set specific color for each point, but you need to determine on your own what color should be set:
data: [{ x: timestamp, y: value, color: color }, { x: timestamp, y: value, color: color }... ]
Another solution is to wrap setting color for column. Something similar I have done for candlestick: http://jsfiddle.net/79WZM/ (this solution requires much more knowledge of Highcharts).

Disable hover on HighCharts

I have building a pie chart using HighCharts library, and here is my chart:
// http://jsfiddle.net/t2MxW/20890/
var chart = new Highcharts.Chart({
colors: ['#0072BC', '#BFDAFF', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4'],
credits: { enabled: false },
chart: {
renderTo: 'container',
backgroundColor: 'rgba(255, 255, 255, 0.1)',
type: 'pie',
margin: [0, 0, 0, 0],
spacingTop: 0,
spacingBottom: 0,
spacingLeft: 0,
spacingRight: 0
},
title: { text: null },
plotOptions: {
pie: {
allowPointSelect: false,
size: '100%',
dataLabels: { enabled: false }
}
},
series: [{
showInLegend: false,
type: 'pie',
name: 'Pie Chart',
data: [
['Mobile', 65], // first half of pie
['Other', 35] // second half of pie
]
}]
});
But the problem is that I don't want appearing tooltip on mouse over...
Is it possible to disable tooltip on hover?
Disabling tooltip just disables the tooltip but the hover effect is still present. To disable the hover effect, add the following to your plotOptions:
plotOptions: {
series: {
states: {
hover: {
enabled: false
}
}
}
},
You need to set the tooltip attribute to false, like so:
tooltip: { enabled: false },
jsFiddle here
Here's the full code for your case:
var chart = new Highcharts.Chart({
colors: ['#0072BC', '#BFDAFF', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4'],
credits: { enabled: false },
tooltip: { enabled: false },
chart: {
renderTo: 'container',
backgroundColor: 'rgba(255, 255, 255, 0.1)',
type: 'pie',
margin: [0, 0, 0, 0],
spacingTop: 0,
spacingBottom: 0,
spacingLeft: 0,
spacingRight: 0
},
title: { text: null },
plotOptions: {
pie: {
allowPointSelect: false,
size: '100%',
dataLabels: { enabled: false }
}
},
series: [{
showInLegend: false,
type: 'pie',
name: 'Pie Chart',
data: [
['Mobile', 65], // first half of pie
['Other', 35] // second half of pie
]
}]
});
You might alternatively want to disable all mouse tracking in general, both tooltip and hover effects:
(copy and paste link) http://api.highcharts.com/highcharts#series.enableMouseTracking
http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/plotoptions/series-enablemousetracking-false/
plotOptions: {
series: {
enableMouseTracking: false
}
}
The title of the question is about disabling hovering, so in case anyone else finds themselves here for that purpose, I'll elaborate on #SergeyB's answer.
There are a few options that affect how mouse hovering changes a series' styling. They each have different effects depending on the series type. I'll talk about line and pie series here, but generally, you can look under plotOptions.<seriesType>.states.hover for styling applied to the currently hovered series and plotOptions.<seriesType>.states.inactive for styling applied to the non-hovered series (e.g. plotOptions.pie.states.hover). None of these options affect the tooltip styling.
plotOptions.series.states.inactive
plotOptions.series.states.inactive affects the styling applied to all series that aren't currently being hovered over. To prevent them from fading into the background, set plotOptions.series.states.inactive.opacity to 1.
var chartOptions = {
// ...
plotOptions: {
series: {
states: {
inactive: {
opacity: 1,
},
},
},
},
}
jsFiddle for line
jsFiddle for pie
plotOptions.series.states.hover
plotOptions.series.states.hover affects the styling applied to the series that's being hovered over. For example, for a line series, the default is to thicken the line width and apply a halo to the nearest point.
To disable any styling of a currently hovered line series, set plotOptions.series.states.hover.enabled to false.
var chartOptions = {
// ...
chart: {
type: "line",
},
plotOptions: {
series: {
states: {
hover: {
enabled: false,
},
},
},
},
}
jsFiddle
Unfortunately, if we set this on a pie series, this will make the hovered slice fade into the background with the rest of the inactive slices (see this jsFiddle for an example). If we want to remove all hover styling without affecting the inactive styling, we can set plotOptions.series.states.hover.halo.size to 0 (which removes the halo) and plotOptions.pie.states.hover.brightness to 0 (which removes the brightening effect). Note that since brightness is specific to pie series, it's documented under plotOptions.pie instead of plotOptions.series (though it worked for me even when I added it under plotOptions.series).
var chartOptions = {
// ...
chart: {
type: "pie",
},
plotOptions: {
series: {
states: {
hover: {
halo: {
size: 0,
},
// this worked for me even though it's not
// documented under plotOptions.series:
//brightness: 0,
},
},
},
pie: {
states: {
hover: {
brightness: 0,
},
},
},
},
}
jsFiddle
plotOptions.series.stickyTracking
If you're using a line or area series, you may have noticed that as soon as you hover over the chart, even if you're not touching a series, the nearest series will receive hover styling and the rest will receive inactive styling. This is because plotOptions.series.stickyTracking is true by default for line and area series. If you set plotOptions.series.stickyTracking to false, hover and inactive styling will only be applied while you're hovering over a line.
var chartOptions = {
// ...
chart: {
type: "line",
},
plotOptions: {
series: {
stickyTracking: false,
},
},
}
jsFiddle
plotOptions.series.enableMouseTracking
As #ninedozen noted, you can completely disable all responsive interactions based on mouse movement by setting plotOptions.series.enableMouseTracking to false. Note that this will also disable tooltips in addition to hover/inactive styling.
Options scope
To apply these options to all series in the entire chart, place them under plotOptions.series. To apply them only to certain series types (or if the option is specific to a certain series), place them under plotOptions.<seriesType>. To apply them to a specific series, place them inside that series' options.
var chartOptions = {
series: [
{
name: "series1",
type: "line",
data: [...],
// these options will only apply to series1, not series2 or series3
states: {...},
},
{
name: "series2",
type: "line"
data: [...],
},
{
name: "series3",
type: "pie"
data: [...],
}
],
plotOptions: {
// these options will apply to all series in the chart
series: {states: {...}},
// these options will only apply to series of type line
// i.e. series1 and series2
line: {states: {...}}
}
}
You can simply turn them of using the following:
tooltip: {
enabled: false
},
plotOptions: {
series: {
states: {
inactive: {
opacity: 1,
},
},
}
}
I did this to display multiple line charts on hover.
In order to completely turn off tooltip and hover effects on a chart,
it is needed to turn off the tooltip, disable hover state and set inactive data opacity to 100%.
This answer is based on previous answers and shows a complete solution to the problem.
This is the configuration which turns off the hover and tooltip effects:
series: {
states: {
hover: {
enabled: false
},
inactive: {
opacity: 1,
}
}
},
tooltip: {
enabled: false
}
you can simply disable it by setting the option
tooltip:{
enabled: false
}
I usually just disable the style in css so I can still access the hover event in JS if needed...
.highcharts-tooltip {
display: none;
}
As specified in the accepted answer, you need to set
tooltip: { enabled: false }
Note - you must specify this as a property of your Highcharts.Options object (i.e. your chart options object, not a property of your series). So, either specify it in the JSON that you pass into your Highcharts.Chart object, or specify it as a property of a Highcharts.Options object that you explicitly create, before you pass it to you Highcharts.Chart
See https://api.highcharts.com/highcharts/tooltip.enabled
