Highchart plotLines z Index between series z Index - javascript

I am trying to create a fiddle, mocking up the image attached
in following jsfiddle
http://jsfiddle.net/2TuCW/162/
The problem is I want the plotLines between blue line and green column.
I tried changing the zIndexes of plotLines (10) , between blue line (15) and green column (5) in following fiddle
http://jsfiddle.net/2TuCW/163/
//plotLines zIndex
"plotLines" : [
{
"color": '#E5E7EB',
"zIndex": 10,
"width": 2,
"value": 20
},
....
....
//Series data z-index
"series": [{
"type":"column",
"data": [35,39,49,50,57,58],
"zIndex":5
....
....
"series": [{
"type":"line",
"data": [35,39,49,50,57,58],
"zIndex":15
But it is not working as expected. Please suggest how to achieve it.

It is related with fact that all series have the same zIndex.

Try to adjust the values of the plotLines.
If you want a plot line to be between blue line and green column the value of the plotLines has to be between the data of blue line and data of column.

Unfortunately, it seems that plotLines can either be in front of all series or behind all series. This is because all series are grouped under a common element. A plotLine element is a sibling to the group element, not a sibling to the individual series elements.

This issue relates to the fact that all series are drawn within the same group, and therefore have the same z-index related to other groups. A related GitHub issue has discussion and code examples.
See this one example solution, proposed by Torstein Hønsi (Highcharts creator). I've made a modified, minimal, reproducible example here:
/**
* Plugin to allow plot band Z indexes in between series
*/
Highcharts.wrap(Highcharts.PlotLineOrBand.prototype, 'render', function (proceed) {
var chart = this.axis.chart;
proceed.call(this);
if (!chart.seriesGroup) {
chart.seriesGroup = chart.renderer.g('series-group')
.attr({ zIndex: 3 })
.add();
}
if (this.svgElem.parentGroup !== chart.seriesGroup) {
this.svgElem
.attr({ zIndex: this.options.zIndex })
.add(chart.seriesGroup);
}
return this;
});
Highcharts.chart('container', {
xAxis: {
plotLines: [{
color: 'red',
width: 2,
value: 3.5,
zIndex: 10
}]
},
series: [{
data: [7988, 12169, 15112, 22452, 34400, 34227],
zIndex: 9
}, {
data: [8105, 11248, 8989, 11816, 18274, 18111],
zIndex: 11
}]
});
The code uses Torsteins plugin to allow the plotline in between series. See the GitHub issues for discussion on caveats and potential improvements.

How to create legend for Plotlines with Highstock of Highcharts?

I have a Highstock graph with Plotlines here: http://jsfiddle.net/qd0rmazg/3/
I'd like to be able to have a legend of Plotlines where, similar to the legend of Series, upon a click Plotlines of a certain category can be made visible or hidden.
In my JSfiddle example, there are 2 categories of Plotlines. Is it possible to toggle the visibility of Plotlines per one category? I couldn't seem to find anything supporting this.
This is how I've created the Plotlines:
xAxis: {
plotLines: [{
value: Date.UTC(2016, 12, 29), // year, month, day
width: 1,
color: 'blue',
dashStyle: 'ShortDash',
label: {
text: 'Category 1',
},
}, {
value: Date.UTC(2016, 11, 12), // year, month, day
width: 1,
color: 'green',
dashStyle: 'Solid',
label: {
text: 'Category 2',
}]
}
As far as I know, there is no native HC legend for the plot lines. But, you can create your custom legend element on the page and use HC capabilities to show/hide plot lines as in their examples:
http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/members/axis-addplotline/
chart.xAxis[0].removePlotLine('plot-line-1');
chart.xAxis[0].addPlotLine({
....
id: 'plot-line-1'
});
As noted in my comment, there is a feature request here:
https://highcharts.uservoice.com/forums/55896-highcharts-javascript-api/suggestions/3009547-plotlines-on-legend
Please add your votes and comments.
Vladimir M provided a good solution to show/hide the plot lines with your own custom legend.
The other common approach is to use a line series as your plotLine, which gives you the benefit of the full series functionality.
Example series:
{
name: 'PlotLine',
type: 'line',
color: 'rgba(204,0,0,1)',
data: [25,25,25,25,25,25,25,25,25,25]
}
Fiddle:
http://jsfiddle.net/jlbriggs/nh65m306/
If you need a vertical plot line, the data set up is slightly more complex but still quite feasible.
{{EDIT to demo vertical plot line:
First, you;d have to set a min/max for you y axis (could be done programmatically on chart load):
yAxis: {
min: 0,
max: 75,
maxPadding: 0
}
Then, you specify your data in [x,y] pairs, with the x values being your plotLine value, and the y values being your Y axis min and max:
data: [[4,0], [4,75]]
Updated fiddle:
http://jsfiddle.net/jlbriggs/nh65m306/1/
With that method, you could add a series per plot line, or, if you want all of them to be the same legend and settings, you can add multiple by inserting null points between your desired lines:
data: [[4,0], [4,75], [5,null], [7,0],[7,75]]

Format X axis interval in the Chart - Kendo UI

I have the following code which display the line on the chart. I could not able to find how to format the x axis. I would like to show every thousand interval similar to y axis (0,1000,2000,3000,4000, etc). I am using Kendo UI.
function createChart() {
$("#chart").kendoChart({
title: {
text: "Units sold"
},
dataSource: {
data: stats
},
categoryAxis: {
labels: {
step: 1000,
format: "n0"
},
},
series: [{
type: "area",
line: {
style: "smooth"
},
field: "x",
categoryField: "y"
}],
});
}
Here is my fiddle:
http://jsfiddle.net/nDS3S/37/
If I get right, your code doesn't works because the step doesn't really mean that would be shown a label for each 1000, but in fact it will show a label for each serie. So your chart doesn't have 1000 series, that is why only 0 was displayed.
If you change your step to 5, you will see the labels, but displaying the exactly number for that specific serie.
Check this out.
I'm afraid you can't achieve what you want.

flot jquery is it possible to draw this kind of chart

I used to draw this kind of chart (one vertical axis, one horizantal axis):
Now i have been asked to do this kind of chart:
as you see, the problem with the ordered chart that it contains (two vertical axis, one horizantal axis).
My question
does flot or any other jquery library able to do that please?
See the flot example here on multiple axis. Minimal example:
$.plot("#placeholder", [
{ data: d1 },
{ data: d2, yaxis: 2 } // set second series to use second axis
], {
yaxes: [ {
min: 0 // options for first axis
}, {
alignTicksWithAxis: 1 // options for second axis, put it on right
position: "right"
} ],
});
Two mix a bar and line chart set that in each's series object:
$.plot("#placeholder", [{
data: d1,
lines: { show: true }
}, {
data: d2,
bars: { show: true }
}]);
Putting these together, here's an example:

Highcharts multiple x-Axis without multiple series?

This fiddle uses multiple series and displays an axis for each of them. Is it possible to use a single series to make several Axes? http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/combo-multi-axes/
xAxis:[{
categories:setup.x_mixed,
maxZoom:5,
minPadding: 0.2,
labels:{
"enabled":setup.categories_label,
"y":1,
"style":{
"fontSize":13,
"color":"#999",
fontFamily:"'helvetica neue',helvetica",
whiteSpace:"nowrap",
textOverflow:"clip",
width:"100%",
marginTop:legendSpacing
},
formatter:function () {
return this.value.split("|")[0]
}
},
lineColor:"rgba(255,255,255,0)",
tickWidth:0,
offset:0
}, { // Secondary yAxis
categories:setup.x_mixed,
maxZoom:5,
minPadding: 0.2,
labels:{
"enabled":setup.categories_label,
"y":16,
"style":{
"fontSize":13,
"color":"#999",
fontFamily:"'helvetica neue',helvetica",
whiteSpace:"nowrap",
textOverflow:"clip",
width:"100%",
marginTop:legendSpacing
},
formatter:function () {
return this.value.split("|")[1]
}
},
lineColor:"rgba(255,255,255,0)",
tickWidth:0,
offset:0
}],
You can also use linkedTo paramtetr on extra axis http://api.highcharts.com/highcharts#yAxis.linkedTo
its pretty simple,
declare 2 xAxis same like the yAxis you mentioned in the example with one of them as
opposite:true
As you have only one series set the second axis extremes same as the first one using getExtremes() and setExtremes(), as shown in this fiddle here http://jsfiddle.net/W43Zb/
Hope this will help you

Tick and label for every xAxis Unit in Highcharts Chart

I have a chart like the one in this fiddle: http://jsfiddle.net/h9Bqj/
As shown in the image there is no tick for "3" and "5" on the xAxis as well as no label. I am not able to figure out how to show a tick for every xAxis.
The [...]
xAxis: {
labels: {
step: 1
},
tickInterval: 1
}
options did not work for me.
How would I get a tick and a label for every increment?
Set tickInterval as 1, as you have, and add pointInterval as 1.
http://api.highcharts.com/highcharts#plotOptions.series.pointInterval
http://jsfiddle.net/h9Bqj/1/
Actually I figured it out by myself.
Setting pointRange via plotOptions: {
column: {
stacking: 'normal',
pointRange: 1
}
}, in the options or in the series does the trick.
See: http://jsfiddle.net/DZbyp/1/
