We have a chart that plots multiple series at once.
There are the main y-series (line type) that will have the main data readings.
There is the option to set two different 'levels' (line types) on the y-axis as well.
There are also options to have multiple additional y-axis bars (bar types).
With the x-axis being the datetime
Here is what a typical example of a chart looks like with valid date for the given range
This is working as expected.
We have the main y-series as the average air temp (left y-axis)
Then we have two bars, one for rainfall and one for irrigation (right y-axis)
And then the two 'levels', one red and one blue.
This is all great.
However, when we go to a date range in the future, where there is no air temp data, we get the following
Note that the start date is 2 days before the date range, and the end date looks equal distance from the end of the 'levels'
Interestingly if we remove the bars we get the following
This now shows the 'levels' to span the full width of the chart
If we remove the lines and just have the bars then we get the following (which is how it should look, but with the 'levels')
There seems to be something in here that is causing the conflict when there are multiple y-series without the main y-series.
I am setting the xAxis.setExtremes to the start and end dates of the date range we are looking at, but that seems to be doing nothing.
Here is the config;

I am at a bit of a loss here as to why this is happening.
Can anyone shed some light on this?
One of the solutions can be to add additional x-axis and bind line series to it. Then it looks like your expected result. Check demo and code posted below.

There are three data series, two of them are bar type series (Insolation Duration and Power Duration).
When I import data (from Striped Table) to the Highcharts, the bar chart height doesn't display properly.
It doesn't fit the scale of the chart's value, like this:
e.g. 2018/05/01
The Insolation value is less than the Power value, but the height of Power Duration bar chart is higher than Insolation Duration.
Here are the chart options I use:
var ChartObj =
{
type: "chart",
value:
{
"chart": { "alignTicks": false, "zoomType": "xy" },
"title": { "text": " ", "floating": false, "align": "center" },

"backgroundColor": "#FFFFFF"
},
"yAxis":
[
{
"gridLineColor": "transparent",

{

},

}
]
}
};
You will need to set a max to the 2 first column axis like this
{
"gridLineColor": "transparent",
"labels":
{
"format": "{value}",
"style": { "color": "#7cb5ec" },
"enabled": false
},
"title": { "text": null, "style": { "color": "#7cb5ec" } },
"opposite": false,
"index": 0,
max:12 // The value to set
},
Or change the index of your series to use the same yAxis

I'm trying to display a chart as a single, horizontal column with a vertical legend below it. Here's what I have so far:
Highcharts.chart('container', {
"legend": {
"itemMarginBottom": 10
},
"responsive": {
"rules": [
{
"condition": {
"maxWidth": 700
},
"chartOptions": {
"legend": {
"layout": "vertical"
}
}
}
]
},
"chart": {
"type": "bar",
"margin": [
0,
0,
44,
0
]
},
"credits": false,
"plotOptions": {
"bar": {
"dataLabels": {
"enabled": true,
formatter() {
let value = this.y * 100;
return value > 4 ? `${ value.toFixed(1) }%` : null;
},
"overflow": "none"
},
"groupPadding": 0,
"pointPadding": 0
},
"series": {
"animation": false,
"pointPadding": 0,
"pointWidth": 40,
"stacking": "percent",
"events": {},
"marker": {
"states": {
"hover": {
"enabled": false
},
"select": {
"enabled": false
}
}
}
}
},
"series": [
{
"name": "Optimized",
"data": [
0.7455639561796032
],
"zIndex": 0
},
{
"name": "Partially Optimized",
"data": [
0.1260607930874859
],
"zIndex": -1
},
{
"name": "Not Optimized",
"data": [
0.064033328190094
],
"zIndex": -2
},
{
"name": "Plant Off",
"data": [
0.06434192254281708
],
"zIndex": -3
},
{
"name": "Communication Failure",
"data": [
0
],
"zIndex": -4
}
],
"title": false,
"tooltip": false,
"xAxis": {
"labels": false,
"maxPadding": 0,
"minPadding": 0
},
"yAxis": {
"endOnTick": false,
"labels": false,
"maxPadding": 0,
"min": 0,
"minPadding": 0,
"reversedStacks": false,
"title": false
}
});
And this is what it looks like:
The chart is responsive, and I'd really like to avoid setting a hardcoded height for the whole chart. Rather, I'd like for the plot height of the chart to be 40px, and for Highcharts to size the height of the chart to include the remaining room for the chart's legend.
Ideally, it would look like this:
Here's a link to the JSFiddle.
You can change height of xAxis and yAxis to 40px and on each redraw event calculate optimal height for chart (top margin + height of the yAxis + bottom margin). Take a look at the example below.

I'm trying to set a secondary axis with a min/max value, and the primary axis often overwrites the max on the secondary axis.
I know that I could use alignTicks:false, but I don't like the way that makes the ticks look. I also know that I can hide the ticks for one of the axes, but again, I don't like they it looks.
I would like to either force the right side to use min/max and figure out the proper tick intervals, or I'd like to force the left side to have a specific number of ticks.
I need some ideas, here's a jsfiddle with my code and some mock data.

$('#container').highcharts({

You could try setting your tickInterval to 10 in your y-axis definition:
"tickInterval": 10

I am trying to display to my users the number of videos recorded per day with each one of their cameras. To do so I would like to use a stacked back (each stack showing the # of videos recorded with a given camera). Here are the options I am passing in:

The graph displays the data correctly but is rendering the columns extremely narrowly even when there are only 2 days of data (image below). Is there a way for me to deine the scale of the x-axis so the widths of the columns will display a bit better?

You can set pointWidth and startOnTick / endOfTick
