Render line chart across the plotting area - highcharts

Highcharts line chart, how to render across plot area.
Trying to render the line chart using HighCharts library to span across the entire plotting area. Using xAxis.min was able to make sure the start is from 0 on xAxis, however, not able to figure out how to make it end where chart plot area ends.

Instead of using dates as x-axis categories you can add a date to point x property and define x-axis type = "datetime". Check the demo posted below.
Code:
"xAxis": {
"type": "datetime",
...
},
"series": [{
...
"data": [{
"y": 396,
"x": new Date('2019-06-10').getTime(),
"toolTipData": "<div>Times on Air : 396</div><br/>"
},
{
"y": 468,
"x": new Date('2019-06-17').getTime(),
"toolTipData": "<div>Times on Air : 468</div><br/>"
}
]
}]
Demos:
With categories, tickInterval, and tickPositions.
Without them.

Make minPointLenght apply to all blocks in stacked column chart

We're using minPointLength property to make points with a value of 0 show up in a stacked column chart. The problem is that now a point with a value of 4 (third column from left in screenshot) is displayed smaller than the minimum height. In the following screenshot the very tiny block with value 4 is hovered and the blocks with 0 are displayed in red.
I expected that blocks with a value bigger than 0 are also bigger than the blocks with a value of 0 or at least same height.
Our overall target is to set a minimum height for all blocks, in a way that all the box labels can be shown.
Here is a fiddle to play around: https://jsfiddle.net/ftmkxdbo/
This is the configuration of our chart:
Highcharts.chart('container', {
"chart": {
"type": "column"
},
"title": {
"text": ""
},
"credits": {
"enabled": false
},
"xAxis": {
"categories": ["10/17", "10/18", "10/19", "10/20"]
},
"yAxis": {
"title": {
"text": ""
},
"stackLabels": {
"enabled": true,
"style": {
"color": "gray"
}
},
"min": 0,
},
"legend": {
"enabled": false
},
"plotOptions": {
"column": {
"stacking": "normal",
"dataLabels": {
"enabled": true,
"style": {
"fontSize": "10px",
"fontWeight": "normal",
"textShadow": "0px"
},
},
"minPointLength": 5,
}
},
"series": [{
"name": "3",
"data": [{
"x": 0,
"y": 3,
}],
"index": 0,
"color": "rgba(120,185,40,0.8)"
}, {
"name": "12",
"data": [{
"x": 0,
"y": 12,
}],
"index": 1,
"color": "rgba(245,155,0,0.8)"
}, {
"name": "19",
"data": [{
"x": 0,
"y": 19,
}],
"index": 2,
"color": "rgba(120,185,40,0.8)"
}, {
"name": "13",
"data": [{
"x": 0,
"y": 13,
}],
"index": 3,
"color": "rgba(120,185,40,0.8)"
}, {
"name": "18",
"data": [{
"x": 1,
"y": 18,
}],
"index": 0,
"color": "rgba(120,185,40,0.8)"
},
// ...
]
});
That is a very problematic issue. Currently the columns overlap because the stacking functionality does not take into account the minPointLength option. If it were otherwise, the total value of the column would be incorrect.
You can see all discussion about this problem on github: https://github.com/highcharts/highcharts/issues/1776

Highcharts xAxis has extra gap when multiple yAxis

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;

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.

Bar chart with wrong bar height

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" },

},
"yAxis":

{

{

{
"format": "{value}",
"style": { "color": "#f7a35c" },
"enabled": false
},
"title": { "text": null,
"style": { "color": "#f7a35c" } },
"opposite": true,
"index": 2,
}
],
"series":
[
{
// Insolation
"name": " ",
"color": "#90ed7d",
"tooltip":
{
"valueSuffix": "",
"pointFormat": "<span style=\"color:{point.color}\">●</span> {series.name}: <b>{point.y:,.2f}</sup></b><br/>"
},
"yAxis": 0,
"type": "column",
"data": [],
"_symbolIndex": 0
},
{
// Power
"name": " ",
"color": "#f7a35c",

{

},
"yAxis": 2,
"type": "line",
"data": []
}
]
}
};
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

Using highcharts x-axis "zones" for datetime series chart

I've got a two-series Highcharts column chart that I'm trying to modify the color between past and future. I'd like the colors in past to be green, and colors in future to be blue essentially. I've read about highcharts "zones" which allow you to change attributes on the axis after a point, but the documentation uses a simple data chart, and not a datetime version like I'm using.
How can I use these zones with a datetime chart, or better-- how can I change the border/fill color of my bars for future instead of default colors used.

How do I force highcharts to pay attention to min and max on my secondary axis?

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.

$(function () {
$('#container').highcharts({
"title": {
"text": ""
},
"subtitle": {
"text": ""
},
"xAxis": {
"type": "datetime",
"dateTimeLabelFormats": {
"day": "%b %e"
}
},
"yAxis": [{
"min": 0,
"startOnTick": false,
"labels": {
"style": {
"color": "#4074C3"
}
},
"title": {
"text": "Revenue",
"style": {
"color": "#4074C3"
},
"margin": 5
},
"index": 0
}, {
"allowDecimals": false,
"min": 0,
"max": 100,
"maxPadding": 0.2,
"startOnTick": false,
"labels": {
"style": {
"color": "#8DAD36"
}
},
"title": {
"text": "Win Rate",
"style": {
"color": "#8DAD36"
},
"margin": 2
},
"opposite": true,
"index": 1,
// "alignTicks": false
}],
"legend": {
"enabled": true,
"align": "center",
"verticalAlign": "top",
"x": 0,
"y": -5,
"borderWidth": 0
},
"series": [{
"name": "Revenue",
"type": "line",
"yAxis": 0,
"data": [5.4,27,27,27,58,0, 0, 0, 0
],"pointStart":1377993600000,"pointInterval":86400000
}, {
"name": "Win Rate",
"type": "line",
"color": "#8DAD36",
"yAxis": 1,
"data": [60,48,48,48,48,60, 0, 0, 0, 0
],"pointStart":1377993600000,"pointInterval":86400000
}]
});
});

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