How to change bar width of a specific series while in different axis target - Angular google charts

I am developing a layered column chart using ComboChart on Angular google charts. Although I've separated two series of bar charts in two different axis, being able to find a bar in front of the other, like needed, I can't change the width of one of the series only. I want a result like the amCharts Layered Column Chart:
Layered Column Chart example
Right now, the chart looks like:
Current chart - Angular google charts
Also, if there is a way to share the same y axis while keeping one bar in front of the other, instead of staking then, it would be great.
The code I've been using for options of the angular google chart:
this.options =
{
colors: ['#1E90FF', '#f39800'],
hAxis: {
title: 'haxisTitle',
type: 'category'
},
vAxis:{
title: 'Value',
minValue: 0,
format: this.numberFormat
},
seriesType: 'bars',
bar: {1: {groupWidth: "30"}},
series:
{
0: {
targetAxisIndex: 0
},
1: {
targetAxisIndex: 1,
}
},
vAxes: {
0: {
title: 'Altered Value',
label:'Altered Value',
viewWindow: { // <-- set view window
min: 0,
max: this.maxValue + 0.1*this.maxValue, // Sets the maximun value of altered or real value to the window size (both axis)
},
format: this.numberFormat,
type: 'bars'
},
1: {
title: 'Real Value',
label:'Real Value',
viewWindow: { // <-- set view window
min: 0,
max: this.maxValue + 0.1*this.maxValue,
},
format: this.numberFormat,
type: 'bars'
}
},
aggregationTarget: 'auto',
stackSeries: true,
isStacked : true,
explorer: {
actions: ['dragToZoom', 'rightClickToReset'],
keepInBounds: true,
maxZoomIn: 4.0
}
};
}
The chart shows the data correctly, the only problem is the layout.

How to hide date time x-axis but still be able to show plot lines in Highcharts gantt chart?

I want to disable or hide marked x-axis on the following image:
But I still need to be able to show a plot line.
I tried to play around with "xAxis" Highcharts property and I am able to hide marked x-axis, but then I can not add a plot line. It seems to me this axis is somehow connected with the plot.
Thanks a lot for help.

The plotLines are connected to an axis, but you can separately disable the grid and the labels:
xAxis: [{
...,
grid: {
enabled: false
},
plotLines: [{
color: 'red',
value: today + day * 7,
width: 5
}],
labels: {
enabled: false
},
tickLength: 0
}, {
visible: false
}]

How do you position the x-axis labels along the line y=0 using Highcharts?

I'm trying to move the x-axis labels so that they appear along the line x=0. The scales are constantly changing, so I don't want to set the location using pixels, as y=0 may not be in the same location for each plot.
I tried looking up this question on this site and someone recommended using "crossing:0," as shown below, but that doesn't work.
xAxis: {
min: -20,
max: 20,
tickInterval: 1,
gridLineWidth: 1,
endOnTick: false,
crossing:0,
title: {
text: 'some value',
},
If someone could help me with this positioning, I would appreciate it.
Here's my JsFiddle: http://jsfiddle.net/z7eyv/35/

crossing is not an out-of-the-box feature of Highcharts.
Based on what I could find, it seems what you want is the "Crossing-Specific-Value" Highcharts plugin, which is located here: http://www.highcharts.com/plugin-registry/single/6/Crossing-Specific-Values
Update (July 5, 2016): To address the comments about your fiddle, you need to explicitly add the "Crossing-Specific-Value" plugin after your bring in the Highcharts library (see the third line below):
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<script src="https://rawgithub.com/highslide-software/crossing-specific-value/master/crossing-specific-value.js"></script>
Now, adding the crossing variable to your x-axis will show the labels as in the demo.
I made a few tweaks to your fiddle (see http://jsfiddle.net/brightmatrix/z7eyv/38/) to better suit what you're asking.
1) Using the demo as the default, it seems that the plugin puts your labels above the axis line. I've seen instances where the labels are better ready below the line so I did the following:
xAxis: {
crossing: 0,
opposite: true,
min: -20,
max: 20,
tickInterval: 1,
gridLineWidth: 1,
endOnTick: false,
title: { text: '' },
labels: { y: 15 } // pushes the labels down below the crossing line
},
2) I then adjusted the plot line for the y-axis as follows:
yAxis: {
min: -20,
max: 20,
tickInterval: 1,
endOnTick: false,
title: { text: 'some value' },
plotLines: [{
value: 0.1,
width: 1,
color: 'black',
zIndex: 10 }] // moves the plot line above the axis gridline
},
The zIndex value of 10 means the line will show up on top of the normal gridline. Here's how this looks:
Please let me know if this better answers your question.

Highcharts bar and scatter series not lining up

I'm trying to create a chart using highcharts that includes both a column series and a scatter series with a custom point marker. The series will contain slightly different sets of data, but will overlap for the most part and will always have the same x-axis values.
I've set it up, but the problem is that it's not lining up perfectly. Some of the scatter series' points are shifted one or two pixels to the left of the corresponding bar.
Any ideas about how to fix this?
{
chart: {
animation: false
},
xAxis: {
tickInterval: 1
},
series: [{
type: "column",
borderWidth: 0,
pointWidth: 20,
name: "col"
},
{
type: "scatter",
states: { hover: { enabled: false } },
marker: { symbol: 'url(symbol.png)' }
}]
}
And here's a screenshot of what's happening:

Indeed it looks like a bug, also with standard markers, so I've decided to report it to our developers https://github.com/highslide-software/highcharts.com/issues/1843

HighCharts - HightStock inverted axes with scroll navigator

I'm trying the Highcharts tools to display some graph with huge amount of data and series comparison.
the king of graph I need is exactly the one given in this example.
Except that mine has to be displayed in vertical ( with the time line on y axis, from the top to the bottom, and value on the x axis)
like the 'spline inverted' example ( seen here ) show, it's quite useful to display altitude related data for example.
I can easily imagine to invert values and exchange axis legends, but I don't think the time line navigator will follow...
I also tried to set the graph as inverted like in the 'Spline with inverted axes' example :
chart = new Highcharts.StockChart({
chart: {
renderTo: 'container',
inverted: true
},
...
but it didn't work.
Is there a way to display the exact same graph in vertical with the time line navigator on the y axis ?
EDIT : its seems its not possible to use invert on HighStock graphs (as seen in doc),
So I adjust my question :
Can we use an HighCharts inverted graph to display as many points that in HighStock charts ? (even if we won't get any scroll navigator on the y-axis)

Highstock doesn't support inverted charts, see: http://api.highcharts.com/highstock#chart
EDIT:
It is possible to use inverted Highcharts with dataGrouping, it of course requires Highstock in files, but just create chart using Highcharts.Chart(). Don't forget to enable dataGrouping from Highstock. See example: http://jsfiddle.net/PATyv/2/
Code:
window.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
inverted: true
},
title: {
text: 'USD to EUR exchange rate'
},
tooltip: {
style: {
width: '200px'
},
valueDecimals: 4
},
yAxis: {
title: {
text: 'Exchange rate'
}
},
xAxis: {
type: 'datetime'
},
series: [{
name: 'USD to EUR',
data: data,
id: 'dataseries',
dataGrouping: {
enabled: true
}
}]
});
