Marker rotation in Highchart - highcharts

Is there some way to rotate each marker by different-different angles?
lets say , In the following example, In series 1, the image markers should hv (30, 90) and in series 2, (150, 60) degree rotations respectively.
HTML
<script src="http://code.highcharts.com/highcharts.js"></script>
<div id="container" style="height: 400px"></div>
JS
$(function () {
$('#container').highcharts({
chart: {
},
xAxis: {
minPadding: 0.05,
maxPadding: 0.05
},
series: [{
data: [
{
y: 29.9,
x:0,
marker: {
symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)'
}
},
{
y: 71.9,
x:1,
marker: {
symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)'
}
},
[3, 106.4]
]
},
{
data: [
{
y: 60,
x:0,
marker: {
symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)'
}
},
{
y: 25,
x:1,
marker: {
symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)'
}
},
[3, 90]
]
}]
});
});
Code example

Unfortunately it is not officially supported, but you can use workaround, which iterate on each point and rotate by attr() function. It is not perfect, but you can use translate to move markers.
http://jsfiddle.net/yd8hV/2/
$.each(chart.series[0].data,function(i,point){
if(!point.angle)
point.angle = 0;
this.graphic.attr({
rotation:point.angle
})
.translate(10,-10);
});

Show tooltip on hovering anywhere in Y axis insted of column

Example Chart Image
I want to show tooltip for Approval Count as 0 on hovering anywhere in it's general vicinity, is that possible with highcharts?
You can render this particular column as a dummy point - full range & transparent color to show a tooltip for it.
Highcharts.chart('container', {
chart: {
type: 'bar'
},
yAxis: {
max: 10
},
tooltip: {
formatter(tooltip) {
if (this.point.isEmpty) {
return 'Null';
}
return tooltip.defaultFormatter.call(this, tooltip);
}
},
series: [{
data: [{
x: 0,
y: 2
}, {
x: 1,
y: 3
}, {
x: 2,
y: 10,
color: 'transparent',
isEmpty: true
}, {
x: 3,
y: 8
}, {
x: 4,
y: 2
}]
}]
});

}
}]
}
});
}
</script>
Is it possible to do it? And how to modify my code for it?
Thank you very much in advance!
As I mentioned in the comment current line shape is at it is because of the points positions on the chart. If you don't need to keep points actual positions the solution which you can use is to use the dummy data for the points and use the correct one in the dataLabels. See:
Demo: https://jsfiddle.net/BlackLabel/fshx3n50/
data: [{
y: 5,
z: 0.20
}, {
y: 10,
z: 1.40
}, {
y: 18,
z: 6.20
}, {
y: 30,
z: 18.00
}, {
y: 50,
z: 73.00
}],
I also changed the formatter function to display the z value in dataLabel:
formatter: function() {
return '<div class="chitem-time">' + this.x + '</div>' +
'<div class="chitem-val">' + Highcharts.numberFormat(this.point.z) + '<sup>REM</sup></div>';
}

Built linear gauge with highcharts (with pointer)

I'm trying to recreate a linear gauge chart of fusionchart in highcharts. This is the example that I am trying to recreate.
Head:

FusionCharts.ready(function () {
var cpuGauge = new FusionCharts({
type: 'hlineargauge',

}
]
},
"pointers": {
"pointer": [
{
"value": "2"
}
]
},
}
})
.render();
});
The highcharts chart must take over the following properties:
Negative values
At least 4 groups (colors)
Pointer (indication marker) with number at top
In addition, I would really appreciate if there is an animation where you can see the pointer moving.
The bullet graph from highcharts comes closest to the fusionchart. I have made a first step (example) with this graph

CSS:
#container1 {

But encounter a number of problems:
Negative numbers are not working
Pointer

Highcharts: 3D scatter data points projections

I am trying to create a 3D-scatter plot of some data with Highcharts. To make it easier to understand the 3D position of the data points, specially when using a still picture of the plot instead of the interactive draggable version, I would like to create projections of the data on each of the plot boundary planes.
It is not difficult to assign the corresponding position of these projections (example: http://jsfiddle.net/worg6jLz/1/), but I would like them to appear as real projections, not just as circles (or actually spheres) regardless of the perspective.
Is there a way to transform the plot markers according to their corresponding plane of projection, so that their shape is consistent with such projection regardless of the viewpoint?
Thanks.
$(function () {
// Give the points a 3D feel by adding a radial gradient
Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function (color) {

posY = eStart.pageY,
alpha = chart.options.chart.options3d.alpha,
beta = chart.options.chart.options3d.beta,
newAlpha,
newBeta,
sensitivity = 5; // lower is more sensitive
$(document).bind({
'mousemove.hc touchdrag.hc': function (e) {
// Run beta
newBeta = beta + (posX - e.pageX) / sensitivity;
chart.options.chart.options3d.beta = newBeta;
// Run alpha
newAlpha = alpha + (e.pageY - posY) / sensitivity;
chart.options.chart.options3d.alpha = newAlpha;
chart.redraw(false);
},
'mouseup touchend': function () {
$(document).unbind('.hc');
}
});
});
});
Bonus:
An additional interesting feature, though not the main purpose of this post, would be to draw lines linking the data points with their projections when the mouse pointer is placed over them.

Marker transform(translate) doesn't work

I need to translate the marker symbols by some pixels such that it doesn't overlap with the series line. But nothing seems working. Any suggestion?
Code:
$(function () {
$('#container').highcharts({
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
series: [{
marker: {
symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)',
},
data: [{
y: 10,
}, {
y: 25,
}, {
y: 12,
}, {
y: 31
}]
}]
},function(chart){
$.each(chart.series[0].data,function(i,point){
this.graphic.attr({
transform: "translate(-13,0)"
});
});
});
});
Jsfiddle link: http://jsfiddle.net/yd8hV/13/
You should wrap your $.each() function into setTimeout() function.
setTimeout(function () {
$.each(chart.series[0].data, function (i, point) {
this.graphic.attr({
transform: "translate(-15,-35)"
});
});
}, 50);
You need to do it because translate options are modified later than your callback function.
example:
