I have been trying to clear this bug but i still not getting the point why it occurs.
check the code at http://jsfiddle.net/3RKL4/
The tool tip works only for the first and last points.
Is this a bug in highcharts or the code is wrong ?
If the code is wrong can any one help me ?
Ideally Highchart requires data to be increasing order of time. Your data doesn't seem to satisfy that, it doesn't work event with 3 points http://jsfiddle.net/jugal/3RKL4/5/
Reversing the order fixed it # http://jsfiddle.net/jugal/3RKL4/6/

I got a problem while using ApexChart and struggling so much on how do I could remove the one that I give 'X'?
So basically, what I want to achieve is like the light blue line that I draw.
On ApexChart, there's a specific styling for this - Curve's Stroke.
I want to use Stepline and Straight at the same time but I don't know how. So what I did is using 2 different series (dummy random data) with line and area chart type, then the first one using stepline curve and the second one is using straight.
It turned out I almost achieving what I need to do but, the problem is the 'X' blue mark.
I didn't want it like that. I want it just start a straight line after that specific last value/category/you know what I mean.
Is there any workaround for me to look? Can anyone help me?
I've been struggling about this for days and I'm getting crazy about it.

I was developing a solution for another question here on Stack Overflow (see Highcharts : selection) that has some simple slider elements (using input type="range") to change the categories shown in a column chart. Whenever the user changes the range in either slider element, the chart is redrawn using setExtremes().
I noticed that, in some instances, some of the x-axis labels disappeared, even when I moved the sliders back to their original positions. I've tinkered with a number of x-axis settings, including minPadding, startOnTick, and tickInterval, and none of them seem to solve "The Case of the Missing Labels."
The first screenshot below shows the chart when it's first loaded. All of the x-axis labels are present.
The second screenshot below shows the chart when I change one of the sliders. Some of the x-axis labels are now missing. It looks like they're being staggered.
Here's where the plot thickens: if I adjust the sliders to some other values, all of the labels come back:
Here's the fiddle I developed so you can see a live example of this behavior: https://jsfiddle.net/brightmatrix/uvat8u05/
I'm curious to know why this is happening, and what settings I could use to ensure that all x-axis labels are shown, regardless of what values the user chooses in the sliders.
Thank you very much!
Update: The responses from both Max Uppenkamp and Grzegorz Blachliński are valid and helpful solutions. What I also discovered by chance was that explicitly setting the slider values to integers using parseInt() solved this issue as well. It also helps in comparing both values to make sure a user doesn't choose an end date that is earlier than the start date.
This seems to be intended behavior of Highcharts, however inconsistent it may be.
According to this this should be fixed in current versions of Highcharts, but you might as well try this tick formatter solution.
Edit: If the above doesn't work for you, you might be able to solve the issue by rotating your labels:

I am trying to show a many line charts in one chart.
What's happening is that, instead of showing them all at the same time, you need to disable one to show another one.
Here is my jsfiddle;
What do I need to change in my code so it shows all of the graphs together?
Thanks folks
Try not to give the same Key names for your charts. NVD3 by default merges the duplicate Key names together.
After I changed the Key Name from you chart it seems to pick All the line charts correctly.
Here is a Working Fiddle of your code
Hope it helps.
I am using the Highstock library (not Highcharts) and I'm running into an issue I'm sure can be solved.
I need to add some dynamic information to each point on a series. Highstock has a built in tooltip that displays limited information about a point onHover.
I have tried adding a new property to the point at the time of creation; however, this new property is not available in the tooltip.
What's interesting is this exact functionality is available in the Highcharts library, but I would like to stick with Highstock if at all possible.
Here is a fiddle showing the desired result in Highcharts.
I have started looking around inside the Highstock javascript file looking for a way to expand the properties of the points that actually get added to the series and I have had some limited success.
I have added the property to the block beginning on line 8319 and again on ll320. This does seem to work, but only when the chart is zoomed in... very odd.
Has anyone tried this before, or have some insight on what I may be overlooking?
You can simply add own custom properties, then in tooltip you have access to them via:
this.points[x].point.options.your_property;
See: http://jsfiddle.net/dWDE6/199/
There is only one limitations which you should be aware of: when dataGrouping is affected all points are created as new one, so you don't have access to that custom properties.
I've been using the chart API to draw a cross sectional profile of a landmass, using a slightly modified version of the chart example shown here.
however, I now need to draw a line of sight between the two end points, as well as a Fresnel(1) zone between the two. can this be done through the interactive chart API? or is there a better way to get this done?
also, I would like to 'select' the first and last entries to display their elevation, however my code doesn't appear to do anything:
Chart.setSelection([{row:0,column:null},{row:Results.length - 1, column:null}]);
After finding some other problems with the visualization API, I just gave up and did the whole thing using Raphael instead, works way better :D
EDIT: didn't know you couldn't answer your own posts within two days :| kinda of annoying since I've spent like a week straight trying to fandangle the bleeding chart -.-
