Highcharts xAxis text matching series name - javascript

I'm facing an issue with my Highcharts-powered component.
Considering the basic column chart JSFiddle example: http://www.highcharts.com/demo/column-basic
My goal is to get the series name (Tokyo, New York, etc...) instead of Jan, Feb, Mar... on the x Axis.
Of course, I also need the columns to be grouped according to the series name. So, in this case, it would be 4 group of columns.
How can I do this ? Should I modify the categories block ?
Thanks a lot
EDIT
I've found the solution and updated the fiddle: http://jsfiddle.net/j658R/1/
But now, I need another bahvior. How can I specify more than one value for each serie ? For example, for "s1", how can I put 4 values for this series and so get 4 bars above the "s1" label on the X axis ?
Thanks

By separating each data point into a separate series, Highcharts will automatically group the data.
So the first data point of each series will be set to the first category. The second data point of series to the second category, etc.
All you need to do is set this up as a single series:

Display Categories on x-axis for Highcharts spline with x and y data

My data needs to have an x and a y value, because I want to show the x value when the user hovers over the chart.
I only want to show a limited amount of labels on the x-axis though, which is why I am using categories. I keep getting Highcharts error #19 though, because the chart apparently tries to use the x-values provided in the data array.
I've played around with using type: 'datetime', since I am working with timestamps but I can't position the labels properly in this case and want to use categories instead.
I've created a jsfiddle to explain my problem: http://jsfiddle.net/kf6wrj37/
Instead of just the first and last x-value being display, I want my categories array
categories: [
'1453417200000',
'1456873200000',
'1460325600000',
'1463781600000',
'1467237600000',
'1470693600000',
'1474149600000',
'1477605600000',
'1481065200000',
'1484521200000',
'1487977200000'
],
to be displayed as labels on the x-axis.
How should I go about this? Is it even possible to use categories when my chart's data has x and y values?

Append data count onto different series

I have 2 datatime series (A & B)
Xaxis should be time and yaxis is count.
If time t i have 1 value on serie A, graph will show: [x=t, y=1].
If same time t i have one other value on serie B, I would like that value to be show: [x=t, y=2].
At the moment I modify 'manualy' values on serie B.
I wonder if there os a built-in method in highcharts to have that behavior?
Thx
Ok, so in that case you would have to create some custom code that gets all data, checks for occurrences of the same dates and based on that information set appropriate y values for points. I have prepared a simple demo where all emails are correctly arranged on the chart.

Highcharts not displaying daily data for column chart

So I have a stacked column chart, type of datetime, with minTickInterval of one day. In some cases for my data, my chart displays fine, with each stack in its own day, but for other cases, the column seem to overlap and instead Highchart does a "week of ...". I have no idea what could be wrong in the config. Here is the fiddle
I already tried this with no luck
dataGrouping: {
enabled: false
}
First thing I notice is that your data is not for the same timestamp. This means that the data will not stack as their x-values are different. If you want all data to for a given date to be stacked then you have to give them the same date (and time). The dataGrouping only applies to HighStock. Your toolTip text can be formatted.
The cahrt is displayed correctl,y becasue you have stacked for the same x value, for for different, points are neighbours.
For each series data, I had to use
pointRange: 86400000 // equal to one day
The first answer here solved it.
Highcharts columnchart: How to seperate overlapping columns

Highcharts, multiple parts chart

What whould be the best approach to do something like ?
I think I need to do 2 charts or can I do it in the same ? I don't know how to separate the 2 parts.
Labels translate by "Late" and "Next". It's 2 different series
One method is to make your "red" series use negative values and your "blue" series use positive values. To make the labels on the xAxis be positive you would make the xAxis label formatter use an absolute value of this.value.

Stacked Bar And Scatter Alignment

I have a chart here: http://jsfiddle.net/wergeld/bx82z/
What I need is for the stacked bars and the scatter points to line up on each other based on the data X-element (county name in this case).
Getting the bars to stack was simple. But as you can see in the example the scatter points show up in the middle of the chart - not on the same x-value as the others.
I suppose I could create a category list (using the county names) but there may be cases where I do not have all 3 data elements for all counties - how to handle that scenario?
I did great the category axis and it is still doing the same thing: http://jsfiddle.net/wergeld/YckwW/
You were not defining the series correctly to achieve what you were wanting. See updated jsfiddle for what I think you are looking for.
In the cases where you are missing a piece of data for one of the countries you could always use null, which simply means there is nothing to display for that data point. See Missing Data Sample for an example. It is case sensitive so make sure that null is all lower case.
