Highstock with numbers instead of date in x-axis - highcharts

I need to output a plot on page, and I'm considering Highstock or Highcharts to implement this. Highstock interface is more preferable due to navigator pane showing the rest of plot after rezooming.
However my plot has numbers in x-asis, but not date/time. Is there any way to use Highstock with numerical x-scale? Or add similar navigator to Highcharts?

Below X Axis formatter can be used with high Stock for displaying numbers in X-Axis:
xAxis: {labels: { formatter: function () {return this.value;}} }

Highstock's only type of xAxis is datetime, so using it with numbers is not an option. (Maybe if you make some tricky formatting actions and define a custom tooltip with the same formatting options it might be possible).
Leaves only Highcharts and there is an example called master-detail chart that could meet your requirements.
Hope that helps.

xAxis: {
type: 'linear' // Other types are "logarithmic", "datetime" and "category"
},

How can I plot the x-axis on a highchart like this?

I'm building a chart using the highcharts javascript library
I'm expecting to get a chart like
And here's what I already have. enter link description here
enter code here
You define x values on a categorized axis and because of the default pointPlacement, your chart is distorted. You can change pointRange, but in that case, I would recommend removing axis type (the linear will be by default) and set series.pointPlacement to between
plotOptions: {
column: {
pointPlacement: "between"
}
},
The label's position can be set by xAxis.labels.x option.

Adding same precision to the yAxis Label of HighCharts

I want to format the yAxis label and add trailing zeros after decimal. The number of precision will be decided dynamically as per the value of yAxis labels.
For Example: If there are 3 labels in yAxis with value 95.8, 95.825, and 95.85. then, it should be displayed as 95.800, 95.825, 95.850.
Edit:
Actually, the requirement is to have the decimal precision dynamically. Actually sometimes, our chart shows labels as 93,94,95, in this case we don't want to add precision. The idea is to add same precision, if the chart is generating, yAxis labels like 94.25, 94.5, 94.75, then, I want the chart to show yAxis labels as 94.24, 94.50, 94.75.
For dataLabels there are some format parameters you can add to your y values.
You can add this to the plotOptions structure like this:
plotOptions: {
series: {
dataLabels: {
enabled: true,
format: '{y:.3f}' // <<< .3f is 3 decimal places out.
}
}
},
Here is a modified fiddle:

EDIT:
Sorry the example above was just for datalabels...Here is an improved example that shows, xAxis, yAxis, dataLables and toolTip with different '3 decimal place' approaches.

Highstock Highcharts dates don't lineup

I have a Highstock chart with Navigator which is synced to 4 Highcharts on same page. The Highstock dates don't line up with Highcharts dates plus it's a different format.
Highstock and Highchart:: xaxis:
xAxis: {
type: 'datetime',
dateTimeLabelFormats: {
year: '%Y'
},
events: {}
},
Here's the site I'm working on, the file is to large for here. Click on any icon, then pick "Data and Charts". The top chart has a different date format and the bottom charts points don't line up with top chart. I'm sure its default behavior of both Highstock and Highcharts but I can't find a way around problem.
Any help would be greatly appreciated,
Michael
Your first chart, being a Highstock chart, has an ordinal x-axis (API). The other charts do not, as it is not part of Highcharts. You can solve this by setting it to false for the first chart:
$('#container1').highcharts('StockChart', {
xAxis: {
ordinal: false,
// ...
}
// ...
});
This also seems to fix your date formatting problem (I'm not sure why).

Prevent xAxis of column highchart taking negative labels on hiding one of other series(on legendItemClick event)

On hiding both the series using legends, and then clicking one of the series shows xAxis starting from '-1', when ideally it should show only not null categories.
Using 'ignoreHiddenSeries: false' solves the purpose but again on hiding both the series using legend and then enabling other series tends to overlap both the series. Although on window resize event, series get aligned properly.
chart: {
type: 'column'
// ignoreHiddenSeries: false
},
Example for reference: http://jsfiddle.net/t88rc/
You can simply set for xAxis min:0, see: http://jsfiddle.net/t88rc/2/
Grouped column charts work best with equal number of data points per series.
Best solution I have found for this is to fill any missing data points with null values:
http://jsfiddle.net/jlbriggs/t88rc/1/
data: [49.9, 71.5,null,null,null,null,null,null]

Using a plot line comparator in Highcharts

I use Highchart to display an inverted graph with multiple series.
an HighStock chart should be better for what I need but I had to use it with the inverted option that is available only in HightChart.
How can I display a comparator line following my cursor on my multiple series chart ?
( like in this example from HighStock )
secondary question : why is it so many differences between highstock and highcharts ?
would be perfect to use the better of those two worlds together.
Ok I've found it.
using the tooltip shared option as:
tooltip: {
shared: true,
crosshairs: true
}
it works great on inverted charts too, the misunderstood was because this setting is enable by default in HighStock graphs.
