Add x-axis scrollbar support to Highcharts
Providing the scroll feature will help to show the chart with more numbers of x-axis values. We have a scenario where the width of the chart is fixed, but the number of values for x-axis is more. We can not change the width as that is fixed as per our screen layout requirements. Now in this case scrolling will enable us to see the graph properly. Please let me know if any screen snapshot if required for the same.
1 voteIn short, you can borrow Highstock’s scrollbar in Highcharts too, but you need to consider licensing.

fire the selection event for Stock navigator or rangeSelector changes
chart.events.selection() does not appear to fire for Highchart Stock navigator or rangeSelector changes. This makes sense because it's the same as a zoom selection on main pane.
I'm using the selection event to return to the server and retrieve higher-resolution data (a drill down), but this fails when these other navigation changes take place. The redraw event does not work because it fires too often.
1 voteThe selection event only applies to graphic selection. Instead, use the xAxis.events.setExtremes event, which fires in all these cases.

Add the highstock scrollbar to Highcharts for master detail charts
I have a master-detail chart - pretty much as per the highcharts demo, except for the fact that the detail data is ajax loaded in an appropriate resolution as the extremes are set. I would much prefer to use the time selector from highstock, as it's a lot slicker.
An alternative would be to provide a way to have separate master and detail data sets for highstock, with the ability to ajax load detail data when a time range is selected.
3 votesHighstock will replace the master-detail chart altogether. In fact, the master-detail chart was just meant as a preliminary solution until we got to finish Highstock.

python interfacing
Like psycopg2 for postgresql interfacing, why not python-highcharts interfacing ?
1 voteThis belongs to a more general request for backend integration.

Highstock should incorporate a Refresh/Update option
When working with a chart that does dynamic updating from the server, it would be nice if there was a button in the Highstock UI that allowed the user to disable or enable the dynamic updating. Under the hood, the API could be as simple as specifying the name of a JS function to call and the interval. Turning the button on would call setInterval() and turning the button off would call clearInterval().
3 votesThe Highcharts API actually doesn’t do the interval, it only supplies methods like series.addPoint. Handling intervals is done outside the Highcharts API, in the general JavaScript setup.

Updating charts aren’t really a Highcharts option, it is a way of using the Highcharts API. So to pause it, you would just use the API differently , for example by adding a button that clears your JavaScript timeout responsible for the updates.

Hide dataLabels when value = 0 (optionally check if minPointLength is also 0)
My stacked bars show dataLabels even though the bar itself is hidden, because it has a value of 0
3 votes0 is also a value, so this behaviour is by design. If however the value is null, the data label should go away. If you want to treat 0 as null, you can return null from the data label formatter.

In Highcharts, the data is already sorted. We removed this feature from the Highstock branch and will do so in future Highcharts as well, because of the performance overhead. You should make sure the input data is sorted the way you want it.

My spline chart looks different in Chrome than in other browsers

Locale
There should be a setting for internationalisation so that the dates are properly displayed in the local language.
"en", "es", "fr", etc... for english, spanish, french, etc...3 votesIt would add too much footprint to include all language strings in Highcharts, given that most websites use only one language. Currently you have options for number formatting and date formatting in http://www.highcharts.com/ref/#lang and in each property’s formatter.

RSS
hello dear highChar
please help me to add RSSFEEDs to creat chart automaticaly3 votesHighcharts is a client side charting library, so this would typically be a job for a custom backend. Please use the forum for tech support.

show only the top N values
Allow the user to input many values, but only chart the top N values.
Eg, I have a census table showing the languages spoken - there are around 200 possible answers. This is too many to chart, so I'd like to show only the top 10 values.
This is possible with some pre-processing, but would be easier if the HighChart could handle it internally
1 voteI don’t think this kind of data handling should be up to the charting library. It is a special case, and typical case of preprocessing.

Add an ajaxSource property and reloadAjax method to the Series object for more streamlined JSON load
3 votesThis was part of Highcharts 1.x, but was deprecated in 2.0, as it is cleaner to let jQuery handle all Ajax stuff. Best practice is to first load the Ajax data, then display the chart as shown in the how-to.

Color picker on legend
Make the colors in legend squares instead of lines/points, when clicked, a color palette picker will popup and let you change colors.
6 votesI think this is a bit outside the natural scope of a charting application. You can build this by attaching a color picker script to the legendItemClick event.

client side pdf export of an entire html results page including multiple charts and tables
Allow a fully rendered page that includes several charts, tables, images and text to be exported by the user to a PDF document.
3 votesIt can’t. On the client side however, you can export a complete page through a software program called wkhtmltopdf.

add html support to data labels
I would like to see a full or an extra html support in data labels. This would allow to add images, divs and anything that is not pure text.
3 votesFull HTML support isn’t planned because it wouldn’t be visible in the exported chart. A subset of HTML is already supported by the data labels. You can add spans, anchors and styled spans within the text.

generating charts with SQL queries
I think it shoud be great to give a way to generate chart only by passing a SQL query.
Like it can be done with jaspersoft.
I know javascript can't do this without a server side script but it should be very interesting and will be a very big steap to make Highcharts very easy to use.
3 votesI’m afraid this would fall outside Highcharts JS’s scope as a client side charting library. Also, sending SQL strings from the client would mean a security hazard.
This should be handled by each installation’s backend, alternatively Highcharts server plugins.
