I can't select the title and the chart categories . In some situations I need to select and copy those strings . Would You Please Add this opportunity ASAP?34 votes
Hi, this feature is prevented in two places, because there were problems with text being selected when trying to zoom in. See https://github.com/highcharts/highcharts/issues/3224.
If you want to enable text selection, there are two lines where the event handling is prevented. If you comment out both these lines, your users can select text:
It would be great to have a range selector in highcharts that is the same as the highstocks one, with the draggable handles.34 votes
It would be very convenient to pass several date formats to HighStock and use the scroll/zoom functionalities with those dates (without any transformation in UTC day-month-year-hour:min:sec).
For instance, astronomers use large time series but dates are usually formatted in "Julian Days", "Modified Julian Days" or Decimal Years (UTC) which are all double numbers. It would be nice to be able to see those values on the X-axis keeping the scroll/zoom functionalities.
UTC decimal years Ex : Date=[2012.345643, 2012.35432,2012.37234, etc...]
Julian dates Ex : [2456342.7345,2456342.7845,etc....]
modified Julian dates : Ex : [56342.2345,56342.2845,etc....]32 votes
There must be a provision to add labels for max, min, median in the plot itself apart from the hover. While taking print, it would be great of the labels are printed for ease of use.32 votes

Include options to set up custom buttons with call-backs to perform certain functionality.
For example, I would love to be able to have a button next to the current print and export buttons that would be used for help/information about the chart.31 votes
Here’s how you do that: http://jsfiddle.net/highcharts/2F4pJ/.
It has always been around, but perhaps we need to document this more clearly.
I bumped to this question https://www.highcharts.com/forum/viewtopic.php?t=42309 and also this linked question https://stackoverflow.com/questions/56153029/higcharts-gantt-chart-with-table-and-sub-tasks. Got me wondering why this is not posted yet. Is this possible?31 votes
Currently, it is observed that Sunburst chart series data labels when shown, overlap or only the show/hide behavior of data labels can be achieved through the formatter function.
Refer the Sunburst chart's series data labels on the following link:- http://www.dundas.com/support/blog/sunburst-charts-homerun-or-groundout
Expected behavior is to configure the series data labels in such a way that if the arc size of a node is less than a particular value, instead of hiding the data label, show it outside the leaf level nodes of the chart, also adjust the distance of data labels and its connectors from the chart.31 votes
I would love to be able to set background color for labels on the yAxis.plotLines:
I have a column chart that can have a variable number of columns. I would like a slight gap between each column, but I'd like it to be consistent no matter how many columns there are or how wide they are. I've tried groupPadding and pointPadding, but if you use a static value the padding seems to vary depending on how wide the columns are. See this example:
It would be nice to have a way to define a fixed padding in pixels or points that always stays the same.29 votes
If you have a band title that exceeds the width of the band it currently overflows in unattractive ways. It would be nice if there were a few options for situations where the title exceeds the width of a plot band like:
- Crop (with optional center, left, right, alignments)
- Bleed into neighboring plot bands (the current behavior that may not ALWAYS be undesirable)
Currently, the buildText function doesn't render subscripts and superscripts in the SVG output, but subscripts and superscripts are supported in SVG 1.1 using the baseline-shift attribute on the tspan element. Please add support for parsing <sub> and <sup> tags and rendering them as appropriate tspan elements.29 votes
When using a shared tooltip and horizontal crosshairs, the crosshair will only display on the first series drawn, if there is more than one. Even if the cursor starts out tracing along a different series, the crosshair is pinned to the first series drawn. Could this behaviour be modified so the crosshair is associated with the series the cursor is highlighting?29 votes
It'd be useful to have access to some more events, specifically I was thinking about 4 new events which could be captured and managed by dedicated handlers: onStartPrint, onFinishPrint, onStartExport and onFinishExport
The first two are related to the act of printing the chart via the print button, the other two are related to chart exporting.28 votes
Here’s a proposal for startPrint and endPrint event: http://jsfiddle.net/highcharts/k1o2w9ba/
If the 'y' value of a point is null for a line type of graph, then option should be available to either automatically switch to a dashed line or not to display the line entirely till 'y' gets set to non-null value28 votes
Here’s a proposal for how you can extend Highcharts to draw a graphic for null points: http://jsfiddle.net/highcharts/FKSZ6/
- Don't see your idea?
