Please add the feature of spacing between series3 votes
Can you elaborate on that? What kind of series? Where do you want the spacing? A sketch or screenshot would be helpful.
This would allow retrieveal of max and min data for that series. On a multi-series graph the axis extremes are nice, but being able to grab the extemes of each series would allow for more flexabiilty in data display.3 votes
I set up a plugin that you can use: http://jsfiddle.net/highcharts/acPw9/
Chart options strongly depend on chart type and other options. For example, ticks on x/y axis. Depending on what type was chosen (linear, logarithmic, datetime or category), ticks are configured differently.
And I really suffer when I read docs and don't clearly understand which properties work with others, and which are useless together.
I suggest you to update docs, or implement chart options validation, or even provide us some external service to check, if given options are valid. In ideal world, if options are not valid, it would say why and maybe suggest something.3 votes
Thanks for requesting! This kind of validation could be added to the debug module.
We do try to add information about conflicting options in the API docs however. Are there any specific cases that we failed to mention?
It would be great if the borders around the charts had similar controls to that of CSS where we could edit the border colors and thicknesses individually. My one example is that we need to have only the left border of a chart thick red while the rest of the borders are to remain thin and gray. Here is an example image: http://connect.urnerbarry.com/public/albumphoto/1d/09/0914e1ba.PNG?c=332c
I think it is a little bit too specific to add to the configuration API, but you can simple add this as a small plugin.
Being able to configure not just the fill colour of the bars in a chart, but the outline colour as well.3 votes
Styled mode is great but often with dynamically generated charts (i.e. when a user can customise a chart live) it would useful to be able to allow colours to be set on series. In our case we have a common look for all charts but also a colour picker.
Has the option of being able to set series colour in the same way as you would with styled mode turned off been considered? There's an argument that setting the series colour is data not presentation and therefore should be permissible with styled mode is enabled.3 votes
Yes I follow the argument – there are also series where the color is crucial, like heatmaps with a color axis.
In styled mode the idea is that you set the colorIndex instead of a color on the series, so you should be able to set individual series colors by linking the result of the color picker to the colorIndex of the series.
It would be nice to have a default formatter for displaying numbers in scientific notation3 votes
Here’s an idea of how to add a format for scientific notation:
Alternatively, Number.toExponential can be used inside formatter functions.
I want to do something after the tooltip shows.
And I found the "point hover" event
But when I use the "crosshair" option, it doesn't need to hover the points to trigger the tooltip, anywhere of the chart triggers the tooltip
So now I can only do something when user's mouse hovers the points
I want to do it when the tooltip shows,
So i think it's better to add a "after tooltip show" event in options.
You can use the internal chart.tooltipRefresh event: http://jsfiddle.net/highcharts/Ym4UA/
It would be nice to have an option to export chart (as PDF) to datauri string instead of file.
This can be done now indirectly, by obtaining chart's underlying svg, calling svg2pdf and finally using jsPDF doc.output('datauristring')
[which returns the base64 dataUri] instead of downloading file.
Maybe as an option in 'exporting' object?
Or by exposing new method, i.e. Highcharts.exportToUri() ?
Or maybe there's some simpler way that I am not aware of?
Thank you.2 votes
Thank you for your request! By extension, this applies to PNG and JPEG exports in addition to PDF. You can override the Highcharts.downloadURL function to capture the dataURI. See http://jsfiddle.net/highcharts/9my975x4/.
It would be great if there were a feature to add axis labels to the existing Sankey chart at each level. Something like this: https://i.stack.imgur.com/cYsNT.png
I notice that this has been previously mentioned in the Sankey Diagram thread (https://jsfiddle.net/7aa18mws/). However, in-built support for this on multiple levels would be great.2 votes
Thans for your suggestion! For the records, in the internal terminology this would be labels for the columns.
We have a requirement to generate Smith Charts. Can Highcharts support Smith Charts?1 vote
Currently Smith charts can’t be drawn with Highcharts out of the box.
For Highmaps, we should have a method to find which map area a point lays within. Useful for building heatmaps.1 vote
Thank you for your request.
When plotting a plodBand it doesn't plot the top border, if it's required to not plot the top border for some use cases, there should be an option to plot or not the top border.1 vote
The plot bands are only single shapes so we can’t currently give them individual borders. What you can do is to add a plotLine at the top value of the plot band.
Can we have any highchart functionality/feature that dashboard can automatically adjust width(HScroll bar) & height(VScroll bar) ?
Like chart should be overflow = auto (as per data)1 vote
Hi, with the new axis scrollbar feature it is possible to set a fixed range on the axis, so that the scrollbar is visible for longer series: http://jsfiddle.net/highcharts/fh0ormh5/
Currently the navigator is positioned at number 2 point in the axis array if new axis are dynamically added otherwise it is the last element. This makes indexing int the axis array unnecessarily complicated and confusing. I want that the navigator array either be taken out of the xAxis array and have its own array or at least have a consistent position1 vote
Use the xAxis.options.className to filter out the navigator axis.
When a border is added to bar/column charts, the border goes X pixels around the bar. This causes the bar to overlap over the axis lines and possibly other bars. See this JSFiddle example:
It would be nice if it could look more like this instead:
Simple plugin for you: http://jsfiddle.net/6kmu11md/7/
This would allow SVG paths to be shorter in many cases, which would reduce data size, and make the page load faster.
For example, SVG path for a rectangle could be
"M400 400L432 400 432 428 400 428Z"

Thank you for your suggestion.
add the ability to insert a custom class to data points matching specific criteria. If range is 1-9, if range is 10-19, etc.
If a data point is between X and Y integer, give it "class='low-range'" if a data point is between A and B interger, give it "class='custom-class'", etc.1 vote
Here’s how you can do this currently with a little extension: http://jsfiddle.net/highcharts/tc5b2vbr/
Plotlines are excellent to point out interesting Things in the chart. With large datasets it can be a good thing to be able to have an additional label for the exact value of that plotline1 vote
Thank you for your suggestion.
Reading a pie chart is like reading a clock. It's most effective to place the largest segment at 12 o'clock (as it does now). The best way to order the rest of the segments is to place the second biggest slice at 12 o'clock on the left; the rest would follow counterclockwise.1 vote
Thanks for your suggestion. For now, you can just sort your data by value before adding it to the chart.
