  1. Feature to save Image/PDF on Server Side (like the feature to save it on client side). This would ease in building email functionality. If highcharts can save the generated pdf on a server by means of a button click, we can write an email client to pick that up and send as an attachment.

  2. I need the possibility to show a tooltip for plotBands.

    The solution described in http://forum.highcharts.com/post117159.html#p117159 is far to complicated. I'd prefer a single attribute and the handling within highcharts.

  3. Currently, timezone is global to the whole Highcharts library. It would be great if it would be per chart/instance. We have data sources coming from all around the world and we would like to display data based on their local time, for each data source.

    Maybe the easiest solution would be for getTimezoneOffset to get chart instance object as a second argument?

    But the cleanest would be to make this per-chart (or even per series) option.

  5. With Highchart version 3.0, the chart does not get rendered on mobile orientation change. I am not sure if this is available with Hightchart ?

    Highcharts doesn’t do anything internally on orientation change, except it reflows if the window.resize event fires.

    You can add your own listeners to orientation change though.

    What does the case look like? Is there a problem?

  6. Right now when using a treemap squarified the borderRadius is not accepted for each individual rectangle composing the treemap. It would be very handy to have that.

  7. With Google spreadsheet integration Highcharts makes more sense. However it would be great if highchart cloud is also supports REST apis with public and private api support (allow storage of credentials/authentication).

  8. Consider this chart where one series has a missing value. JSFiddle: http://jsfiddle.net/pclaar/zmktekak/2/

    (Note that New York does not have a value for February.)

    I would like to instruct HighCharts to remove the gap created by the missing data point, effectively showing three points for February.

  9. 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:
    http://jsfiddle.net/aaewong/6kmu11md/5/

    It would be nice if it could look more like this instead:

  10. I’m using a bubble chart to display positive and negative data, and I have the data dynamically updated like in this example: http://jsfiddle.net/0jcaqnL4/3/

    The problem I have is that the bubble that becomes negative, while turning the correct color, has a confusing animation that appears as if the bubble is growing. We’d like to see an animation in which the bubble first shrinks all the way and then grows to the correct negative size.

  12. Allow the ability to set language options within a specific chart configuration. This would override any global language settings.

    $('#container1').highcharts({
        lang: {
            numericSymbols: [' thousandzzz', ' millionzzz']
        },
        series: [{
            data: [0.029, 71.5, 1.06, 1292, 14400, 1.760, 135]
        }]
    });

  13. Resize/Redraw to Container Size when printing whole webpage via Browser. To be able to customize a print layout with CSS @media print.
    Very useful when printing multible highcharts on a single paper/pdf page.

  14. Hi, I am not sure whether this is right place to put this link http://jsfiddle.net/roytirthadeep/pupk16ys/9/,
    please excuse me for the same

    For the last couple of days I am trying to figure out a way to apply axis.breaks dynamically. But, the issue is breaks are applied properly based on the break size specified but the ticks are overlapped. How to resolve the issue.

    Steps:
    - Start and wait for sometime (5 secs)
    - Pause and wait for sometime (5 secs)
    - Now, click start again, we can see the ticks are overlapped.

    Is it possible the same using axis.breaks…

  16. There is minPointLength for bar charts, but nothing for pie charts. When we have a pie chart in which the numbers differ greatly, the smaller sections are not visible.

  17. Making the default set of line colors not be a multiple of the default set of symbols would make it easier to distinguish more lines on a chart. At the moment red lines always have triangle symbols. By adding one more color each time the first color was reused it would be on a different symbol.

  18. If we can apply different themes to different charts on same webpage, that will be good. Because if we apply same highcharts theme to all charts that changes all charts color combination (column, pie, bar etc). If it is possible to add a particular theme to particlular chart so that colors of column, bar, pie will be according to defined in theme.
    By doing this we can create a single js theme file for all charts, which will contain all same css for all the charts and different theme for colors of column, bar, pie, heatmap etc.

  19. When building a scatter plot with multiple points with the same coordinates, there's no visual cue or ability to inspect the different points on the same coordinate. Add the ability to display a single point that represents multiple points and then allow the user to expand the single point in to multiple points.
