  1. I would like to have an approximation function in which we can access all the information from the points instead of just the y values. This allows me to not only decide how to group but also an ability to capture information from all the points into the grouped point.

  2. It would be nice if it is possible to create a bar chart with labels like the pie chart. I need to be able to create the labels outside the column and create that line to them. Just like the pie chart does here:
    http://www.highcharts.com/demo/pie-basic

    I have a Stacked Bar Chart that shows percentages and the labels wont be visible if the value is too small. or if I make them visible they will be overlapping.
    Here is an Example Fiddle to show the problem

  3. If I tend to display huge volume of data, chart GUI is not stretching to accomodate all contents, instead it reduces their dimensions to incorporate them within given area. This makes chart unreadable, also leads to overlapping of data during display. It will be great if chart length grows horizontally on more data and provides a scroll bar

  4. Would like the ability to keep the tooltip shown after the users mouse has left the chart. Pretty easy to add.

    Add option tooltip.sticky

    Current 3.2.0.
    Line: 1613. Add sticky: false.
    Line: 8672. Add && !chart.options.tooltip.sticky.
    Line: 8618. Wrap with if statement (!chart.options.tooltip.sticky).

  5. It would be most useful to restore the "target" option in the "credits" configuration so that when the user clicks on the credit text (usually in the lower right angle of the graph), the link can be opened in a new page instead of the current one.

  6. I would like the tooltip to have a 'initial delay' - such that it acts more like a typical tooltip. I.e. the tooltip only shows after the mouse is stationary for a specified time, and then tracks data points instantly once shown.

    Additionally, I would like the tooltip to be able to be replaced by a callback which provided the point values, such that they could be displayed elsewhere. So, for example, I might want to display the values of the currently tracked points in a div to the right of the graph, while still retaining the crosshair functionality.

  8. It should be possible to sum up negative and positive values in the same stack (like excel does for area charts by default).

    Currently positive and negative values are stacked seperately above and below the x-axis. To keep BC and keep the old behaviour as well a new stacking mode should be added IMHO.

  9. For the slices of a pie chart, allow the user to specify border attributes differently for inside, outside and separator borders. I would like to specify no border for the outside and inside of a donut chart, but still have borders between the slices.

  10. Hi

    I would like to suggest a small improvement concerning exporting. At the moment, user that wants to save a highchart has to click on a download icon and choose an option from a dropdown.
    A small but great improvement would be to do the same, just by right-clicking on a chart.

    You just right click on a chart -> save as -> desired format and voila!
    I am not sure if sucha feature is possible to implement, but it would be neat to have this! :)

  11. It would be great to control line breaks completely using non-breaking spaces ( ), <br> tags and soft hyphens (­).

  12. Auto-Plotlines for aggregate functions like Min, AVG and Max based on the series values.

    This would be accessible via the series or plotline objects and would draw the lines automatically (ui default properties for each plotline defined as well and not null) for the aggregates on the values of the series.

  13. Scatter and bubble charts do not seem to support collision avoidance for data labels. Along with collision avoidance, connectors that link the points to the data labels would be very helpful.

    Thank you for the great library.

  14. A "ribbon chart" which is a new way to look at a stacked area/column chart. Looks much prettier and easier to compared to the normal stacked styles that have commonly existed in most chart systems.

    This site wrote up an article about the style being added to another chart system.

    http://radacad.com/ribbon-chart-is-the-next-generation-of-stacked-column-chart

    thanks!

  16. Provide some way of including an image in an axis label. For example, I may want to prefix the axis labels with an icon.

    I've tried including HTML in the axis label and using axis.labels.formatter to add image HTML into the label. Neither worked. I've seen reference to using renderer for doing this, but I haven't been able to find an example.

  19. What I am after is to do exactly what the tickmarkPlacement:'between' setting does for categories. Except I need it for dates. This is a pretty fundamental charting option that should be available.

    If I'm doing a chart that is over 12 months and I'm showing the months on the xAxis, I want the labels to be in between the ticks as that represents the month not on the tick that separates one month from the next.

    If there is a way of doing this I would love to know. I can't use the label x setting as the charts are…
