  1. This graph accurately and intuitively explains the min/max values along with 'standard deviation'. I felt this is more useful than a box plot.

  4. I have a chart where I mix and match different colors and stroke styles. It would be nice to have the possibility to have multiple legends, or at least the ability to create groups inside the legend, so I can better separate the meaning of the color from the meaning of the line style.

    and:http://highslide.com/forum/viewtopic.php?f=9&t=10642

    Add an option so that the precise start point of the grid lines/ axis labels can be specified

  6. In order to display two panes (price pane at top and volume pane at bottom) correctly when chart's container resizing, it would allow to set axis's top and height at runtime.

    Or another way you can do is to set axis's top and height value in percentage unit.

  7. Then Pareto graphs would look great even as series are added and removed.

  8. Addition of support to Network diagrams would make this utility perfect and complete.

  9. We have a user requirement, inspired from Yahoo/Google finance, ie:
    In case of single series( read first series, eg stock) they would like to see actual values on Y axis.
    but whenever a new series is added they would like to switch to compare percent mode and vice-versa.

  10. Large data sets may well include more data than can be presented, given the pixel size of the display. When a user zooms in on the data, more information would then be needed to display detail data.

    A progressive mechanism would be useful to allow more detail to be requested and sent to the client via an ajax call, triggered from a zoom event. This progressive rendering might show a lag on zoom, but in some cases this lag would be preferred to a long delay for initial data display for very large data sets. It might also perform better…

  11. If I've got a sparse dataset (e.g. to save space, duplicate data points are omitted), a line graph still represents the data accurately, however the tooltip only appears over the actual data points.

    Would it be possible for the tooltip to interpolate the data at the mouse pointer's position so as to show a value whether there's an actual data point there or not?

  12. 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.

  13. Highcharts doesn't currently appear to have any tree / node linking chart types. A few examples would be:

    The above chart types vary in their purpose and how they are constructed. But this request is simply to have some form of tree / node linking chart capabilities in highcharts.

    Once it becomes possible to chart a basic tree or hierarchy structure, it may be easier to extend functionality to create further chart types along the same thinking.

    Plot.ly currently offers both dendrogram's and tree plots within their python API.…

  16. It would be great to be able to post preview images of charts to Facebook, so that when a user shares a chart on Facebook, it shows an image instead of just a link.

  17. All animations in Highcharts use setTimeout. A new feature, requestAnimationFrame (https://developer.mozilla.org/en/DOM/window.mozRequestAnimationFrame) optimize all animations (CSS3, SVG, JS) to have a smooth rendering.

  18. Hi,

    Please make HighStock navigator a standalone component.

    It could have several usages besides driving the HighStock time:
    - immediate time selection/change for any web application - much more intuitive than just a Date + Time picker. Right now there's nothing similar: you have it, it's user friendly, but it' just not standalone.
    - use to zoom in and out several HighCharts (not HighStock) in the same page. Right now there's only a mouse based zoom (with and selection), but that's not very efficient when using more than one chart in the same page. Syncing those charts is still not…

  20. It would be great to have a range selector in highcharts that is the same as the highstocks one, with the draggable handles.
