  2. add margin setting between top of chart area and zoom / data range row. currently one has to set top variable for all axis to move them all uniformly, also offset for axis labels and axis title not uniform, they should all take into account the opposite value of axis and move as group, also spacing between labels and axis title not dynamic, the width of the labels can leave to much space or to little, even overlap. comments specific to highstock, not sure if highcharts works same way

  5. Currently, when clicking < or > of scrollbar, the time line moves.
    But when pressing < or > of scrollbar, the time line doesn't move.

    Our users want to be able to move the time line continuously by pressing the button of scrollbar. Can you enhance it?

  6. We are using a touchscreen.
    At highchart there are two small buttons over the scrollbarbutton.

    http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/stock/scrollbar/height/

    I am not able to change the dimensions of this small buttons which are used to change the timeselection.
    This property can also be combined with the dimension of the scrollbar { height: XX, width: XX}

  8. Will you plan support the connectors between bubbles
    ( http://www.highcharts.com/demo/bubble)
    since the connection between bubbles can express the figures more details.

  10. An option for what to display in place of missing data. Currently, you can override the formatter for data labels, a simple '==null' test would work. The issue is that the formatter and display for the label is skipped on null elements in series. Could there be a second option, an incase-of-null display hook?

  11. Currently in Highstock, if you're editing the date/time range by using the text fields, you can't hit Enter to make your changes, which is odd. Instead, you have to click the page outside of the text field. Support for hitting Enter should be added.

  12. How shall we add patterns and visibility of series in venn diagram? So that can represent the intersected data in patterns and can also disable the unwanted circle through aps by controlling visibility from aps. If you have any kind of solution kindly reply as early as possible.

  13. The draggable-points module handles logarithmic axes pretty bad, see this fiddle: https://jsfiddle.net/5bkf7pL8/2/

    I did however find an old stackoverflow issue regarding this ( https://stackoverflow.com/questions/18036117/high-charts-draggable-not-working-for-log-scale ) where a solution was found for the old experimental plugin.

    This example ( http://jsfiddle.net/yn1jaL60/ ) shows that dragging is freely permitted, but that there are some bugs with the rendering of the markers, it would seem. So, would be nice to be able to do the actions in fiddle nr 2, with the performance and visuals of fiddle nr 1.

  14. Step line connects data with vertical lines. In order to visualize climatological norm values being able to simply depict a horizontal line for one data point would be handy. Could be realized with a step line chart that hides vertical lines.

  16. Currently, the entire data series is being exported to excel instead of selected custom range by navigator. Image and pdf formats are working fine. Is there any way to export only current plotted series to excel?

  17. The general suggestion here is to manage a project using task dependencies and durations rather than dates. The simplest enhancement would be to default a task start date to the end of the dependency task. This is the ASAP assumption. It should then be possible to specify the task duration rather than an end date. Next it would be nice to specify the task start as a duration before or duration after a dependency task end date. There are other assumptions (e.g. as late as possible), but ASAP is the most common. Critical path highlighting would also be useful.

  18. As mention in the comments for "Fix spline plots" (http://highcharts.uservoice.com/forums/55896-general/suggestions/871839-fix-spline-plots-to-draw-a-better-generalized-line), sometimes the built in spline fit method is not acceptable. It would be great if there were other fit options built in (like D3: https://github.com/mbostock/d3/wiki/SVG-Shapes#path-data-generators) or allow custom algorithm to be plugged in.

  19. I plot multiple series with same Y range for data. If I use same y-axis for all series, then I have only one label displayed for the y-axis. If I use multiple y-axis, then I get redundant ticks which display the same range. Is there a way to have multiple y axis labels for each series, but to display only one ticks for y axis? Additionally, if I hide a series by clicking on legend, label for that particular series should preferably be hidden as well.
