Parallel coordinates chart performance improvement, boost module support
https://www.highcharts.com/docs/chart-and-series-types/parallel-coordinates-chart currently isn't supported by the boost module.
This chart is performing poorly with large dataset, we would really appreciate the performing boost.

cursor:'pointer' on every point
Let specify the cursor:'pointer' on every point, not only on entire series or in the plotOptions object, thanks.

api hook for missing data
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?

Allow users to hit Enter to change date/time range
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.
0 votesWe currently use the input box’s onchange event. Turns out that Chrome and Firefox already trigger the event on Enter. IE8 however fails to change the ranges on Enter.

support more or custom spline fit algorithms
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.
0 votesActually there is such a method, getPointSpline. It computes the line segment from one point to the next. It takes arguments for the whole segment, the point and the index, so you can add the surrounding points to the calculation as well. See http://jsfiddle.net/highcharts/6sQjJ/.

A way to combine y-axis labels
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.

add useExternal setting to tooltip config
Add a new useExternal setting to the tooltip config which when set to true, would prohibit the tooltip from actually being shown in the chart, but it would still allow the tooltipRefresh event to fire. By allowing the tooltipRefresh event to still fire, an external non-highcharts tooltip can be created using the information passed along in that event. From looking into the code, this can maybe be done in the Tooltip refresh method?
[code]
// update the inner HTML (add the useExternal check here)
if (text === false || tooltip.useExternal) {
this.hide();
} else {
…// show it if (tooltip.isHidden)0 votesThank you for your request.

Patterns in venn diagram
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.

Double logarithmic axes and draggable points
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.

step line without vertical lines
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.

Export custom range data (through navigator) to excel
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?

Gantt Task Dependency Enhancements
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.
