columnrange - use different colors for "pos"/"neg" values
the functionality provided with this new type is very useful. The given example (Temperature-Range) is OK, but indicating the columns relative to a threshold (value minus threshold) might be another good application for this type.
1 voteNegative color and zones are supported by column range.

Re-draw only one bar in a bar chart
Can you implement redrawing only one bar in a bar chart when the value for that bar is changed?
I am trying to use a slider to change a value in a bar chart. However, when the value is changed, the whole chart gets redrawn, not only the part that changed. Here is what I am trying to replicate - http://www.budget.msu.edu/budget.swf. I know this is Flash so it might be too slow in JS, but I think it is worth the effort.
Thank you.

Right now Highcharts can run locally but the themes will not work if high charts.js is linked locally.
1 voteThis works correctly now.

Add dual y-axis to highstock
Highstock allows for multiple series but you can only work with one y-axis. When plotting 2 series with different y-values range, the single y-axis does not scale for both series. Having dual axis will allow a scale for each series.
1 voteDual axis is already supported: http://jsfiddle.net/highcharts/jHjZF/

Ability to create expanded view when clicking on a point
When clicking on a point it opens up an expanded window that displays more information about that point. similar to a drilldown but not a chart, more of a list.
1 voteYou can build this using the Point.click event. Extra information can be added to the point config, and displayed the way you want, for example with jQuery UI or Highslide. Check out http://highcharts.com/demo/line-ajax.

return the calculated intervals for timeline axis
Now the axis object has something called categories, which will show for regular axis what are the intervals. For timelines though we set in the data using timestamps and you dont know exactly what timeline is generated. And if you zoom in then the timeline is actually changed ( you can control this a bit with the maxZoom variable).
Example. I insert as data 3 values in a timeline. We can get the min and max of the timeline, but not the step. And min and max are relative to the state of zoom, not absolute so if I want…
1 voteThe tickInterval option, http://api.highcharts.com/highcharts#xAxis.tickInterval gives you a fixed tick interval.

set yAxis min 0 as optional for column series
i would like to set one series as column series in multi series chart , however this seems to force the xaxis min down to 0, I cant find and easy switch to have it autorange like a line series.
1 voteSee http://api.highcharts.com/highcharts#plotOptions.column.threshold. Setting the threshold to null has the effect you are looking for.

Positive color
Since the release of Highcharts 3.0 we have the threshold option and negativecolor. It would be nice to be able to have a positivecolor also and color anything above the threshold instead of only values below the threshold.
For example right now i have a different color for each serie. And i want to use the threshold to change the color if above a certain threshold. Right now this means the color for each serie becomes the same for anything below the threshold.
1 voteClosing due to lack of activity. Also, we have now support for color zones.

add button on highstock so we could hide series like what we could on highcharts
it would be great if we could hide series in highstock like highcharts. it helps visualize the data more better and we could understand the differences between series much better.
1 voteJust enable the legend then place it where you find best

Add width (and/or minWidth and maxWidth) properties for yAxis.labels
This would simplify stacking timeseries charts, as described in an earlier question: http://stackoverflow.com/questions/15582294/fixed-y-axis-label-width-in-highcharts.
I'm familiar with the approach using multiple plot areas (as seen in http://jsfiddle.net/markwatson/D7rBR/), but it seems like stacking multiple charts in the same time range, and aligning the data consistently seems very reasonable to me.
1 voteWe now support setting label width. Overflow is handled through text-overflow: ellipsis.

Support for multiple subtitles, or support useHtml option on export.
I need to have multiple subtitiles at the top of the chart. Or multiple lines of sub titles. I can't use html formatting with a "<br>" or "useHtml:true" because this does not seem to work in the export.
Can you add support for either:
a) Multiple lines of subtitles (that look the same in the exported chart)
or
b) Support the subtitle useHTML:true along with html formatting in the export of jpg, png, etc...1 voteBut line breaks do work in export as well: http://jsfiddle.net/highcharts/RkCWk/

.net Library for highcharts
it will eb great if there is a .net library for highcharts which allows us to write code in c# instead of java script.
This will simplify the coding and handling special cases.

Donut Chart - How to reducte the data label pointer width ?
Hi, am using Pie chart. I want to reduce the width of the data label connecter and also i want to remove the space just before the data label value as shown in the following link.
https://docs.google.com/file/d/0B2Xipj7JTuYhdkctRHo3LWtHeTQ/edit?usp=sharing
My intention here is, to display the values(data labels) with in the area. Is there any way to decrease the connect width & remove the space before the value?
Or is there any other way to display the values within the charting area?
Thanks
1 voteTo put the data labels inside the pie, see http://api.highcharts.com/highcharts#plotOptions.pie.dataLabels.distance

Can Highcharts dateFormat support fractional seconds?
I need to display time as HH:MM:SS:sss. 2.14 doesn't seem to have this capability. I did an exhaustive google search to find out if any version of highcharts has this and I haven't been able to find it. Is there support for this in any version? If not, will there be?
1 voteHighcharts does have milliseconds display. The format you are looking for is “%H:%M:%S.%L”. See http://jsfiddle.net/cqxPq/.

dynamic new Series adding at different points
When we try to add new series at later time (already a series is running), the new series is getting added up from beginning where series1 started. Is there any alternate way to avoid this probelm. The series2 should start from time I started.
1 voteSure, you use either the pointStart option or you can set an X value for each data point.

Add an ability to show error bar in legend
Currently the error bar does not show up in legend. Error bars can be used to show various data (e.g. blood pressures) and we need a way to show it in the legend.
1 voteTo enable the error bar in the legend and preserve the link to the parent series, just set showInLegend to true: http://jsfiddle.net/highcharts/158nvhe3/9/
The error bar is linked to “:previous” by default. By nulling this option, it appears as a standalone series. http://jsfiddle.net/highcharts/GpPHq/.
