error reporting
Highcharts really needs better error reporting. For example, when I tried to call
new Highcharts.Chart(), I get the error "TypeError: Cannot set property 'innerHTML' of undefined". Really, I should get something like, "Missing required argument: options" or something descriptive like that. Right now I'm trying to debug this error from Highcharts: "Uncaught TypeError: Cannot read property 'length' of undefined".These problems make it seem like Highcharts is full of bugs. Instead, I'm sure I'm just using it incorrectly. The error messages should help educate me on what I'm doing wrong so I can quickly correct it.

YTD
I use Highcharts for my mutual fund company's website and it works great. However, as we only update our performance for the funds once a month the YTD as of starting 2012 is not working anymore since the values in the dataset only stretches to the end of 2011.
It would be great if you could enable a feature for YTD to only strech to the last date in the dataset. Most other funds do not update their performance (regarding their charts) more than weekly/monthly either so I am confident this will disable many fund companies from using high charts.

Add flag text to the main tooltip when aligned with the flag's date.
When i have one or more flags on highstock, i'd like the flag's text will show up in the tooltip that shows up on the charts itself and not only when pointing on the flag

Better performance
At the moment I load two very huge charts. After loading I do this:
var series = chart1.series;
$.each(series, function() {
// some stuff
});But that's very slow and freezes my browser so it takes 5-10s to load. Can you make better performance?

Create jenkins plugin to view chart in build report
The idea is to gather data during a Jenkins (http://jenkins-ci.org/) build, create a jscript and the plugin posts the chart in built report.

Zoom-slider for line and bar charts
When you have a large volume of data and the bars become cramped, it would be useful to be able to zoom in and then slide up and down to view the graph. The current zoom function doesn't allow the user to slide up or down / left or right.
Thanks for all the great work!6 votes -

Allow flags to span more than 1 date.
Allow flags to span more than 1 date.
For example, a single flag called "christmas holidays", should be able to signify that christmas vacation continued since Dec 25th to Dec31st.Currently, 1 flag can be attached to single date. I think it would be useful if a date range i.e. startdate to enddate can be specified for each flag.

Provide an option to render arrows between points instead of lines
For example, an arrow would be drawn from each element in a series to the subsequent element.

You can see for safari and IE the labels outside of the pie with an arrow and the value inside of the pie.

Use the "percent" property
Use the 'percent' property without having to stack (for instance on a basic column chart)

Enhance legend positioning
Now legend positioning is automtical and "horizontal first". I.e. when ALIGN:LEFT, legend space reserved on the left firstly and secondly I can vertically align the legend. Only center-aligned legend can be placed at bottom or top of plot area.
But my designer want to have left-aligned legend at bottom.
So it seems good idea to add legend option like
position:={top|bottom|left|right} to specify where the legend space is reserved, and use existing align/verticalAlign options to align legend inside legend area. May be ignore verticalAlign property for top/bottom position (not sure) but apply both alignment for left/right legend.6 votesSee https://github.com/highslide-software/highcharts.com/issues/3499. We have implemented this so that the layout option of the legend decides what side of the chart it should be displayed at.

Allow tooltip toggling
In current version this scenario is impossible:
1) load data
2) zoom in
3) enable tooltip (whatever that means programmatically - now basically deleting the charts element and constructing new, then zooming in with setExtremes)
4) zoom out to the full range previously loaded (that is what's now impossible)In my current project I run into this scenario quite often.
And, by the way, the Highcharts library is really good, tank you for the job well done!

Animate chart when showing fewer data points to be consistent
Currently if you add more data points and correspondingly increase the categories you get an animated transition. This does not happen however when you reduce the data points and categories. http://jsfiddle.net/mEFv7/1/
To be consistent, can we please animate both ways.

Sorted Scatter Plots
Add a "sorted" option to scatter plots that allow marking data as sorted or not ( defaulting to false ). This way, when there is a large number of scatter points, we can get the sorted performance enhancements but still get the scatter functionality ( for example, a line plot with a hidden line still has the tooltip jumping around on the invisible line ).

Optional function for yAxis to determine the column height based on its value
Though there is plotOptions.column.minPointLength property, it doesn't solve the problem completely.
Imagine there are columns which may have 0, 1, ... 1000 as values. These large values cause small values like 1 look like 0, i.e. no column is drawn.
By setting the plotOptions.column.minPointLength property to 3, causes the 0-value columns to be displayed as well.
All I want is to display the non-zero values to indicate to a user that there are some very small values.
