id and getPointsByCategory
- please expose the 'id' attribute of series. highCharts and highStock can use chart.get(id) to get an series/axis/point. point and axis and explicitly get and set an id attribute except series.
- add function 'getPointsByCategory'. I am using a column chart and I have to get points in specific column, but I have to do it myself because I can't find a function to do it.
best wishes for a more perfect highCharts. Thank you very much.

reanimation: Animate multiple time with setting property
It would be better if we can set the number of times the graph would animate. This would be most useful in case we have graph placed in heavy loading web page, where before the whole web page gets loaded, the animation of the graph gets completed. so that user is not able to see the graph animation. user just see the graph which is static and not animated.

associate rangeSelector with a specific xAxis (in Stock)
Allow the rangeSelector options to be associated with a specific xAxis for the Stock product.
If more than one xAxis is present the rangeSelector does not seem to work. I would like to tie it to the xAxis used for the navigator.

Graph Replay User Interface
I know the current Highcharts support animation when updating series data. However, I think Highcharts would be really useful if it can provide a way to play, replay, step forward, step backwards kind of interface.
Let say I have a time series chart, then I have configured the chart to only display 10 data points with spline. Then load the series of data containing 100 data points. When user clicks play, it will play through the data trend.
Same thing can apply to bar and pie charts. But ultimately, I think the most interesting one is using with Heatmap.

useUTC as a configuration per chart
I have an application that uses UTC in some graphs and non UTC time in other. It would be great to have is as a configuration.
7 votesHere’s a plugin that implements this by setting the global useUTC setting on chart init and on mouse over: http://jsfiddle.net/highcharts/auvsV/

Customising legend symbols
It would be great if we could customise the legend symbols. I managed to drill down and find the borderRadius in the main js file but would be good if this was an option like in the main legend box...
Also if we could replace the symbols with images that would be great too. ie we could have flags for country data etc.
if (simpleSymbol) { // bar|pie|area|column
legendSymbol = renderer.rect( (symbolX = -symbolWidth - symbolPadding), (symbolY = -11), symbolWidth, 12, 0 // affects border radius of legend symbol ).attr({ //'stroke-width': 0, zIndex: 3 }).add(legendGroup); // draw the marker }52 votes -
Allow images to be included in axis labels
Provide some way of including an image in an axis label. For example, I may want to prefix the axis labels with an icon.
I've tried including HTML in the axis label and using axis.labels.formatter to add image HTML into the label. Neither worked. I've seen reference to using renderer for doing this, but I haven't been able to find an example.
21 votesThe key is setting useHTML to true: http://jsfiddle.net/highcharts/8FSp6/.
Here’s another approach, allowing true SVG images: http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/studies/axis-label-images/. The advantage of using SVG is that these images willl be visible in the exported chart as well.

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.

series.compare should switch to absolute values for single series in a graph
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.42 votes -
Real-Time Smooth Scrolling
While Highcharts Stock supports dynamically updated data, the new data points are applied in a jerky fashion. It's becoming easier to build real-world real-time data applications: it'd be great if HighCharts Stock could handle these updates in a smoother fashion (similar to Smoothies http://joewalnes.com/2010/08/10/introducing-smoothie-charts/).
Related forum post: http://highslide.com/forum/viewtopic.php?f=9&t=12462&p=55471&hilit=real+time#p55471
6 votesYou mean like we do in Highcharts: http://www.highcharts.com/demo/dynamic-update.
The Highstock charts generally consist of much more data, so currently we have disabled animation because it didn’t perform good enough.

Bar w/ Neg stack from opposite ends of Y-axis
Same as Bar with negative stack but instead of data points starting out from the center and going outwards towards the left Y-axis and right Y-axis, have data start from the left and right Y-axis but moving towards the center (with an arrow for each bar)

Ability to use image as bar chart
Each column could be constructed with a series of images. So for example if I wanted each bar to be made up of a column of little blue squares, I could specify the image to use and the chart would use that to construct each bar.

Stacked area (spline etc) in irregular datetime series
When you create more datetime irregular series, by now only the same datetime values are used to create the stack, resulting in a correct-but-ugly graph.
327 votesWe have done improvements in this behaviour in Highcharts 3.0. See http://jsfiddle.net/highcharts/QuteB/. Would you consider this case solved?

Add mouse events for chart axes
I need to be able to capture mouse events on axes - primarily hover (mouseenter/mouseleave) and click - so that I can expose axis options in a user friendly way.
I suggest adding these events to the axis definition, much the same way that series and points are done. Also need to be able to identify which axis was clicked (just the id is fine)
