Don't draw chart / series if set of data is empty.
Currently I have an issue where if a set is empty, the line will still be displayed, and if all of the series are empty, a chart will display without any lines. This should be handled by default where if the series is empty, do not draw the line for it, and if all of the series are empty, do not draw the chart.

Support Title rotation.
It seems title of Highcharts doesn't support rotation. Is it possible to enhance it in future release?

Support value location for axis origin, see http://highslide.com/forum/viewtopic.php?f=9&t=15284
Since now, if you want to specify X-axis origin for column chart, you can set offset value for X-axis. But this is not usable, the offset value is just absolute points, not actual Y value. I know many popular charts support using actual Y value as X-axis origin, this should be convenient for user to specify a relative X-axis location to Y axis.

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

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/

Prevent the cursor from chaging to an I-beam when mouseover text (eg: axis labels)
By adding the pointer-events="none" attribute to the chart's <text> elements you can cause the cursor to NOT change to the I-beam when the user mouses over stuff like axis labels and such.
Little stuff likis GREATLY improves the professional appearance of the chart.1 vote -
Zoom out stepwise
Would be a great idea for e.g. all line-charts. See your friends

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.

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.

Option for tooltip to follow mouse cursor (height-wise)
Hello,
I've made some research and haven't found any option for tooltip to follow mouse cursor (height-wise). It would be one useful option if a series contains a lot of peaks and spikes or there are two series which values are very different and samples aren't aligned (time-wise). It could give one much smoother experience.

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)

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.

Color blind readability.
Support background textures on solid color UI elements like Pie and Bar charts.
Ideal solution would be angled lines in the charts for example http://www.inetsoft.com/images/screenshots/controlling_texture_in_a_bar_chart.gif

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.

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.

Allow specification of indices for series from one data array
I have data that is 10's of thousands of points per chart, so the named value pair form of the chart won't work. So I'd like to request a new feature. Where you let me use 1 or 2 indexes into the point data to define a series, but allow me to access all of the data from the tooltip. So for a line chart I would define the series by the array name, and 1 index and for a scatter chart I would define the series by the array name and 2 indices. But the this.point would refer to…
1 voteI’m not sure I get you, but perhaps you can solve your task by using parallel arrays? http://jsfiddle.net/highcharts/uBVzY/

"Inverse" step line option
Current step line chart plots the horizontal line first, then the vertical. "Inverse" option would result in the vertical line plotted first, followed by the vertical.
