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/).

The Highstock charts generally consist of much more data, so currently we have disabled animation because it didn’t perform good enough.

Chart title should render in front of all other chart elements
The chart title is rendered behind chart data and grid lines, causing data points to obscure the chart title.
When rendering to an interactive web page, it is possible to work around this by bringing the title toFront() after load.
However, this is impossible when using export, since it creates a new copy of the chart and then exports that.
Thus, the chart title should render in front of other chart elements, by default or as an option.

Write all or some of the x-axis items according to the chart area size or rotate them when there is no enough space to write them
Sometime there is a lot of category (x-axis) that can't fit inside the chart, so to solve this we can do:
Rotate them, and/or
Write some of the x-axis items according to the chart area size1 vote -

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.
