Adding a chart type: line chart with irregular intervalled x-axis.
For example, if you have 4 decadal data points for median income (e.g. [1980, $35,000]; [1990, $40,000]; [2000, $50,000]; [2010, $49,000]), and you want to show this data in a line along with annual data for 2011-2014 (e.g. [2011, $49,500]; [2012, $49,750]; [2013, $49,900]; [2014, $50,000]), if you use the current line chart option, each of these years will be evenly spaced on the x-axis but such spacing is not proportional the number of years between each point and I would like to see a line chart option it was.

Insert series at specific index
Similar functionality to addSeries except with an index parameter so you don't have to always add series to the end of the array.

Built in CSV support/Separate data from config
Please add "native" support for data as CSV. Partially in docs you describe how to make use of CSV data, but I think this is just too inconvenient. A nicer approach would be to have the API separate the "data to display" from the "configuration of a chart", where the data would be as CSV and the configuration as JSON or XML. Take a look at AnyCharts (or better AnyStock) for a very nice API that does this.

Cursor X Value and Event
Using a cursor line following the mouse, not points, would be very useful know current cursor value (X axis value) to allow us to interpolate Y values and a way to set a JS method that will be fired on cursor move.
Is very common a table with the columns (Timestamp and Value), but in some analisys, is very useful "see" the value between 2 points. The value between this 2 points doesn't exist on dataset, but can be interpolated. With the current X value of cursor and a event will allow us to develop a JS interpolation method.15 votes -

Position of axis
I would like to be able to choice the position of my axis, for logarithmic chart or not, like this image : http://img15.hostingpics.net/pics/881099axis.png
Indeed, I need to split my chart in 4 part in taking the x-axis and the y-axis in a exactly point.
Have you got a solution or is it possible to take this in the roadmap?Thanks
15 votesYou can position your axis absolutely through the offset option: http://api.highcharts.com/highcharts#xAxis.offset.
Combined with chart.marginLeft, chart.marginRight etc., it provides absolute pixel positioning control. -
Tooltips should show the serie symbol
Right now the tooltips have this default for the pointFormat option:
<span style="color:{series.color}">\u25CF</span> {series.name}: <b>{point.y}</b><br/>.
\u25CF is always a circle, instead of matching the serie symbol, like it does in the legend.
This is very important for charts with many series, when using a shared tooltip. Especially if you are color blind.

Provide control over X axis point in dataGroupng
Grouped points are aligned to the left of the group by default when dataGrouping is applied.
smoothedoption allows the data to be shifted to the middle of the group.Would be great to have option to get grouped points with X coordinate of rhe most right point of the group.

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)

Datapoints provided in the series, if NaN, kill the entire chart.
NaN as a datapoint should be gracefully handled, rather than the chart showing no data at all. see this example http://jsfiddle.net/RL6UY/

Limit the max number of ticks to prevent the browser from being no response
Small value of the "tickInterval" option results in too many ticks that cause the browser to be unresponsive. (To reproduce by changing the series data from "500" to "10000" at below jsfiddle link.
So it would be helpful to have the max tick number as a cap.
If the data range is too big and tick interval is too small which makes the tick number too big, then the max tick number is used to prevent the unresponsive behavior.14 votes -

Horizon charts
add horizon chart capability to highchart, cause better understanding of differences between multiple series at the same time and of course, we could use our screen more better than before.
like what we have here:

maxRange for axes
The option
minRangeallows it to determine the minimum extent an axis will display (for example if the user zooms into the chart). It would make sense to have amaxRangeequivalent, particularly for simulation data where 'optimal runs' often increase exponentially. See also http://stackoverflow.com/questions/17287920/14 votes -
Can we have a timeline chart which is absolutely business oriented
Can we have a timeline chart which is absolutely business oriented? Basically Business team here at my organisation would like to visualize charts based on fiscal year instead of calendar year. For example
i. Fiscal year starts on 1st of July every year.
ii. Aggregating data based on Fiscal quarters
iii. Flexibility for aggregating week data as per the selected day(In our case we aggregated week data from Saturday to Friday)
iv. Formatting x-axis labels as Fiscal years/ Quarters/ Months/ Weeks not just calendar year/ month / week14 votes
