Crossfilter
Hi, wanna know if it's possible to add Crossfilter: http://square.github.com/crossfilter/ functionality in Highcharts.
At this moment, samples of crossfilter are using d3.js .
I'm using Highcharts because it's awesome BUT Crossfilter yet.
Can someone help me about this, please ?
Best regards.124 votesDashboard functionality is supported by Highcharts. The concept is just to add one chart to each div in the layout you want for a dashboard. Actions on one chart are captured by event handlers, and used to update other charts.

An option for preventing a chart from interfering with iPhone scrolling
Charts capture scrolling events on an iPhone or iPad, making scrolling the page by flicking on the chart area impossible. An option for changing this behavior would be desirable.

3 Colored Background
Provided a colored background for target values.
When we measure, ultimately we want to compare these measure to a target value. Target values should be a color option in the background (similar to the speedometer gauge). The number of colors up to 3 (R,Y,G) should be driven on the number of ranges for the target value. Thus 100 to 95 (Green), 94 to 75 (Yellow) and 75 and below (Red) give us 3 colors for the background. There needs to be an option to direct the value as ascending or descending (i.e. up is good (Revenue) or up is bad…5 votesThis is done with plot bands.

Wind Direction Gauge
Would like to see a Wind Direction Gauge (360) + N,E,S,W etc.
Like on this image: http://postimage.org/image/vnpx7frbj/
I cannot reproduce this using a simple gauge using highcharts since the y axis labels do not align correctly.
Also with a simple gauge it is not possible to change the arrow, so one does not know if the the wind is coming towards the arrow or going away from it.3 votes -
return the calculated intervals for timeline axis
Now the axis object has something called categories, which will show for regular axis what are the intervals. For timelines though we set in the data using timestamps and you dont know exactly what timeline is generated. And if you zoom in then the timeline is actually changed ( you can control this a bit with the maxZoom variable).
Example. I insert as data 3 values in a timeline. We can get the min and max of the timeline, but not the step. And min and max are relative to the state of zoom, not absolute so if I want…

add button on highstock so we could hide series like what we could on highcharts
it would be great if we could hide series in highstock like highcharts. it helps visualize the data more better and we could understand the differences between series much better.
1 voteJust enable the legend then place it where you find best

Up and Down Border Colors on Candlesticks
You added upColor along with regular color on Candlesticks - this is a great start. However, almost all Candlestick charts offer differing border colors as well, an upBorder and downBorder if you will. If you would add this so we could base it on a real stock chart's open, high, low and close this would be a TREMENDOUS improvement.

Positive color
Since the release of Highcharts 3.0 we have the threshold option and negativecolor. It would be nice to be able to have a positivecolor also and color anything above the threshold instead of only values below the threshold.
For example right now i have a different color for each serie. And i want to use the threshold to change the color if above a certain threshold. Right now this means the color for each serie becomes the same for anything below the threshold.
1 voteClosing due to lack of activity. Also, we have now support for color zones.

set yAxis min 0 as optional for column series
i would like to set one series as column series in multi series chart , however this seems to force the xaxis min down to 0, I cant find and easy switch to have it autorange like a line series.
1 voteSee http://api.highcharts.com/highcharts#plotOptions.column.threshold. Setting the threshold to null has the effect you are looking for.

Parallel Coordinates
Add a parallel coordinates chart. For example: http://exposedata.com/parallel/
or http://en.wikipedia.org/wiki/Parallel_coordinates
This would allow for quicker analysis of data typically found in tables.

Add gauge properties for handling values outside Y-axis range
When a gauge gets a value outside the Y-axis range, the needle keeps rotating. It then looks as if another value is indicated.
Example: the Y-axis is from -50 to 50. When an value of -75 is specified, the needles points to 48, which is invalid.
I cannot resolve this by modifying the "-75" value to "-50" because of the value label and tooltip, which must show the correct value of -75.It would therefore be better for the needle not to move beyond the Y-axis scale. Or only a few degrees as an indication that the actual value is…

When Scrollbar is enabled using Highstock.The Default position of scrollbar is to right. As in the fiddle
http://jsfiddle.net/highcharts/fj6d2/
scrollbar position is right by default
When there is large data, we need scroll bar to be in left position.3 votesYou control that through xAxis min and max: http://jsfiddle.net/highcharts/fj6d2/1863/

Percentage in pie legend
Lots of pie charts have the percentage value next to the name in the legend. Today you can only get the name and y-value in the legend's labelFormatter. It would be really great if you could add percentage as well, like the tooltip's formatter.

Reverse scale option for ranking - 1 highest to x lowest (eg. 1 = First, 10 last)
Currently there is no way to have a scale where lower numbers have the largest bar (i.e. reversed/inverted bar widths.)
This is essential in situations where you are ranking a number of categories and 1 counts as the winner or first place.
3 votesA combination of a reversed Y axis and a series threshold does the trick: http://jsfiddle.net/highcharts/ya2xz/

Re-draw only one bar in a bar chart
Can you implement redrawing only one bar in a bar chart when the value for that bar is changed?
I am trying to use a slider to change a value in a bar chart. However, when the value is changed, the whole chart gets redrawn, not only the part that changed. Here is what I am trying to replicate - http://www.budget.msu.edu/budget.swf. I know this is Flash so it might be too slow in JS, but I think it is worth the effort.
Thank you.
