Improve series highlight on legend hover event (by dimming other series)
It would be useful if you could improve the series line highlight (or equivalent on other chart type) on legend hover event.
Following what is currently achieved on hover state by default, where it highlights the series line by adding line width, it should be possible to dim or gray out the other line series in the graph.
This can be easily done by using events on legend items hovering: http://jsfiddle.net/vitorbarbosa/qpByN/
however, it would be nice if it was implemented natively and for other chart types.17 votesHere’s a plugin that works with columns as well: http://jsfiddle.net/highcharts/Ha3Wr/
It works by setting the opacity on the group element. I don’t expect it to work in legacy IE though.

Currently you can do this by removing the band and adding a new one with another color.

Auto-PlotLines for Min, AVG and Max values
Auto-Plotlines for aggregate functions like Min, AVG and Max based on the series values.
This would be accessible via the series or plotline objects and would draw the lines automatically (ui default properties for each plotline defined as well and not null) for the aggregates on the values of the series.

Make plotLines work without explicit width or color
Most things in HighCharts have smart defaults, so unset options will do something reasonable. But plotLines is not this way: if the user does not explicitly specify a width and color, no line will be drawn (and sometimes a JS error will happen).
Example which works but includes comments on how to easily break it: http://jsfiddle.net/LKayp/
I think plotLines (and addPlotLines) should default to a reasonable width and color, just as regular series lines do.

Column chart: gradient fill per column over height of chart
I'm trying to create a column chart showing advice based on weather data. Values are between 0 and 2. Based on the value the height is determined, and currently a singular color. I'm trying to modify this to have a gradient range for top to bottom of the chart, not as a background. Colors should start at the bottom showing red, showing a gradient to yellow (at value 1) and green (at value 2). However, I want the gradient shown even if the value for the column is say 0.615, which would need to show a gradient past halfway, still…

Support for (non-breaking space) for legends, labels and categories
It would be great to control line breaks completely using non-breaking spaces ( ), <br> tags and soft hyphens ().

Columns for tooltip
It would be nice to be able to specify the number of columns in the tooltip. For instance, I have a chart with 44 line series, 22 each for two different data sets. This makes the tooltip too long for the chart area. If I could specify two columns, it would fit fine, and be easy to read.

Step Position ('on', 'between')
I'd like to specify a stepPosition (such as 'on' or 'between') when step: true. Currently the step always occurs on the actual data point. I'd like to be able to have it step before the data point, so you end up with a plot more similar to a column chart.
My example is that I have an area chart with overlapping series, but I need a step chart, because I'm representing a fixed number of reads at specific loci on a strand of DNA.
7 votesActually we just implemented this. See http://jsfiddle.net/highcharts/vQS2n/. It will be released with the next maintenance.

Multi-color data series
Sometimes we want to see more information in one data series, so a single Y value isn't enough. For example, I want plot a stock series where Y represents price and color/brightness represents the volume.
I started a discussion on this topic in the support forum:
http://highslide.com/forum/viewtopic.php?f=12&t=22326&p=87651#p87651

Complete auto scale (auto resize) option for charts
When resizing a chart, it would be great if the all chart elements (titles, labels, legend items, axis, all fonts) auto scaled appropriately with the chart.
This would apply not just to expanded/contracting the height and width area of the chart, but also when using the zoom feature.
Thanks.

Justified text alignment in legend box
I have the following in a legend:
labelFormatter: function () { return this.name + " - " + this.value; }
That looks fine, except, I want to remove the " - " and have all the values aligned to the right in their line.
