reversing selected colorscheme and maximizing contrast in highmaps
We have recently implemented highmaps on our site and added features to let content creators select different color schemes when they create a map.
But what they are missing is two things: a option to reverse the selected colorscheme from dark to light or light to dark.And a behavior change in highmaps when using the defined colors, so that if the map has fewer data classes than the number of defined colors, only the colors with highest contrast between them should be used.
example: if only two data classes are defined, only the lightest and the darkest color should…

Rangeselector with numerical x-axis
Rangeselector is great, but I have only seen it with dates on the x-axis. Is it also possible to have numerical values instead?
I would expect it to be relatively straight-forward. If not, is there a reason for not supporting it?
Thanks!
6 votesIt’s already possible, but not very intuitive, since Highstock is all about time-based data. The trick is to set the button type to “millisecond”, which represents one axis unit: http://jsfiddle.net/zgLdjk6k/

Highcharts wordcloud: Group words in sections and show words having maximum weight in each category with relative font sizes
https://www.anychart.com/products/anychart/gallery/Tag_Cloud/State_of_the_Union_Address_Most_Used_Words.php
Refer the image in the above link. The image shows words grouped in 3 categories: Barack Obama, George Bush and Ronald Reagan. Each of these categories have a word with maximum frequency – I (70%), will (49%) and will (65%) respectively. Thus the font sizes of maximum frequency words are shown relatively.
I have tried following 3 examples:
1) Render three wordclouds in a one chart: jsfiddle.net/znm6f89r/8 - but still, word weight is based on the size within the series.
2) Define custom placement strategy: jsfiddle.net/znm6f89r/28 - but labels may not be within the column.
3) Using 3 series…12 votes -

Allow option for use of Voronoi diagrams by tooltips
For the tooltips, the hover over are isn't very user friendly.
For example, using the closest point on the X-axis in a chart rich in data points is hard to get the exact point of interest. Usually these points occur where there is a distinguishing feature which Voronoi diagrams excel in. Such as a spike in a line diagram.
Even when there is no feature to focus on, the Voronoi diagram will have effectvily the same interaction as the current method.

add a property for keeping the font-size fixed on svg files while resizing it
I would love to have a property fontresize: boolean like
title: {
text: 'Highcharts Header',
style: {
fontSize: '48px',
fontResize: false;
}
}
for all Texts at the charts or may be also on generall property which works on all texts.
This property (set on false) should avoid that while resizing the svg-file the size of the text is being resized too.3 votes -
Set initial state for (custom) buttons before drawing
As I explain in this SO question https://stackoverflow.com/questions/51282216/set-initial-state-for-custom-buttons-before-drawing-highcharts , I need to create custom buttons with an initial/default state (disabled mostly).
Right now I use a callback function with setState (thankfully this doesn't redraw the graph, therefore we face little to no performance impact) but it I believe it could be a nice feature
