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 -
Link a PlotLine to a Series
I cannot find a way to link a PlotLine (an average line, for example) to a specific series. I would like to be able to toggle the visibility of such a line with the visibility of a series. There's currently no way to do that easily, and I think that this would be a useful feature for a lot of scenarios.
3 votesYou can link them together using event handlers like so: http://jsfiddle.net/yb18evpt/

Add dynamic data update for iOS wrapper
For iOS wrapper there is no way to do
data.addPoint(...). The only way to do a dynamic chart is resetting data when new points become available.
Would be nice forHISeriesto contain methods such asaddPoint()anddata.update()for data changing. Also animation shall work on such operations.3 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.

scientific notation
It would be nice to have a default formatter for displaying numbers in scientific notation
3 votesHere’s an idea of how to add a format for scientific notation:

Alternatively, Number.toExponential can be used inside formatter functions.

Hello Highcharts team,
We need USA country map drill down to a specific city or location level.As per the questions in search forum we searched USA city level coordinates data in the following path and not able to find it.https://code.highcharts.com/mapdata/
It would be helpful to us if you people provide us Geojson data to specific city or location level in USA or adding a new feature to drill down data as we doing it from state to county level drill down.

Panes instead of yAxis
I've seen the demo of using yAxis as if it was a separate pane, but it's basically just faking it. I'd like to have actual separate panes in the chart, so that I can have a mix of different yAxis series exist inside each of those separate panes.
like:
Pane1 : holding 2 line series with separate YAxis because of value range
Pane2: holding a column series on its own yAxis, and a line series on a yAxisinside 1 chart, not multiple charts

Native support for vertical mouseover "scanning"
Unsure of the terms here, but currently the only way to make the mouseover scan vertically instead of horizontally is by inverting the chart. This however inverts the Highstock navigator as well, making the chart I need vertical mouseover scan for look strange compared to the other charts on my site. The solution suggested by highsoft support is to make a second chart which resembles the navigator , but is too time-expensive to impement on every chart on my site..
So, I either wish for an option to flip the mouseover scan without inverting the chart, or an option to…

Allow zoom using just the keyboard
I've written some script to allow for this at least in line charts only allowing zoom on xAxis. The code isn't the best, but it works, would be better if it was in the API.
$("#container").bind('keydown', function () {
let chart = $("#container").highcharts().xAxis[0];
var min = chart.getExtremes().min;
var max = chart.getExtremes().max;
if (event.keyCode == 107 || event.keyCode == 187) {
//zoom in
min++;
max--;
}
if (event.keyCode == 109 || event.keyCode == 189) {
//zoom out
if (min > chart.dataMin) {
min--;
}
if (max < chart.dataMax) {
max++;
}
…} if (event.keyCode == 39) { //right arrow if (max3 votes -
Download as CSV Support more than 100k-300k point
Once, there is more than 100k to 300k data point, its unable to download as csv.
If we are using array object [{x:0, y:1, a:1,b:2,c:3}...], less than 80k point, its will shown out Failed- Network Error.It looks like it is related with the length of data URL that is used to build CSV file. In case there is a huge amount of points, its length is too long. It looks like some browsers have limitations for data URL lengths.

Validate chart options
Chart options strongly depend on chart type and other options. For example, ticks on x/y axis. Depending on what type was chosen (linear, logarithmic, datetime or category), ticks are configured differently.
And I really suffer when I read docs and don't clearly understand which properties work with others, and which are useless together.
I suggest you to update docs, or implement chart options validation, or even provide us some external service to check, if given options are valid. In ideal world, if options are not valid, it would say why and maybe suggest something.
3 votesThanks for requesting! This kind of validation could be added to the debug module.
We do try to add information about conflicting options in the API docs however. Are there any specific cases that we failed to mention?

Add an option to the navigator to behave like the range selector
I would like to have an option in the navigator that avoid filtering the series on the main chart. This option will allow the navigator to behave as the range selector.
At this moment, the navigator can be easily customized with the JS API and CSS; my goal is to style the navigator to be a horizontal bar with handles that can be used as the range selector.

Even something as simple as just providing an additional object for each category that contains what points it has from each series.

Define two font colors for datalabels depending on inside or not
In a bar chart I found no way to define if datalabel is inside or outside of the bar. Highcharts computes this depending if the text fits inside or not.
When you have a white background and a colored bar, and you want to have the complementary color for the text depending on inside or outside of bar there is no way to find out which color to set, because highcharts positions the text dynamically. e.g. on changing browser size, the position can swap from and to inside or outside of the bar.
Sample: some labels are inside and some…
