Does highcharts support the features provided by the following link. https://www.vizlib.com/venndiagram/. If so kindly reply.

moment.js and moment-timezone.ts are obsolete. Please remove dependencies on them. In fact, don't add dependencies, provide a callback for the needed functionality so we can choose between luxon and spacetime.

Hello.

I have a site with multiple line graphs drawn using HighStock, and a couple stack graphs drawn using HighCharts.

The users like the range selector, and would like to also use it on the stack charts.

Currently HighStock doesn't have stack charts and HighCharts does not have range selector, and so the data range is limited by the width of the page.

The totals column on a waterfall with a date is always placed on the timeline somewhere. The totals isn't actually a part of the date timeline, it's an aggregated value and should be able to be marked as such.

Basic ask is for an additional tick that is customizable that represents the placement of the placement of the connected totals column.

Problem described more fully here:
https://github.com/highcharts/highcharts/issues/10458

Here is an example scenario where this would be useful: https://jsfiddle.net/lanimelrok/6eodqvwy/

This has been asked throughout the years plenty of times. Here’s a few from a quick Google search:

There are a few suggestions of this here in UserVoice, but those seem too scenario-specific and I thought I'd just make a compilation of all of them here.

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

The boost module would be beneficial for large dataset when using the sankey chart. We are experiencing a severe degradation in performance with large datasets on this chart type

Could you please provide mode document/guideline details for integrate the Gantt chart with angular way?

Anywhere I didn't the materials.

Hello, we are your customer and urgently need Pie chart with negative and positive values

Please
You can also implement subtask for multitasking
This item is an important feature for gantt charts
The demo below does not feature subtask:
https://jsfiddle.net/user/sara_u3fi/fiddles/

Bullet chart has the option to pass a target value to the data (https://api.highcharts.com/highcharts/series.bullet.data.target). This is not possible for column or bar.

I am trying to use packed bubble chart in my angular app, its showing no error at the same time , its not displaying any thing on page, empty displayed. used https://codepen.io/anon/pen/gELMjX sample.

In most gantt charts, the ability to resize and drag in addition to the chart for the gantt charts table has also been implemented.
This means we can change the size of the table columns
We can also move the table rows with tasks

Some charts, such as heatmaps, frequently have categorical x and y axis values. Converting categories to numerical indices adds extra code and possibility for error. X-axis categorical values can be specified within an object array using the "name" field. I suggest a similar field ("yname") to specify y values by name, rather than index.

In the (highstock) navigator.series documentation there is no data property mentioned (https://api.highcharts.com/highstock/navigator.series), however in your example (https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/stock/navigator/series-data/) you provide a data attribute.

I guess you covered it with the sentence in the introduction 'Available options are the same as any series'. But the problem is if it is not reflected in the documentation it is not available in TypeScript (because I think you generated the sources out of the documentation?)

Would be great if you can adjust the documentation (and TS type for NavigatorSeriesOptions)

Hi
There are a categories in the chart for several tasks
An example in the link https://www.highcharts.com/gantt/demo/interactive-gantt is to add a task that is not what we want.
Is it possible to add and edit categories?
For example, there's a button to get a text and add to the list of categories
Thank you

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.

I have some usefull trick to center map on non empty (with some data) regions to avoid this case:
https://gyazo.com/35fd0d74d3e773f694790c5fc0c95ece

and now i can show only usefull part of highmap, by default:
https://gyazo.com/d7ca32d8ce8b1535bddd331a997c67b8

{code}
const points = this.chart.series[0];

let minX = Number.MAX_SAFE_INTEGER,
maxX = Number.MIN_SAFE_INTEGER,
minY = Number.MAX_SAFE_INTEGER,
maxY = Number.MIN_SAFE_INTEGER;

if (!points) return;

this.chart.series[0]
.getValidPoints()
.forEach(item => {
if (item['_minX'] && item['_maxX'] && item['_minY'] && item['_maxY']) {
minX = Math.min(minX, item['_minX']);
maxX = Math.max(maxX, item['_maxX']);
minY = Math.min(minY, item['_minY']);
maxY = Math.max(maxY, item['_maxY']);
}
});

this.chart.series[0].xAxis.setExtremes(minX, maxX, true);
this.chart.series[0].yAxis.setExtremes(minY, maxY, true);
this.chart.redraw();
{code}
