Re: change the color of a set of points by index array

This happens because some points that are hidden behind others are not added to the points array in the series, optimizing memory usage and performance. The default usage is of course a two-dimensional array, but unfortunately a bug related to the lack of interpretation of `colors` in `keys` makes i...

Re: Angular load solid gauge module fails

Hello emre, Welcome to our forum and thanks for the question! Since v12, the module will not return a factory function, so this will cause an error. Instead, import it like this: import Highcharts from 'highcharts'; import 'highcharts/highcharts-more'; or with es-modules: import Highcharts from &quo...

Re: Some Issues with DataGrid

Hello,

Thank you very much for the input!

It's a bug, I reported it here: https://github.com/highcharts/highcharts/issues/22301

We will fix it in the near future, we're mainly focusing on refining styles and fixing these types of bugs now.

Best regards,

Re: change the color of a set of points by index array

Hi,

You can use e.g. console.time to measure this.

Turbo off: https://jsfiddle.net/BlackLabel/uj7a205m/
Turbo on: https://jsfiddle.net/BlackLabel/cbry8v5t/

In my case, there isn't much difference visible.

Re: Treemap Styled mode

Hello, thanks for the question! The easiest approach would be to define CSS classes with that colors and applying them to the points, like in the demo below. Demo: https://jsfiddle.net/sa04jokb/ If that's not enough, let me know, I'll try to find a more customized solution for your use case. Best re...

Hello! Welcome to our forum and the world of Highcharts. Let's tackle your questions one by one: 1. ​Smaller Time Aggregations:​ Highcharts Stock can indeed handle smaller time aggregations like seconds or even tick-level data.

Re: React + JavaScript + ESM: Issue with Custom Dashboards components

That's good to hear that it resolved the problem!

I raised a ticket to fix it in the docs, to avoid misleading in this aspect. Thanks for your input, it's really valuable!

Re: React + JavaScript + ESM: Issue with Custom Dashboards components

Hello, Thanks for the question! As far as I know, no custom adjustments are required. It looks like .catch is being called somewhere on an object that is probably not a Promise. `load()` is an asynchronous method, although I see that it is not marked as async in the documentation. If you add `async`...

Re: change the color of a set of points by index array

How can I bump it? The issue was closed. It's not closed. You can just write a comment asking for updates. In your example the Boost is still enabled, but the Turbo mode is not. Is that correct? Yes. As is explained under the ticked by Hubert, point.color declared in an object works correctly, but ...

Re: change the color of a set of points by index array

Hi, When it comes to the boost module, there's one bug, requested here: https://github.com/highcharts/highcharts/issues/21032 This causes the color specified in keys to not be taken into account in boost and must be specified in the object. You can bump the topic or ask for the prioritization. But y...

Re: change the color of a set of points by index array

Hi,

I'm still not sure if I get your question.

You can update it like that: https://jsfiddle.net/BlackLabel/nakof9ey/
And it's quite an efficient way.

Hi Radion, Thank you for your question. Creating a custom algorithm to meet your requirements (dividing the chart into two sections, maintaining minimum dimensions for smaller elements, and proportionally scaling larger ones) is quite complex and would take a significant amount of time to design and...
