I want people to go with another, more-active library.

Yes, we can add it. @bluegeek9, do you have time to work on it?

@bluegeek9, I see everything is green. Is there more you wanted to do on this, or is it ready for review?

Very excited to have this one in!

I'm going to close this, because I agree a custom module is the best solution for this for now. However, here's how you could do this:

MY_MODULE.info.yml

name: 'Highcharts Wordcloud'
type: module
description: 'Enables creation of Wordclouds using the Highcharts library.'
core_version_requirement: ^10.3 || ^11
package: Examples
dependencies:
  - 'charts:charts'
  - 'charts:charts_highcharts'

MY_MODULE.libraries.yml

MY_MODULE:
  version: VERSION
  js:
    /libraries/highcharts_wordcloud/wordcloud.js: { minified: true }
  cdn:
    /libraries/highcharts_wordcloud/wordcloud.js: https://code.highcharts.com/12.1.1/modules/wordcloud.js
  dependencies:
    - charts/global
    - charts_highcharts/charts_highcharts
    - charts_highcharts/highcharts

MY_MODULE.module

<?php

/**
 * Implements hook_chart_alter().
 */
function MY_MODULE_chart_alter(array &$element, $chart_id) {
  $element['#attached']['library'][] = 'MY_MODULE/MY_MODULE';
}

/**
 * Implements HOOK_charts_plugin_supported_chart_types_alter().
 */
function MY_MODULE_charts_plugin_supported_chart_types_alter(array &$types, string $chart_plugin_id) {
  if ($chart_plugin_id === 'highcharts') {
    $types[] = 'wordcloud';
  }
}

MY_MODULE.charts_types.yml

wordcloud:
  label: 'Wordcloud'
  axis: 'y_only'
  axis_inverted: false
  stacking: false

MY_MODULE.routing.yml

MY_MODULE.display:
  path: /wordcloud-example
  defaults:
    _controller: '\Drupal\MY_MODULE\Controller\MyModule::display'
    _title: 'A Wordcloud'
  requirements:
    _permission: 'access content'

  public function display() {

    // This is a container for the word cloud.
    $charts_container = [
      '#type' => 'container',
      'content' => [],
    ];

    $data = 'Chapter 1. Down the Rabbit-Hole ' .
      'Alice was beginning to get very tired of sitting by her sister on ' .
      'the bank, and of having nothing to do: ' .
      'once or twice she had peeped into the book her sister was reading, ' .
      'but it had no pictures or conversations ' .
      'in it, \'and what is the use of a book,\' thought Alice ' .
      '\'without pictures or conversation?\'' .
      'So she was considering in her own mind (as well as she could, for ' .
      'the hot day made her feel very sleepy ' .
      'and stupid), whether the pleasure of making a daisy-chain would be ' .
      'worth the trouble of getting up and picking ' .
      'the daisies, when suddenly a White Rabbit with pink eyes ran close ' .
      'by her.';
    // Convert text to lowercase and remove punctuation
    $text = strtolower($data);
    $text = preg_replace('/[^\p{L}\p{N}\s]/u', '', $text);

    // Split text into words
    $words = preg_split('/\s+/', $text, -1, PREG_SPLIT_NO_EMPTY);

    // Count word frequencies.
    $word_counts = array_count_values($words);

    // Format the result.
    $result = [];
    foreach ($word_counts as $word => $count) {
      $result[] = [
        'name' => $word,
        'weight' => $count
      ];
    }
    $charts_container['content']['wordcloud'] = [
      '#type' => 'chart',
      '#library' => 'highcharts',
      '#title' => $this->t('Highcharts Word Cloud'),
      '#chart_type' => 'wordcloud',
      'series' => [
        '#type' => 'chart_data',
        '#title' => $this->t('Occurances'),
        '#data' => $result,
      ],
    ];

    return $charts_container;
  }
}

I want to re-examine the way I'm getting array values from the ChartDataCollectorTable class.

Thank you, @loopy1492! I really appreciate the effort you took to understand the new structure and to upgrade - this really helps me (and others) focus on the current version and make that the best it can be. Thank you also for contributing the code examples!

I think this is actually handled already by the library class attributes.

I did publish the module I mentioned. It probably needs a little maintenance: https://www.drupal.org/project/charts_highstock →

Looks good - thank you!

Thank you - looks good!

I had to make an adjustment or none of the charts would show.

Thank you! I plan to review this afternoon.

Yes, no one has volunteered to work on tests, and if someone wants to, they can open a new ticket.

Unfortunately the C3.js library hasn't been updated for a long time and that version of D3 breaks some of the chart types. Billboard.js is a fork of C3.js and has additional chart type options. All users are encouraged to use Billboard over C3. Going to close this.

Thank you! I have a few things to work out like making it so that libraries required by the view can be included without bringing in all the rest of the page template. I hope to release a Drupal 10/11 version within a couple weeks.

This module did not get a modern version Drupal version. I have built a functioning modern Drupal version here (though I want to become maintainer before I invest time in finishing it completely): https://www.drupal.org/project/views_share/issues/3025018 ✨ Drupal 8 version? Active

Fixed. Sorry for the delay.

Going ahead and committing since I did observe a fix on my views-based Gauge chart, and this seems to also align with the form field types for those values anyway.

Looks great, and thanks for letting me know about the DDEV Contrib Plugin - I've been using Lando and haven't experienced that.

Thank you, @handkerchief and @marcoliver!

@loopy1492 - it's very different, but 5.x is much better and it doesn't make sense to maintain such different versions. Please help me create documentation or more of an upgrade path rather than continuing with the 8.x version.

Thank you, @diaodiallo!

@simonknight - please try the merge request (https://git.drupalcode.org/project/charts/-/merge_requests/134.patch) - I think it will fix it. Seems like the issue is just the older library was more accepting of the to and from being strings versus integers.

Sorry to hear about this, and glad you have a quick fix. Would you be willing to (on a dev instance) go to /admin/config/content/charts/advanced and select "Enable Charts Debug" (save), and then go back to your gauge chart and copy and share the JSON in the fieldset below your chart?

Do you have any custom code related to charts on your site?

Thanks!

I've updated in a new release: 1.1.2

Some people need that build step where they can have Composer pull in the libraries. You can also just place the files you need inside a properly named libraries directory. Or you can use the CDN option. There are other modules that can help install libraries, too.

I'm not sure how you got to where you are, as I tried on a fresh site and didn't experience any issues. But if you wanted to start fresh, you could try uninstalling and reinstalling Charts, you can go to /admin/config/content/charts, select your chosen charting library, hit save, then visit the "Advanced" tab and make sure the CDN is enabled.

Hope this helps!

Thanks for catching that...not sure why that happened.

It's inside the charts module: charts/modules/charts_chartjs/README.md

I've tried to replicate this and haven't been able to. Any more ideas how I can get it to fail?

For that, please check out the README.md in charts_chartjs. I'll look into this issue.

Thank you for reporting. What version of Drupal are you on? What are the steps you took before the error occurred? Did you already have charts installed?

Thank you for sharing. Is there an action item for the Charts module? I'm not using TMGMT, so it's hard for me to test this.

@gstivanin - I did some manual testing and didn't find any issues with your patch, but I also didn't experience this issue in the first place. It would help to be able to recreate the issue...can you provide specific instructions for how to do that?

I tested this and couldn't find any reason not to use it, though it wasn't needed for me either.

Thank you @ludo.r - I made a couple adjustments to include donut as well. I tested with Chart Field, Charts API Example, and Views.

I ended up making the adjustments for this in https://www.drupal.org/project/charts_highcharts_maps/issues/3511054 📌 Improve color-handling, including for grouped maps Active because I needed them to have functional manual tests.
