This module adds chart and table visualizations to your DKAN datasets. It displays these visualizations on a dedicated "Visualization" tab for each dataset or can be accessed directly through a URL.
Chart/Table visualization for DKAN Datastore API
Installation
DKAN
only version 1.x
Take care to enable the datastore submodule of DKAN.
the datastore module needs to be enabled beforehand, it will not get automatically enabled due to https://github.com/GetDKAN/dkan/discussions/4149
clipboard.js
The clipboardjs module is used. You need to take care of installing the clipboard.js library. See README
Configuration
Number format settings
You can provide a decimal separator and a thousands separator by config setting.
$config['dkan_chart.number_settings'] = [ 'decimal_separator' => ',', 'thousands_separator' => '.', ]
The decimal separator will be switched to full stop. The thousands separator will be removed.
This may help outputting the visualizations.
Datastore rows limit
DKAN defines a datastore rows limit setting to control the maximum number of rows the datastore endpoints can return in a single request. This is set to 500 by default. DKAN chart operates based on this setting. You can increase this setting at admin/dkan/datastore if 500 does not suit your datasets.
If possible increase to the maximum number of rows your datasets provide. But setting too high can lead to to timeouts or memory issues.
Features
Provide chart visualization features for data from DKANv2 Datastore API, currently based on chartjs
There will be a tab "Visualization" on each dataset node that has distribution/s in the datastore. On this tab different visualizations can be arranged for this distribution.
If you do not see the tab (like when using DKAN react frontend) you can directly access the visualization page via node/ID/visualize. You may also need to set permissions: admin/people/permissions/module/dkan_chart
Using Choices-js for some multivalue select fields in the UI of the visualizations (for the time being, may change to Select2 or Selectize later if necessary. Choices-js does not need jQuery, which makes it kind of sympathetic as Drupal is also slightly moving away from jQuery).
Feature Spreadsheet tables
By enabling the submodule dkan_tables a spreadsheet like output of the data with Datatables (Default) or Revolist (optional, now deprecated, will not receive new features currently) is possible
(changed via setting table_plugin in dkan_tables.settings.yml)
If you do not see the tab (like when using DKAN react frontend) you can directly access the visualization page via node/ID/tables. You may also need to set permissions: admin/people/permissions/module/dkan_tables
