Plugin render limits
<perspective-viewer>
plugins (especially charts) may in some cases generate
extremely large output which may lock up the browser. In order to prevent
accidents (which generally require a browser refresh to fix), each plugin has a
max_cells
and max_columns
heuristic which requires the user to opt-in to
fully rendering View
s which exceed these limits. To override this behavior,
set these values for each plugin type individually, before the plugin itself
is rendered (e.g. calling HTMLPerspectiveViewerElement::restore
with the
respective plugin
name).
If you have a <perspective-viewer>
instance, you can configure plugins via
HTMLPerspectiveViewerElement::getPlugin
and
HTMLPerspectiveViewerElement::getAllPlugins
:
const viewer = document.querySelector("perspective-viewer");
const plugin = viewer.getPlugin("Treemap");
plugin.max_cells = 1_000_000;
plugin.max_columns = 1000;
... Or alternatively, you can look up the Custom Element classes and set the static variants if you know the element name (you can e.g. look this up in your browser's DOM inspector):
const plugin = customElements.get("perspective-viewer-d3fc-treemap");
plugin.max_cells = 1_000_000;
plugin.max_columns = 1000;
