Custom Visual Formatting with JSON File

MallinMatthew — Tue, 26 Aug 2025 08:53:45 GMT

Can anyone tell me if it's possible to format an imported custom visual with an imported JSON file? I know this is possible with the visuals already available but can't quite get it to work for the SPC visual created by the government of western australia.

Thanks

Hi @MallinMatthew ,

Thanks for reaching out to the Microsoft fabric community forum

It is possible to format the SPC custom visual developed by the Government of Western Australia using a JSON theme file but with a few caveats.

What Works:

The SPC visual supports custom formatting via JSON, like native Power BI visuals. You can define properties like lineColor, dotColor, colour_main, and colour_target within the visualStyles section of your JSON file. Here's a snippet that aligns with what others have successfully used:

"visualStyles": {

"*": {

"PBISPC": {

"*": {

"lineColor": [{ "solid": { "color": "#EA1FED" } }],

"dotColor": [{ "solid": { "color": "#EA1FED" } }],

"colour_main": [{ "solid": { "color": "#EA1FED" } }],

"colour_target": [{ "solid": { "color": "#EA1FED" } }]

}

Might Be Tricky

The visual must be correctly identified in your JSON under its internal name (PBISPC).
Not all formatting options may be exposed or supported some properties might be hardcoded or not responsive to theme overrides.
Ensure your JSON file is applied as a theme in Power BI, not just imported as a visual.

Hi Matthew,

I'm the dev for the SPC visual, apologies for these issues! I haven't worked with JSON theming before, so I'm not sure if/how I need to enable it within the visual.

I'll add it to the to-do list to investigate and hopefully resolve asap. You can track in this Github issue: Investigate report theme support · Issue #428 · AUS-DOH-Safety-and-Quality/PowerBI-SPC

Also feel free to open any other issues/requests for the visual, or reach out over email.

Cheers,

Andrew
