New Style Preset code in JSON - How do I set up my "Default" in the JSON?

Hi andy808 ,

Thank you for sharing the updated JSON and clarifying the issue and thank you Sahir_Maharaj for the helpful response!

Power BI does not automatically apply a named preset as the default. Instead, it uses the settings under the "*" section as the default style for all visuals of that type.In this case, columnChart.

To apply your Light Mode styling by default,try using below :

"visualStyles": {
"columnChart": {
"*": {
"legend": {
// Example Light Mode 
"show": true,
"position": "Top",
"fontColor": { "solid": { "color": "#000000" } }
},
"stylePresets": [
{ "name": "Light Mode Preset" },
{ "name": "Dark Mode Preset" }
]
},
"Light Mode Preset": {
"legend": {
// Keep your Light Mode settings here for manual use
}
},
"Dark Mode Preset": {
"legend": {
// Dark Mode settings
}
}
}
}
This way, the Light Mode style is applied by default, and users can still switch to the Dark Mode preset manually in the Format pane if required.

Hope this resolve your query.If so,consider accepting it as solution.

Thank you.

Pallavi.
