Unable to read default color object

Anonymous — Thu, 20 Jul 2017 08:16:21 GMT

In my capabilities.json I defind an object called color. I'm trying to define it inside my custom visual using :

startingColor: getValue<string>(options.dataViews[0].metadata.objects,'colors','startingColor',"#111111"),

But I'm unable to read the default color, since the visual is not running untill I define a new color in the styling pane.

Hello Anonymous,

Power BI doesn't allow to get default color. However, you might define your own default color to return it to Power BI as a default.

You just need to apply your default color if there's no color in the metadata.

Can you please let me know how to do it? How can I check whether the metadata available or not?

Can you share implementation of getValue function that you use to get color from the metadata?

I figured it out. Thanks. I'm using the condition if (options.dataViews[0].metadata.objects) to check whether the user has made any changes in the format pane or not.
