I am new at C3.js, and I am trying to do a timeseries chart.
My goal is to set Portuguese Brazil as the default locale. I already saw that d3.js has an implementation that change the time format. But I am having problem to implement this at my c3.js file.
Right now, the axis X is showing the months in English as default.
!(https://im.ge/i/F2osMX[print of screen with months in English at axis X ]1)
I would like it to show the months in Portuguese ["Jan", "Fev", "Mar", "Abr", "Mai", "Jun", "Jul", "Ago", "Set", "Out", "Nov", "Dez"].
Thank you
UPDATE: Here is the code I have now.

You can implement this using the d3-time-format module and setting a default locale. Here's the section of your code with the relevant changes:
