Hi we are struggling to make this work with the charts. I see the approach and have successfully used this idea to change general text and h1, h2 element font size but the chart x and y axis labels are not effected
Hi @Jen
Sorry to hear the labels are not affected when trying this approach. With troubleshooting CSS and JS being outside of the scope of our support team, our internal team will be unable to assist with this.
However, I suggest considering our Expert Network and reaching out to one of our vetted affiliates for further help accomplishing your customization to your charts. You can find our Expert Network here: Expert Network
