用动态字体缩放增强可视化效果

11月 16, 2023
everviz 2023 年 10 月版本可确保您的可视化在所有出版目的地保持最佳可读性。

everviz is a cloud-based data visualization platform that empowers users to create visually appealing interactive charts, maps, and other visuals.

The October 2023 update of everviz adds a new dynamic font scaling feature. This allows chart text to be intelligently resized to fit your publishing destination, whether it's intended for print, video, or the web. It is particularly useful when exporting visualizations in video format, where the text size requirements are significantly different from those of an online article. Dynamic font scaling helps maintain a consistent visual quality across your visualizations.

Adding the SMI to your stock charts can help users gain a competitive edge in the market.
