When opening note.html / dashboard.html in a web browser from HTML exported notes or dashboards, chart content may sometimes not display.
Cause
Windows Explorer has a feature that allows viewing files inside ZIP archives without extracting them. When trying to view HTML files in a browser using this feature, this problem occurs because the HTML files cannot resolve other dependent files (such as images).
Solution
Please “Extract All” the HTML exported ZIP file.
After extraction, open note.html / dashboard.html.
At that time, there should be a folder called “libs” in the same directory as the note.html file. If this libs folder is not in the same directory, charts within the note will not display.
Therefore, if you move only note.html to another folder, the problem of charts not displaying within the note will occur.
