Charts not displaying at all?
Opened this issue · 0 comments

Combining some of the code from the full example in the example folder (mainly just the candles list), and a simplified version from the README.md, the resulting .html file has no chart to display. The theme is applied (as shown from the background colour), but no chart. Ideas? Windows 10, go 1.19.
package main
