Raspbian GNU/Linux 9 using Chromium

Describe the bug

When following the Live-Updates tutorial from https://dash.plot.ly/live-updates, the graphs appear in the web browser, but the graphs are empty. Below are screen shots of what happened vs. what is expected respectively.

SOLUTION:

The solution was to simply increase the interval to 1 * 10000 ms. Then the live-updates worked as expected. Not entirely sure why, but wanted to bring this issue up. Thanks!

Comienza reproduciendo el tutorial de Live-Updates en Raspbian GNU/Linux 9 con Chromium, utilizando las versiones de los paquetes indicadas y comparando el intervalo predeterminado con 10000 ms. Se considera completado cuando los gráficos se rellenan de forma fiable en el intervalo documentado, o cuando se documentan la causa específica de Raspberry Pi y la solución alternativa necesaria.
