Pio compile error with seeed_line_chart.h

I’m getting a compile error for the linechart example that looks a bit strange when using PlatformIO.
Is anyone else seeing this?

Quite possibly related to #143. Adding a build_flags clause and changing the lib_deps to pin to the commit just before ee57707 fixes the problem. (Use -DARDUINO_WATCHY_V10 if you have an older watchy.)

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
build_flags = -DARDUINO_WATCHY_V15
lib_deps =
lib_ldf_mode = deep+
board_build.partitions = min_spiffs.csv

This may help you,
