under Draw()

change 50 to 60
for (uint8_t i = 1; i < 4; i++) if (i * 60 < frame.w) DWIN_Draw_VLine(Line_Color, i * 60 + frame.x, frame.y, frame.h);

under Update()

change 50 to 60
if ((grphpoints % 60) == 0)

i just wanted to add the purpose from changing the value 50 to 60 under Draw() in file --> plot.cpp
is because that makes each vertical line 30 seconds, rather than 25, and so when scrolling, it is more evenly spaced without unnecessary gaps.
