drawChartextends the line to "now" with a synthetic flat point, styled as a dashed zone to indicate it's not real data.graphUpdate(used for live updates viacmd::update) only appended the new point without ever clearing this synthetic point or its dashed zone, so once a chart had this treatment, any subsequent live update stayed dashed and kept the stale flat segment in front of the new real data.graphUpdatenow removes the synthetic point and resets the zones before adding the new real value, so the chart correctly returns to a solid line as soon as fresh data arrives.
