Synthetic time series¶
In [3]:
x <- seq(0, 10, 0.25)
serie <- data.frame(x, sin=sin(x), cosine=cos(x)+5)

|---|---|---|---|
| <dbl> | <dbl> | <dbl> | |

Series plot¶
A series plot is a type of chart that displays information as a series of data points connected by straight line segments.
It is similar to a scatter plot except that their x-axis value orders the measurement points.
