# [Linechart] - General purpose node for Line Charts
|
|
# A line chart or line plot or line graph or curve chart is a type of chart which
|
|
# displays information as a series of data points called 'markers'
|
|
# connected by straight line segments.
|
|
# It is a basic type of chart common in many fields. It is similar to a scatter plot
|
|
# except that the measurement points are ordered (typically by their x-axis value)
|
|
# and joined with straight line segments.
|
|
# A line chart is often used to visualize a trend in data over intervals of time -
|
|
# a time series - thus the line is often drawn chronologically.
|
|
# In these cases they are known as run charts.
