### Chart

**chartsgraphgraphs**

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.

A chart is a graphical representation of data, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart".

### Time series

**time series analysistime-seriestime-series analysis**

A line chart is often used to visualize a trend in data over intervals of time â€“ a time series â€“ thus the line is often drawn chronologically.

Time series are very frequently plotted via line charts.

### Run chart

**run sequence plot**

In these cases they are known as run charts.

It is therefore a form of line chart.

### William Playfair

**PlayfairPlayfair, WilliamPlayfair cycle**

Some of the earliest known line charts are generally credited to Francis Hauksbee, Nicolaus Samuel Cruquius, Johann Heinrich Lambert and William Playfair.

The founder of graphical methods of statistics, Playfair invented several types of diagrams: in 1786 the line, area and bar chart of economic data, and in 1801 the pie chart and circle graph, used to show part-whole relations.

### Scatter plot

**scatterplotscatter plotsscatter diagram**

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.

Scatter charts can be built in the form of bubble, marker, or/and 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.

### Table (information)

For example, if one were to collect data on the speed of a body at certain points in time, one could visualize the data by a data table such as the following:

### Gradient

**gradientsgradient vectorvector gradient**

Further, measurements such as the gradient or the area under the curve can be made visually, leading to more conclusions or results from the data table.

### Curve fitting

Charts often include an overlaid mathematical function depicting the best-fit trend of the scattered data. Such curve fitting functionality is often found in graphing software or spreadsheets.

Such curve fitting functionality is often found in graphing software or spreadsheets.

Best-fit curves may vary from simple linear equations to more complex quadratic, polynomial, exponential, and periodic curves.

The threshold of pain or pain threshold is the point along a curve of increasing perception of a stimulus at which pain begins to be felt.

### Pareto chart

**pareto analysisPareto plots**

A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line.

### Fan chart (time series)

**fan chart**

In time series analysis, a fan chart is a chart that joins a simple line chart for observed past data, by showing ranges for possible values of future data together with a line showing a central estimate or most likely value for the future outcomes.

### Climate spiral

Hawkins credited a "Friday afternoon" email from Norwegian climatologist Jan Fuglestvedt for the idea of converting a conventional coloured line chart into a spiral, and thanked Fuglestvedt's wife, Taran FÃ¦hn, for having suggested it to Fuglestvedt.

The transmission curve or transmission characteristic is the mathematical function or graph that describes the transmission fraction of an optical or electronic filter as a function of frequency or wavelength.
