Line charts are represented by a series of data points connected by a line (similar to Area Charts but the space between the data lines and the X axis is not filled in). Line charts are most often used to visualize data that changes over time.
Line
The line chart connects the data points with a straight line, drawing as many lines as the number of series in the chart.
Stacked line
A stacked line chart works similarly to a line chart, but stacking the data series on top of each other in order instead of overlapping them.
100% stacked line
A 100% stacked line chart stacks the data series on top of each other and shows the relative percentage of the values instead of the actual values, similarly to a 100% stacked Column Chart.
Smooth line
The smooth line chart connects the data points with a spline (curved line) instead of with a straight line.
Timeline
A timeline chart is a way of displaying the variation of a series of values over time. Technically, a timeline chart is similar to a line chart, with the X axis representing the time as a continuum.
Step Timeline
A step timeline chart is similar to a line chart, with the X axis representing the time as a continuum. This chart type uses vertical and horizontal lines to connect the data points in a series forming a step-like progression.
Smooth Timeline
A step timeline chart is similar to a line chart, with the X axis representing the time as a continuum. The smooth timeline chart connects the data points with a spline (curved line) instead of with a straight line.
Sparkline
A sparkline is a very small line chart, typically drawn without axes or coordinates. It presents the general shape of the variation over time of some measurement, such as temperature or stock market price, in a simple and highly condensed way. Whereas the typical chart is designed to show as many data as possible and is set off from the flow of text, sparklines are intended to be succinct, memorable so that they can be embedded in the text.
Step line
The step line chart type is similar to regular line chart, but it does not use the shortest distance to connect two data points. Instead, this chart type uses vertical and horizontal lines to connect the data points in a series forming a step-like progression.
