Overview
The JavaScript step line chart is like a line chart except that the data points are connected using vertical and horizontal lines, showing a step-like progress. Supports features like zooming, panning, animation, and dynamic updates.
Multi series
Allows you to plot multiple series in a single chart to compare different data sets. Enabling legend and tooltip gives more information about the individual series.
Marker
Marks data points with built-in shapes such as circles, rectangles, ellipses, vertical lines, horizontal lines, diamonds, triangles, pentagons, crosses, and pluses. In addition to these shapes, use images to make the point more attractive.
Data label
Data labels display information about data points. Add a template to display data labels with HTML elements such as images, DIV, and spans for more informative data labels. You can rotate a data label by its given angle.
Multiple axes
Use multiple axes to plot different data sets that widely vary from one other.
Zoom and pan
Enable zooming and panning support when dealing with large amount of data to visualize the data point in any region.
Dynamic stepline chart
Create and update the stepline chart with live data that changes over seconds or minutes.
Empty/null data point
Handle the missed data elegantly with empty points support.
Vertical chart
The stepline chart can be transposed vertically to view the data in a different perspective.
Customization
Customize the color, thickness, and dash array of the stepline chart using built-in APIs.
