Case Uses & Industries

Digital Line (Step Line) graphs can be used to monitor changes over both short and long time periods. Line graphs can perform better than bar graphs when there are smaller changes. However, step line charts are more effective for highlighting the magnitude of the changes. This is because they visualize what’s happening between data points. An example use case could be to display inventory levels.

We’re proud to support thousands of developers and innovative organizations across the world. Our charts are commonly used in web applications and data dashboards for the following sectors: oil and gas, science, medicine, engineering, finance, trading, and more.

Could our charts help you display your data in a way that is more practical for your end use case?
