Read on to find out the important aspects of FusionCharts responsive and interactive live data streaming charts. Learn more about features like its real-time message logger, alert manager, interactive legends, and context menus.
Real-time line charts show how a dependent variable changes with the values of the independent variable. A prime example of this is the fluctuations of a stock price chart over a month or a year.
Similar to line charts, real-time area charts also show changes in the dependent variable over time.
In addition to line and area charts, real-time column charts are a means of comparing several variables and data values as they vary over time.
Stacked area charts show multiple area charts, stacked on top of each other and corresponding to multiple datasets. The real-time version of this chart updates itself over time.
You can use Real-time stacked column charts to compare different data values belonging to different categories. They present the breakdown of each item placed on top of each other. These charts also autonomously update to show real-time variations in your data.
Finally, real-time dual-line charts have two y-axes to compare how a pair of variables vary together as time passes.
With FusionCharts live charts you can write your own message logger as well as an alert manager. With the message logger, you can show real-time messages within a specialized chart window. The alert manager helps you define actions based on the data points reaching critical values in pre-defined ranges.
With an interactive legend in real-time charts, your users can choose to show a particular data series while hiding the rest. They can also highlight one series in the context of the rest.
With live charts created using FusionCharts, a context menu is displayed at the bottom left corner of the graph. Along with other options, you can switch automatic updates on or off using this menu.
