Custom Web Control
About Scatter Chart
Scatter Chart is a high-performance Custom Web Control (CWC) specifically engineered for industrial SCADA environments. It enables engineers and operators to visualize complex correlations between two distinct process variables in real-time. By integrating seamlessly into WinCC Unified and WinCC V8, it provides a sophisticated data analysis tool directly within the HMI screen.
Key Features
- Dynamic Correlation Analysis: Instantly visualize the relationship between X and Y process parameters.
- Interactive Data Points: Includes built-in support for tooltips and the PointClicked event, allowing operators to trigger specific HMI actions or navigation when selecting data.
- High-Performance Rendering: Utilize the refreshChart method to ensure the visualization remains sharp and responsive during container resizing or data updates.
- Process-Driven Visuals: Bind the points array directly to HMI tags for continuous data stream representation.
Customization
The Scatter Chart offers 8 distinct properties for deep integration into your corporate design. You can modify the backgroundColor and toggle the showGrid visibility to match your dashboard's aesthetic. Axis clarity is maintained through configurable xAxisLabel and yAxisLabel fields, while the chartTitle provides immediate context. For data representation, the pointColor and pointSize can be adjusted to highlight specific data densities or process states.
Use Cases
This control is ideal for identifying anomalies in production, analyzing the relationship between temperature and pressure in chemical reactors, or monitoring motor efficiency across varying load conditions. It is a vital tool for quality control and predictive maintenance dashboards.
Compatibility
Works with WinCC Unified (TIA Portal) and WinCC V8. Includes full documentation with installation instructions for both platforms.
💡 TIA Portal Reminder: Remember to uncheck the "Read only" option in TIA Portal when linking a tag to a property that needs to be written from the Custom Web Control. If you do not, the CWC will only be able to read the HMI tags and not write to them.
