In this blog, we’ll explore how to create a WPF Heat Map using Syncfusion Heatmap Chart control. We will also demonstrate how to customize tooltips to enhance user interaction, providing detailed insights when hovering over specific data points. Our dataset will focus on global land and ocean average temperature anomalies from 2004 to 2024, helping us observe climate trends over time.
A Heat Map Chart is a graphical representation where data points are color-coded based on their values. This visualization is particularly useful for:
- Analyzing long-term climate trends, financial fluctuations, and healthcare data.
- Quickly identifying patterns, outliers, and regional variations.
- Representing relationships between variables in a structured grid format.
The TemperatureData is bind to the heat map using the ItemsSource property. The mapping of each month's temperature is defined in the TableMapping resource, linking the Year and each month's data (e.g., January, February, etc.). The ItemsMapping are used to bind the model to Heat Map.
we'll focus on customizing the appearance of the heat map based on the cell values to enhance the visualization.
To improve the visual representation of data, we can map specific temperature values to a range of colors. Syncfusion’s WPF Heat Map offers a ColorMappingCollection that allows you to assign different colors to specific data values. We define a collection of color mappings where each value corresponds to a particular color. The values will then be reflected in the heat map cells, making it easier to understand temperature anomalies.
If you are facing a Path too long exception when building this project, follow these steps:
- Close Visual Studio.
- Rename the repository to a shorter name.
- Reopen the project and build again.
