EspressChart is a powerful yet user-friendly toolkit designed for Java and Web developers to integrate dynamic and business intelligence charting capabilities into web pages, applications, servlets, and JSPs. Built entirely in Java, it ensures cross-platform compatibility and can be deployed across various environments, including headless Unix systems and popular application servers such as Tomcat, JBOSS, WebSphere, and Oracle Application Server. It supports both client-side chart manipulation through Chart Viewer and server-side generation with output in formats like GIF, BMP, JPEG, PNG, SVG, and PDF. EspressChart features a comprehensive API and a visual design interface—the Chart Designer—which enables users to create charts via a point-and-click method and save them as templates for streamlined deployment.
EspressChart Key Features:
- Over 30 available chart types:
- EspressChart supports over 30 different two-dimensional and three-dimensional charts.
- Full range of data access:
- EspressChart can directly connect to relational databases to draw data. It can also draw data from text files, from Excel files, from WSDL SOAP and SalesForce SOAP Services, or pass data directly through the API. Users can also design parameterized charts that allow run-time data filtering. With automatic database connections, it's easy to build Web pages that dynamically generate charts with up-to-the-second information.
- Highly Customizable:
- Nearly every chart element can be modified or customized in some fashion. In fact there are over 240 different customizable chart attributes. EspressChart supports internationalization with local-specific, and time zone formatting. Advanced features include time-series zooming, data drill-down, parameterized charts, and run-time text substitution.
- Advanced Statistical Analysis:
- In addition to the large array of customization features, EspressChart offers many advanced statistical analysis features. Users can add many different types of trend lines to charts including linear regression, polynomial of any degree, power, exponential, logarithmic, B-Spline curve, as well as normal distribution curves. Other features allow users to create histogram plots, Pareto charts, Heatmap charts (with correlation option) and box charts. For SPC-type applications, users can add control lines and areas.
- True 3D charts:
- 3D charts are rendered in 3D with fast hidden surface removal algorithm that supports real-time pan/zoom, scaling, rotation, light sources and smooth-edged pie and donut charts.
