TREEMAP CHART TRONG EXCEL DE LAM GI SOFTWARE
One of the rare tools in the domain of software visualization that follows this hierarchy-based approach is GAMMATELLA. Additionally, an important advantage of using the hierarchy in the visualization is to clearly represent even extensive software systems. Most of the metrics-based approaches do neither support the hierarchical structure nor the requirements to create metrics-based views on higher abstraction levels. However, the hierarchy of the entities as a fundamental characteristic of software systems is ignored by these and many other existing visualization tools.
The newer tool Visual Insight offers some visualizations for software metrics, although these representations are mostly bar, line, and pie charts, matrix views, and graph representations.
TREEMAP CHART TRONG EXCEL DE LAM GI CODE
A well known early tool for visualizing software metric data is SeeSoft, which arranges lines of code as pixels in a box, whereby their color stands for a certain value of a chosen metric. Other tools like Code- Crawler focus on the metrics aspect, especially to represent multiple metric values for one software entity. In such approaches metrics values are represented by visual attributes like size or color of graph nodes denoting the software entities. 2D and 3D graphs focus on the relational structure of software entities including the hierarchy aspects. In the field of software visualization different approaches exist to address the problem of creating visual representations of hierarchical software systems. Examples of software metrics are the widely used lines of code measure or the number of public attributes in a class. These are used to quantitatively characterize properties of software entities, and to provide numerical abstractions of the entities themselves. In the context of program comprehension and quality analysis of large software systems, a enormous number of software metrics have been defined. They allow the identification of problem areas, the illustration of tendencies, and thereby help to improve the quality of software products as well as to increase the efficiency of the development process. CR Categories: D.2.8 : Metrics I.3.8 : Applications Keywords: Treemaps, Software Metrics, Voronoi Diagrams Software metrics are quantitative measures of the degree to which a software system, a component, or process possesses a given attribute. Additionally, we describe techniques that allow the user to investigate software metric data of complex systems by utilizing transparencies in combination with interactive zooming. The layouts are computed by the iterative relaxation of Voronoi tessellations. Contrary to existing rectangle-based Treemap layout algorithms, we introduce layouts based on arbitrary polygons that are advantageous with respect to the aspect ratio between width and height of the objects and the identification of boundaries between and within the hierarchy levels in the Treemap.
In this paper we present a hierarchy-based visualization approach for software metrics using Treemaps. The concerning methods and tools that support the developers in the stages of analysis, design, implementation, and documentation of the software, are therefore of fundamental importance. Good quality assurance of these often extensive and complex systems, their components, and their development process, has become a decisive competitive advantage. In particular, object-oriented software systems are constructed using an explicit and rich hierarchical structure provided by modelling and programming languages like UML or Java/C++. Typical hierarchy levels of software entities are nested subsystems, packages, modules, functions, classes, methods, and attributes, whereby in large systems one may find up to 20 or more levels.

With this, you can also format the amounts in tooltips of the chart, not only the 'ticks' in the 'yAxes'. For those using Version: 2.5.0, here is an enhancement for solution.
