Data visualization is a common method to visually illustrate relationships in the data. The purpose of data visualization is to present data that are too numerous or complicated to be described adequately in the text and in less space.
As a human, we would be pleased to view that graphical data in a qualitative visual form. This can be done with QML which provides fluid animations and visually appealing components.
The Chart.js is the heart of the application. It contains the default properties of each graph, initialization code, code for drawing the graph/chart and the mathematical functions for frequently used calculations.
The application depicts the following graphs:
- Bar graph
- Line graph
- Pie graph
- Doughnut graph
- Polar graph
- Radar graph
Full source code for the binding js with QML with graph sample application is available on our developer site.
