The flexibility and excellence of ggplot2 is unquestionable, so many drawing tools basically need ggplot2 as the operating object. In order to develop a heatmap drawing system based on ggplot2, we developed this tool, mainly to solve the heatmap puzzle problem and the flexible connection between the heatmap and the ggplot2 object. The advantages of this tool are as follows: 1. More flexible label settings; 2. Realize the linkage of heatmap and ggplot2 drawing system, which is helpful for operations such as puzzles; 3. Simple and easy to operate; 4. Optimization of clustering tree visualization.
