点棒热图
简介
代谢组组学中常用的图。一般左侧为PLSDA的VIP值,右侧为信号热图。
数据说明
数据为矩阵形式,第一列是代谢物名字,最后一列是VIP值,其他列为信号值(默认zscore转换后绘图)。

写作参考
Integrated visualization of metabolite profiling. Left panel: Variable Importance in the Projection (VIP) scores from partial least‑squares discriminant analysis. The x-axis represents the VIP score, and the y-axis lists metabolites ranked by decreasing importance. Right panel: Heatmap showing relative abundance of significant metabolites (VIP ≥ 1) in control and infected samples. The x-axis indicates sample groups, the y-axis corresponds to the significant metabolites, and the color scale represents normalized signal intensity: red, high accumulation (up‑regulation); blue, low accumulation (down‑regulation); white/intermediate, near‑average levels.
