Highlight the selected biomaker in 2D plot. Metabolic sample is visualized as a two dimensional image. Each grid denotes a group of metabolites with similar profiles. Red color means the highly expressed metabolite group and blue color means the lowly expressed metabolite group. In particular, metabolite with chemical shift value 3.55 is highlighted in white color and indicated by the star.
