Analysis on the correlation between species and D-xylose, GAS and VIP. The data information of the two-dimensional matrix can be reflected by the color change. The color depth represents the size of the value, and the color gradient can reflect the change trend. The regions in the graph tend to be blue, which represents negative correlation, and red represents positive correlation. The darker the color means the greater the absolute value of correlation coefficient (*P < 0.05, **P < 0.01)
