Show your basic elements of the ggheatmap

ggheatmap_plotlist(p)

Use ggheatmap_theme to make your figure more elegant

p%>%
  ggheatmap_theme(1:5,
                  theme =list(
                    theme(axis.text.x = element_text(angle = 90,face = "bold",size = 10),
                          axis.text.y = element_text(colour = "red",face = "bold")),
                    theme(legend.title = element_text(face = "bold")),
                    theme(legend.title = element_text(face = "bold")),
                    theme(legend.title = element_text(face = "bold")),
                    theme(legend.title = element_text(face = "bold"))
                    ))

Set your border color

ggheatmap(df,cluster_rows = T,cluster_cols = T,scale = "row",
              text_show_rows = text_rows,
              border = "grey",
              cluster_num = c(3,3),
              tree_color_rows = c("#008B45FF","#631879FF","#008280FF"),
              tree_color_cols = c("#1F77B4FF","#FF7F0EFF","#2CA02CFF"),
              annotation_rows = row_metaData,
              annotation_cols = col_metaData,
              annotation_color = col
)%>%
  ggheatmap_theme(1,theme =list(theme(axis.text.x = element_text(angle = 90,face = "bold",size = 10),
                          axis.text.y = element_text(colour = "red",face = "bold"))))

Chage your heatmap cell shape

ggheatmap(df,cluster_rows = T,cluster_cols = T,scale = "row",
          text_show_rows = text_rows,
          border = "grey",
          shape = "circle",

          tree_color_rows = c("#008B45FF","#631879FF","#008280FF"),
          tree_color_cols = c("#1F77B4FF","#FF7F0EFF","#2CA02CFF"),
          annotation_rows = row_metaData,
          annotation_cols = col_metaData,
          annotation_color = col
)%>%
  ggheatmap_theme(1,theme =list(theme(axis.text.x = element_text(angle = 90,face = "bold",size = 10),
                                      axis.text.y = element_text(colour = "red",face = "bold"))))

          text_show_rows = text_rows,
          border = "grey",
