上个教程中已经修改了进化树的分支颜色和标签颜色，接下来进行热图绘制
# 数据准备
我们可以从 help 界面查看我们需要输入的数据类型
#heatmap
!title Example of heatmap 图例标题
!showLegends 1 是否显示图例，1：显示，0：不显示
!defaultStrokeColor gold
!defaultStrokeWidth 2
!colorgradient blue, yellow,red 热图配色
!colorgradientMarkLabel 0,5,10,15,20,25 颜色梯度值
# -- heatmap column labels --
!showHeatMapColumnLabel 1 热图表头显示
!heatmapColumnLabels e1,e2,e3,control 表头内容
# -- heatmap --
!heatmap margin=2,colwidth=30,roundedcorner=2 热图内部信息
# -- show data value
!showdataValue show=1,fontsize=12
A -2,3,5,0
B 7,9,10,23
C 13,15,19,8
D 20,22,25,4
根据示例数据将我们的数据修改好
#heatmap
!title Expression of heatmap
!showLegends 0
#!defaultStrokeColor gold

!colorgradient red,white,blue
!showHeatMapColumnLabel 1
# -- heatmap column labels --

!heatmapColumnLabels HS1,HS2,HS3,HS4
# -- heatmap --
!heatmap margin=1,colwidth=30,roundedcorner=5
# -- show data value
!showdataValue show=0,fontsize=12,fontitalic=0,fontbold=1,textangle=-60,fontcolor=red

成品图：
可以看到三个 dataset 已经在右边显示了，可以选择是否显示或者删除，也可以点笔的形状进行修改
# 结果导出
在上方有三个按钮，可以保存为 png 格式、pdf 格式以及 nwk 格式
左侧也有一个按钮，可以保存为多种格式
将 png 格式保存到本地，可以看看效果
fine！！！
