    add the axis and grid lines of external layers, respectively. (2020-08-24, Mon)
+ 0.99.12
  + add upper and lower grid lines of y. (2020-08-26, Wed)
+ 0.99.13

  + update `normxy` to fix the bug when negative values are present. (2020-09-04, Fri)
  + update `ggplot_add` method of `geom_fruit` to support the orientation

+ 0.99.16
  + change `add.axis` in axis.params from TRUE or FALSE to `x` or `y` or `xy`. (2020-09-05, Sat)
  + remove `add.grid` in `grid.params` and default of `grid.params` is NULL. (2020-09-07, Mon)
  + update method of `axis tick` and remove `nbreaks`, the breaks will be calculate by `pretty`. (2020-09-07, Mon)
  + use `substitute` to allow list of `axis.params` or `grid.params` has empty argument, 
    eg `grid.params=list(color="black",)`. (2020-09-07, Mon)
+ 0.99.17
  + change `add.axis` to `axis` in `axis.params`. (2020-09-08, Tue)
+ 0.99.18
  + add `nbreak` in `axis.params` of `geom_fruit`, it will be sent to `n` of `pretty` to 
    generate the desired number of intervals of `axis`. (2020-09-08, Tue)
+ 0.99.19
  + modified the namespace, remove `geom_vline`, add `geom_segment`. (2020-09-11, Fri)
  
# 0.0.1

+ add vignettes. (20200707, Tue)

# 0.0.0.9

+ support add the axis text of extra layer of `geom_fruit` using `geom_axis_text`. (20200630, Tue)
+ optimize normalization of extra layer data. (20200701, Wed) 
+ fixed bug: changed layer to layers. (20200703, Fri)

# 0.0.0.8

+ support data of NULL in `geom_fruit`, and user can add data by `%<+%` of `ggtree`. (20200628, Sun)

# 0.0.0.7 

+ add `geom_fruit_list` to support add the same position for multi layers. (20200622, Mon)

# 0.0.0.6

+ automatically detect the 'position'. (20200612)

# 0.0.0.5

+ change `pratio` parameter to `pwidth` and remove `tippoint` parameter.
+ change `geom_add` function to `geom_totree` function. (20200610)

# 0.0.0.4

+ support tip point for `geom_star` or `geom_point`
+ support `geom_boxplot` and `geom_violin` (20200606)

# 0.0.0.3

+ add marginal line, and when x is character, the new x normalized 
  should be started with zero. (20200601)

# 0.0.0.2

+ The distance between the panel and tree can be adjusted 
  using the "offset". The value of associate panel were 
  normalized in the range of x of tree. The width can be 
  adjusted using the "pratio". The "offset" and "pratio" 
  are the ratio related to tree. (20200529)

# 0.0.0.1

+ first version to `github` (20200528)
