更新時(shí)間：2023年11月05日 09:53:23 作者：微小冷
這篇文章主要為大家詳細(xì)介紹了python如何通過(guò)設(shè)置WordCloud參數(shù)實(shí)現(xiàn)定制詞云,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下
添加整型參數(shù)
我們所有的設(shè)置都放在了wcDct中，所以若想用更多的參數(shù)來(lái)定制詞云，那么只需在wcDct中添加內(nèi)容，例如下面這些整型參數(shù)
其次，WordCloud中有很多參數(shù)的數(shù)據(jù)類(lèi)型都是整型，這些適用于Spinbox
| 參數(shù) | 說(shuō)明 | 合適的范圍 | 步長(zhǎng) |
|---|---|---|---|
| width | 詞云寬度 | 100-2000 | 10 |
| height | 詞云高度 | 100-2000 | 10 |
| min_font_size | 最小文字尺寸 | 1-50 | 1 |
| max_font_size | 最大文字尺寸 | 10-1000 | 10 |
| font_step | 字體步長(zhǎng) | 1-20 | 1 |
| max_words | 最大單詞數(shù) | 10-500 | 10 |
| min_word_length | 最短單詞長(zhǎng)度 | 0-10 | 1 |
| scale | 圖像縮放 | 默認(rèn)是1 |
下面就是要向wcDct中添加的內(nèi)容。
wcDct = {
"最小文字" : {
"ctrl": ttk.Spinbox,
"paras" : {"width":10, "from_":1, "to":50, "increment":1},
"default":4,
"call" : "min_font_size"},
"最大文字" : {
"ctrl": ttk.Spinbox,
"paras" : {"width":10, "from_":10, "to":1e3, "increment":10},
"default":400,
"call" : "max_font_size"},
"字體步長(zhǎng)" : {
"ctrl": ttk.Spinbox,
"paras" : {"width":10, "from_":1, "to":20, "increment":1},
"default":10,
"call" : "font_step"},
"最短詞長(zhǎng)" : {
"ctrl": ttk.Spinbox,
"paras" : {"width":10, "from_":0, "to":10, "increment":1},
"default":1,
"call" : "min_word_length"},
"最多詞數(shù)" : {
"ctrl": ttk.Spinbox,
"paras" : {"width":10, "from_":10, "to":500, "increment":10},
"default":200,
"call" : "max_words"},
"圖像縮放" : {
"ctrl": ttk.Spinbox,
"paras" : {"width":10, "from_":0.5, "to":5, "increment":0.1},
"default":1,
"call" : "scale"},
}
布爾型參數(shù)
然后是一些布爾類(lèi)型的參數(shù)，適合用Checkbutton
| 參數(shù) | 說(shuō)明 | 類(lèi)型 | 適用組件 |
|---|---|---|---|
| repeat | 是否重復(fù)單詞 | 默認(rèn)False | Checkbutton |
| include_numbers | 是否包含數(shù)字 | 默認(rèn)False | |
| normalize_plurals | 是否去掉詞尾的s | 默認(rèn)True |
wcDct = {
"單詞重復(fù)" : {
"ctrl": ttk.Checkbutton,
"paras" : {"width":10},
"default": False,
"call" : "repeat"},
"包含數(shù)字" : {
"ctrl": ttk.Checkbutton,
"paras" : {"width":10},
"default": False,
"call" : "include_numbers"},
"去詞尾s" : {
"ctrl": ttk.Checkbutton,
"paras" : {"width":10},
"default": False,
"call" : "normalize_plurals"},
}
背景顏色
最后，還有一個(gè)背景顏色對(duì)話框
| 參數(shù) | 說(shuō)明 | 對(duì)話框類(lèi)型 | 說(shuō)明 |
|---|---|---|---|
| background_color | 背景色 | 顏色對(duì)話框 | 默認(rèn)"black" |
wcDct = {
"背景顏色" : {
"ctrl": DialogButton,
"paras" : {"height":5, "widthL":22, "widthR":8, "logtype":"顏色"},
"call" : "background_color",
"default" : "balck"},
}
更改之后的界面如下
詞云生成邏輯
有了這些之后，還要修改詞云生成邏輯，即調(diào)用這些參數(shù)所獲得的值，最后根據(jù)上圖中的參數(shù)，得到點(diǎn)云如下
