利用Matlab繪制一款專屬進度條

更新時間：2022年02月25日 10:45:24 作者：slandarer

MATLAB自帶的進度條是很簡單的，這樣的進度條顯得冷冰冰的。因此，本文將用Matlab來DIY一款專屬的進度條，感興趣的小伙伴可以了解一下

1.使用效果

2.制作歷程

首先我有個程序需要用到進度條，我首先試了一下MATLAB自帶的進度條：

bar=waitbar(0,'讀取數(shù)據(jù)中...');    % waitbar顯示進度條

for i=1:1000
    A(i)=rand();
    str=['計算中...',num2str(100*i/1000),'%'];   % 顯示的文本
    waitbar(i/1000,bar,str)                       
end

但是這樣的進度條顯得冷冰冰的，我就想研究一下其屬性來想辦法看能否對其修飾。

以前的版本系統(tǒng)自帶的進度條可以通過。

set(findobj('type','patch'),'facecolor','b')

這樣的方式改變顏色，但是慢慢的隨著版本更新，這樣的修改方式已經(jīng)不行了，于是我便嘗試查看新版本 waitbar 是怎樣刷新進度條的，我進行了一波 open waitbar 發(fā)現(xiàn)這個函數(shù)就只是創(chuàng)建了figure和axes并不斷更新圖像：

其中更新圖像主要依賴一個名為 uiwaitbar 的函數(shù)：

于是我想當然的試了一下 open uiwaitbar 結果發(fā)現(xiàn)打不開。。。

于是我根據(jù) waitbar.m 的位置順藤摸瓜的在：toolbox\matlab\uitools\private

路徑找到了 uiwaitbar.p 文件，啊加密文件，那沒事了嗷：

雖然是加密文件，但我們還是通過換著參數(shù)調(diào)用發(fā)現(xiàn)這個函數(shù)可能需要用到一些png或者css文件：

不過本人css用的確實不夠熟，同時也比較難看出加密文件到底是怎么調(diào)用css文件的，但是總結來說waitbar就只是一個不斷刷新圖像的figure而已，我們自己寫的話甚至可以不用css或者png，直接用自帶的畫圖函數(shù)都可以。

3.函數(shù)用法

寫了以下幾個進度條函數(shù)（四種風格）：

waitBar_SL1.m(僅支持英文)
waitBar_SL2.m
waitBar_SL3.m
waitBar_SL4.m

基本用法like this:

bar=waitBar_SL2(0,'loading ...');  % 初始化

for i=1:1000
    A(i)=rand();
    str=['precess - ',num2str(round(i/10)),'%']; % 顯示的文本
    waitBar_SL2(bar,i/1000,str);
end

4.工具函數(shù)完整代碼
