Question

我使用命令subplot(1,2,1)和subplot(1,2,2)对图表进行了子图绘制。我绘制了数据。如你所见，我在图中有2张图。

我想改变两个图的y轴边界。

例如，我第一张图有ylim=[0 0.5]，第二张图有ylim=[0 1.5]。我想改变这些ylim的。

首先，您需要访问您的数字：

public void encodeImagetoString() {
        new AsyncTask<Void, Void, String>() {

            protected void onPreExecute() {

            };

            @Override
            protected String doInBackground(Void... params) {
                BitmapFactory.Options options = null;
                options = new BitmapFactory.Options();
                options.inSampleSize = 3;
                bitmap = BitmapFactory.decodeFile(imgPath, options);

                ByteArrayOutputStream stream = new ByteArrayOutputStream();

                bitmap.compress(Bitmap.CompressFormat.PNG, 50, stream);
                byte[] byte_arr = stream.toByteArray();

                encodedString = Base64.encodeToString(byte_arr, 0);
                return "";
            }

            @Override
            protected void onPostExecute(String msg) {
                Log.e("Success" , "Success");
            }

        }.execute(null, null, null);
    }

现在您的子图存储在＆＃39; Children＆＃39;你的身材的领域。在这种情况下，它将是一个包含两个轴对象的单元数组，代表您的子图。

Myfig=gcf; %If the figure you want to modify is the current figure
Myfig=figure(1); %Replace 1 by the number of your figure, this command will make figure(1) your current figure and return its handle in Myfig.

更新：如果您已经知道先验要更改哪个子图，以及 AND 您要修改的数字是当前的图：

%If you don't have legends
Allsubplots=get(Myfig,'children'); 

% If you have legends, they will also appear as children of your fig
% Meaning you have to seek all fig's children that are of type 'axes'
Allsubplots=findobj(Myfig,'type','axes');

MySubplot1=Allsubplots(1);
MySubplot2=Allsubplots(2);

%%Change ylims of first subplot to [Ymin1 Ymax1] :
set(MySubplot1,'ylim',[Ymin1 Ymax1]);

%%Same for second subplot :
set(MySubplot2,'ylim',[Ymin2 Ymax2]);

改变子图的ylim
