抑制ggplot中的0值

Question

我用ggplot创建了以下条形图：

library(tidyverse)
temp<-tribble(
 ~kt, ~yes, ~'no', ~'NA',
 "Berne", 47,33, 0,
 "Basel", 60,45,0,
 "Geneva", 64,61,0,
 "Zurich", 19,107,3
)

temp2 <- gather(temp, ' ', val, -kt)
ggplot(temp2, aes(fct_rev(kt), val, fill = ` `)) + 
  geom_col(position = 'fill', color='black') +
  geom_text(aes(label = val), position = position_fill(vjust = 0.5), size=3) +
  scale_y_continuous(labels = scales::percent_format())+theme_bw()+
  labs(x='Canton', y='Percentage')+coord_flip()+     scale_fill_grey(start = 0.9, end = .5)+
  guides(fill=guide_legend(title="Label", reverse=T))

但是，右侧的那些0值看起来非常令人不安。有没有办法在ggplot中抑制它们？

您可以使用以下方法过滤它们：

>ProgressBarActivity.java public class ProgressBarActivity extends AppCompatActivity { private TextView txtProgress; private ProgressBar progressBar; private int pStatus = 0; private Handler handler = new Handler(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_progress); txtProgress = (TextView) findViewById(R.id.txtProgress); progressBar = (ProgressBar) findViewById(R.id.progressBar); new Thread(new Runnable() { @Override public void run() { while (pStatus <= 100) { handler.post(new Runnable() { @Override public void run() { progressBar.setProgress(pStatus); txtProgress.setText(pStatus + " %"); } }); try { Thread.sleep(100); } catch (InterruptedException e) { e.printStackTrace(); } pStatus++; } } }).start(); } } > activity_progress.xml <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.placio.android.custom_progressbar_circular.MainActivity" > <RelativeLayout android:layout_width="wrap_content" android:layout_centerInParent="true" android:layout_height="wrap_content"> <ProgressBar android:id="@+id/progressBar" style="?android:attr/progressBarStyleHorizontal" android:layout_width="250dp" android:layout_height="250dp" android:layout_centerInParent="true" android:indeterminate="false" android:max="100" android:progress="0" android:progressDrawable="@drawable/progress_drawable" android:secondaryProgress="0" /> <TextView android:id="@+id/txtProgress" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBottom="@+id/progressBar" android:layout_centerInParent="true" android:textAppearance="?android:attr/textAppearanceSmall" /> </RelativeLayout> </RelativeLayout> > progress_drawable.xml <?xml version="1.0" encoding="utf-8"?> <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:fromDegrees="-90" android:pivotX="50%" android:pivotY="50%" android:toDegrees="270" >
