Basic Examples (7) 

Annotate a graphical object with an underbrace:

In[1]:=

Out[1]=

Use multiple annotations:

In[2]:=

Out[3]=

By swapping the order of the two anchor points, create an overbrace:

In[4]:=

Out[5]=

Adjust the position and rotation of the label:

In[6]:=

Out[7]=

By default, the brace automatically adjusts its rotation to the annotated object:

In[8]:=

Out[9]=

Style the labels as well as the curves:

In[10]:=

Out[11]=

Use Point objects directly as anchor points:

In[12]:=

Out[14]=

Scope (10) 

Label content (2) 

Use the underbrace with no label:

In[15]:=

Out[15]=

---

The label does not have to be text:

In[16]:=

Out[16]=

Label position (3) 

Position the label further from the cusp:

In[17]:=

Out[18]=

The offset is taken in the direction of the cusp:

In[19]:=

Out[19]=

---

The textual label can be offset in the horizontal and vertical directions using an additional argument:

In[20]:=

Out[20]=

Any specification that is valid for the third argument of Text is also allowed. Here, an Offset is used:

In[21]:=

Out[21]=

---

Specify the relative position of the label with respect to the edges:

In[22]:=

Out[22]=

Curve dimensions (2) 

Make the edges longer:

In[23]:=

Out[23]=

---

Specify the relative position of the cusp with respect to the edges:

In[24]:=

Out[24]=

Presentation (3) 

Choose different colors, thicknesses, etc. for the curve:

In[25]:=

Out[25]=

---

Choose different styles for the label:

In[26]:=

Out[26]=

---

Style both the curve and the label:

In[27]:=

Out[27]=

Options (8) 

Direction (3) 

By default, the curve stretches between the two anchor points:

In[28]:=

Out[30]=

Specify explicitly the direction of the edges:

In[31]:=

Out[31]=

The direction can also be specified as a vector:

In[32]:=

Out[32]=

RotateLabel (3) 

The label is by default parallel to the brace:

In[33]:=

Out[33]=

Disable rotation:

In[34]:=

Out[34]=

---

The angle can also be given explicitly:

In[35]:=

Out[35]=

---

The combination of both approaches yields an automatically rotated label with the explicitly given rotation offset:

In[36]:=

Out[36]=

RoundingRadius (2) 

Adjust the radius of the joints:

In[37]:=

Out[37]=

---

The radius of the cusp and outer joints can be specified independently:

In[38]:=

Out[38]=

Applications (2) 

Make a technical drawing with proper physical units:

In[39]:=

Out[39]=

Describe the regions where a given function is monotonically increasing and decreasing:

In[40]:=

Out[41]=

In[42]:=

Out[42]=

Properties and Relations (1) 

GraphicsBrace can be used in Graphics the way that an underbrace is used in text:

In[43]:=

Out[43]=

Possible Issues (5) 

When the first argument is to be taken as a literal, wrap it in Inset:

In[44]:=

Out[44]=

When the other arguments are not numeric, no evaluation of GraphicsBrace takes place:

In[45]:=

Out[46]=

In[47]:=

Out[47]=

The label may be set too close to the cusp:

In[48]:=

Out[49]=

Position the label further from the cusp:

In[50]:=

Out[50]=

When the line segments are too small with respect to the rounding radii, undesired behavior occurs:

In[51]:=

Out[51]=

To prevent this, adjust the rounding radii appropriately:

In[52]:=

Out[52]=

For an overbrace, the label is upside down:

In[53]:=

Out[53]=

Turn off the automatic rotation of the label:

In[54]:=

Out[54]=

Neat Examples (2) 

Use the brace as a graphics primitive for artistic drawing:

In[55]:=

Out[55]=

Annotate the side lengths of a dynamically changing triangle:

In[56]:=

Out[60]=
