# How to Specify the Legend Position in Graph Coordinates in Matplotlib

We can specify a legend’s position in a graph by setting the `loc` parameter’s value.

## Examples: Specify Legend Position in Graph Coordinates Matplotlib

``````import matplotlib.pyplot as plt

x=[1,2,3]
y1=[0.5*i+1 for i in x]
y2=[2*i+1 for i in x]

fig,ax=plt.subplots(2,1)

ax.plot(x,y1,'b-',label="0.5x+1")
ax.plot(x,y2,'g-',label="2x+1")
ax.legend(loc="best")

ax.plot(x,y1,'b-',label="0.5x+1")
ax.plot(x,y2,'g-',label="2x+1")
ax.legend(loc="lower left")

plt.tight_layout()
plt.show()
``````

Output: Here, we have a figure with two subplots. The topmost subplot has `loc` set to `best`; this places the legend in the figure’s best position, where we do not have any content.

A similar thing happens in the second subplot at the bottom: the legend is placed at the `lower left` position of the bounding box, covering the entire axes. The bounding box is specified by the `bbox_to_anchor` parameter, whose default value is `(0,0,1,1)`.

The `loc` parameter can take any one of the following values:

`best`
`upper right`
`upper left`
`lower left`
`lower right`
`right`
`center left`
`center right`
`lower center`
`upper center`
`center`

These positions represent the legend’s position, with respect to the bounding box specified by the `bbox_to_anchor` parameter.

Similarly, we can place the legend at any position in the figure by changing the value of the `bbox_to_anchor` parameter. The `bbox_to_anchor` parameter takes a tuple, representing the coordinate, where the corner specified by the `loc` parameter will be placed.

``````import matplotlib.pyplot as plt

x=[1,2,3]
y1=[0.5*i+1 for i in x]
y2=[2*i+1 for i in x]

fig,ax=plt.subplots(2,1)

ax.plot(x,y1,'b-',label="Plot-1")
ax.plot(x,y2,'g-',label="Plot-2")
ax.legend(loc="upper left", bbox_to_anchor=(0.9,0.75))
ax.scatter((0.9),(0.75), s=70, c="red",transform=ax.transAxes)

ax.plot(x,y1,'b-',label="Plot-1")
ax.plot(x,y2,'g-',label="Plot-2")
ax.legend(loc="center right", bbox_to_anchor=(0.6,0.4))
ax.scatter((0.6),(0.4), s=70, c="red",transform=ax.transAxes)

plt.tight_layout()
plt.show()
``````

Output: In the subplot at the top, we have set the `bbox_to_anchor` to `(0.9,0.75)`, which is marked by the red dot on the subplot. The value of the `loc` parameter `"upper left"` represents the `upper left` corner of the legend, which is placed at the red dot.

The subplot at the bottom, the `bbox_to_anchor` is set to `(0.6,0.4)` marked by the red dot on the figure’s bottom axes. The value of `loc` is set to `"center right"`; hence, the bottom axes’ legend has its `center right` corner at the red dot.
