Nginx Proxy not working as expected

I make calls to the backend server were apache is running using Javascript. I have setup an nginx proxy and route all graphite and elasticsearch requests through it to the server were apache2 is running.

Nginx does make the proxy call to the server However, it adds the location to the end of the URL.

for example: http://10.xxx.xxx.23/graphite when passed to nginx will call http://23.xxx.xxx.1:80/graphite. I don't want the /graphite in the end I want ngix to simple call http://23.xxx.xxx.1:80 ?

I have pasted my nginx.conf file below

config.js

datasources: {
graphite: {
type: 'graphite',
url: "http://" + window.location.host + "/graphite",
},
elasticsearch: {
type: 'elasticsearch',
url: "http://" + window.location.host + "/elasticsearch",
index: 'grafana-dash',
grafanaDB: true,
}
}
