Need custom graph

Job ID: 30852159

Budget: $50 – $100 USD

The attached graph has been done using c3js and it is showing, on a % scale, the efficiency of an engine recorded in different moments in time. Sometimes those engines are powered off for maintenance.

My goal is to be able to show a horizontal black line which clearly says that no measurement was taken because of the maintenance time frame.
If you take a look at this url, you'll see the kind of graph I would like to have but without buying highcharts.

The application this will run on is yii 1.1.

You will not have access to anything but will work with the yii developer to get this done.
