J-TEXT WebScope: An efficient data access and visualization system for long pulse fusion experiment

A WebScope with data provider both for MDSplus and JTEXTDB is implemented and deployed. The WebScope has been integrated into J-TEXT LogBook, an experimental recording system for J-TEXT. It is now serving J-TEXT daily experiment. In the future more databases as the data source will be supported and it will support visualization of more data types besides waveform.
