You can start a job and then periodically request and store information about the running job and vertices from using corresponding REST calls [1]. The data will be in JSON format. After the job finished, you can stop requesting data.
Next you parse the JSON, extract the information you need and give it to some plotting library. As I said, it is not possible to pass this data back into Flink's dashboard, but you have to process and plot it yourself.
