Hi Suho and Ramindu, Above fix is no needed as "else" block will be executed for realtime providers (push mode) [1]. There we call "draw" method of the chart which draw the chart even without the data. Then only we register call back to push. In that call back we don't redraw the chart we just update previously drawn chart. If call draw() on callbacks there will be a chart refreshing in the UI as it redraws.
Here he new provider is going to access DAS tables using query params which is a pull mode operation [2]. There basically we draw the chart with pulled data and then set interval to call draw method periodically. If its a such operation in that particular provider getMode should be "PULL" as in the batch provider [3] Also please refer the branch 2.0.x of carbon-dashboard which is used cep and das packs instead of master branch.
