What are these dashes in place of candles? It is chart of Niftybees. It was showing in 3 min chart so I came to 1 min and still its there.

these are not dashes..these are candles in which open and close are so near and the range is in between open and close.

But so many gaps in between them? Like an electron jumping from one orbit to the other...
