Why is the closing price in the marketwatch and the chart different?

I was checcking the 30 minutes chart of Spicejet after the market closed but the closing price on the marketwatch and the chart are different. If I check the daily time they match, can somebody explain why? https://tradingqna.com/uploads/default/original/2X/9/94017ca96aa6df5d94af566896984feacdf339a2.png
