xlsxwriter + mplfinance: Plot Stock Chart in Excel Worksheet

[KMV]

I was able to insert charts into multiple sheets. However, the chart was first saved on the local drive and then inserted in spreadsheet.

for ticker in ticker:
	workbook.add_worksheet(ticker) 
	activeSheet = workbook.get_worksheet_by_name(ticker)
	filt2 = (dfInit["Ticker"] == ticker)
	mpf.plot(dfInit[filt2], title = ticker, type = "candle", style = "classic", savefig = ticker + ".png")
	activeSheet.insert_image(1, 1, ticker + ".png")

Can we do the same without saving the png to the local drive?
