Excel绘制具有连续x轴的时间序列频率

I want to plot a time series frequency data similar to the below. I tried many types of charts but they all put the time (ie 08:00) exactly under data series column, I also tried to type 8-9 , 9-10, 10-11 ...but that looks awful just because time series needs to be continuous. I want to have 8:00 and 18:00 as the starting and ending points and data series should come above intervals, between 8-9-10-11 etc.. Any suggestions?I want to plot a time series frequency data sim
