Can't get a good graph

[Smoka]

Hi, I'm trying to get viewable statistic from something at work. We do something that last hours:minutes, each time we do this we write down the time it takes.
Now I try to make a graph of it but only get a stright line. I kinda want something that group 3:55 ~ 3:58 because they are so similar. And we need more paperwork if the time exceed 4:00 and a few years ago you can see that it often just took 3:55-4:00. I want to show this with the graph. Maybe a upward dent in that time span.

It's hard to explain want I want but the standard graphs only give me one line/dot for each seperate time.

Take a look at your modified workbook.

It needed X-axis names. I only charted the data where you had complete info(to line 76).

There are a couple abnormal data points(you will see the spike.

Thanks for the reply but it doesnt really show much. It plot(?) the chart as it's entered in excel. If I sort the column it will just give me an increasing line.

I made a simple picture in paint to show what I'm hoping to create.
