Creating a profit line chart

I just can’t seem to find a way to make a simple line chart.

I want to make a line chart of data (daily profit or loss numbers per row) I put in a column. The graph should start at 0 and then add up (or down) all the number in a line chart.

Thanks in advance

Please can you attach a sample file, and take a look in Chapter 3: Using Charts and Graphs. https://wiki.documentfoundation.org/Documentation/Publications#LibreOffice_Calc_Guide

sample.ods here is a sample of a two week period

You may play with the attached example trying to find possible settings and changing them. I edited your sample a bit to make it more realistic.

Better: Study the Calc guide, chapter 3, from http://www.libreoffice.org/get-help/documentation/ first.
