Google Spreadsheet Graph – A very good way to present visual data is to create a chart in a Google Docs spreadsheet. Google spreadsheets not only make you build a chart from data in a spreadsheet, but also offer customization options to highlight the different data systems.
1. Select the range of data you want to include in the graph.  Select with the mouse all the data you want to include in the graph. If you want your graphic to have labels, make sure the columns and rows have headers.
An example column header: If you have a column with numbers and you want those numbers to appear in the chart as “Daily Earnings,” the first cell in that column should read “Daily Earnings.”
An example of row headers: If you have a row with city names and you want those names to appear on the chart labeled “Cities”, the first cell in that column should read “Cities.”
2. Open the “Graphics Editor”. Open the “Insert” menu at the top of the screen and select “Chart”.
3. Choose a format for your chart. Now the “Graphic Editor” will open, which contains three tabs. In the “Recommendations” tab you will have the option to select one of the four recommended charts. Clicking on any of them will preview the data sorted in that chart format. Choose one of the charts or change to the “Chart types” tab if you want to see other options.
A particular chart format may be better or worse depending on the purpose it has.  For example, if you want to show changes that have been made to certain data over time, it would be good if you use a line graph, a mini graph, or a motion graph. If you want to display one or more categories of data, try bar or column charts. If you are looking for an option that combines both concepts, it is better a combined chart. To see the name of the different chart types, hover the cursor over the image of each chart.
If you do not preview a chart format, try to place a check mark in the box that says “Change rows / columns.”  If that does not work, you may have to select a different data set or try another graph format.
