How to Change the value of The Y and X axis In Calc?

I am trying to make a double Line graph in calc, And I know how to do everything except edit the X and Y Axis values. I need to do this a it is for a science lab, and my line graph must have the correct values.

Please help!

PS: Im using the Mac version.


Do you mean a Double Line graph as is shown on this page?

If so, double-click the chart to select it. Then on the main menu, pick Format->Axis->X-Axis or Y-Axis. Choose the Scale tab and uncheck the automatic boxes for Minimum, Maximum, Major and Minor intervals. Enter your desired values.

Or with the chart selected, right-click on one of the axis lines and pick Format Axis from the context menu and proceed as above.
