# PetroPlot Tutorial

# Installation

System Requirements
Any system that runs Microsoft Excel 97 (Office 97) or higher.

Open PetroPlot library:
There are two ways to open the PetroPlot.xla library:
1) Manually open the file;
2) Install it once, then it will automatically open each time Excel starts.
1) Manually open
You can directly open the "PetroPlot.xla" in Excel, and remember to "Enable Macros".
2) Install "Add-ins"
To avoid manually opening this file each time you wants to use it, you can install it through "Add-ins"
(Known problem for Mac: On some old MAC OS, the installation of PetroPlot Add-In may cause extreme long time whenever Excel starts.
If that happens, is it suggested you manually open the PetroPlot.xla instead of install the Add-In.)
Step 1. In Microsoft Excel, open "Tools" menu bar, click "Add-Ins" button
Step 2. click the “Browse” button to locate the PetroPlot.xla file.
Select the PetroPlot.xla
Step 3. Find "Petrology Plot Tools" (or “PetroPlot”) and select it. Click the "OK" button.

Active PetroPlot library:
Now under "Tools" menu bar, there should be a button called "Active PetroPlot"
Click “Active PetroPlot" to activate “PetroPlot” Menu bar.

Close and uninstall PetroPlot
You can hide the “PetroPlot” menu by clicking the “Close PetroPlot” button.
Notices that the PetroPlot library is still open.
If you want to uninstall it, go to "Tools" --> "Add-Ins...", then deselect the "Petrology Plot Tools" option.
