Origin Lab Pro 8.5.1 Why to use
To tell the truth, I also do not know the extend of that program capabilities, but think of it even now it is very comfortable to plot graphs and enter the data with this program and make us feel more comfortable than Excel , and I was said by my teacher who study on Inorganic Chemistry, that this program will be very important and useful in future, too. These two are the "why" for learning it.
I will explain the cruial things about using this program instead of Excel.
How to set up Program ?
You can download the program from this link, and in the originPro-patch folder, there is a text file which will give you directions about activating the program. And after get through of license, just do not make any update or registration, and easily start to use it. By the way, link is mine ;)
How to make simple calculations among columns like in excel ?
First thing to learn is adding the new column, quite easy. Just right-click with your mouse to an open area and select the "Add New Column" . You can also change it's long and short name but they are so easy things which is not necessary to take snapshots and upload here :)
When you just come to on top of column, mouse pointer will be a bold arrow towards down and after clicking, you will select the column in order to make process on it, from changing it's name to setting basic functions on it.
The most critical button is this "Set Column Values" one. Merely using that I do not feel any need for slow and boring Excel :) By the way, plotting issue can be done with the menu's toppest button "Plot" in this right-click list.
After clicking "Set Column Values" that window will appear. And when you click "Col(A)" at middle top of the window, it will give you the list of columns exist in your spreadsheet and you will select the one you need from there. For instance in order to add A and B's adjacent values each other, I firstly select "Col(A) " and then put an "+" from keyboard, afterthat I selected "Col(B)" and press "Ok". The result will be in the following picture :)
As you see, adjacent values, i.e. A1 and B1 are added each other at D1 and gives the result of "3" . Others are like this, too. So that's it :)
