00:01 Welcome to the tutorial on Overview of Grace.
00:06 In this tutorial, we will learn about,
00:11 The Grace program
00:14 The Grace parent website
00:17 Online example files and forks
00:21 Qtgrace fork website
00:25 Grace project file structure and Benefits of Grace
00:32 We will also play excerpts of Grace tutorials, available on this website.
00:40 To record this tutorial, I am using

Ubuntu Linux 16.04 OS

00:50 Firefox web browser 70
00:53 Gedit text editor 3.18 and
00:59 A working internet connection
01:02 To follow this tutorial, Learner should have knowledge of basic Mathematics.
01:09 The files used in this tutorial are available in the Code Files link.
01:15 Please download and use them while practising.
01:20 Grace is a graphical 2D plotting program, for graphing and data fitting.
01:27 The official website of Grace is shown here.
01:33 Open your default web browser and go to the Grace website.
01:41 A web page opens. We will learn about the Grace parent website.
01:47 Scroll down the page.

Notice the details about Grace in the page.

01:54 Go back to the top of the page.
01:57 Click on the Gallery link.
02:00 From here, we can download several Grace example projects and output files.
02:07 I will click on charts.png.
02:11 Notice the different types of graphs, Grace can draw for you.
02:16 You may pause the video and explore the example files on this page.
02:22 They are drawn in various plotting styles.
02:26 Go back to the Grace homepage.
02:29 Click on the Related projects and links on top of the page.
02:34 The page refreshes.

Scroll down the page.

02:40 Notice the section, which lists, Projects using Grace as plotting backend.
02:47 Many popular science programs are listed in this section.
02:52 These programs incorporate Grace for their plotting needs.
02:57 Scroll up the page to Forks or Modifications link.
03:03 Due to the high popularity of Grace, many forks and modifications are available.
03:10 There are several options for the user here.
03:15 Windows users may use the QtGrace fork.
03:20 Click on the Qtgrace link.

Let’s go to Qtgrace website.

03:27 QtGrace can be downloaded from this site.
03:31 Qtgrace is a fork of Grace with Nokia Qt SDK tools.
03:38 This is a developer tool with the ability to create applications for various OS.
03:45 QtGrace has a few added features compared to it’s parent, Grace.
03:51 Now let’s open a Grace project file.
03:55 Go to Desktop. Notice the file, line.agr.
04:01 This is a Grace project file.
04:04 This file is provided to you in the Code files link of this tutorial.
04:10 Open this file using a text editor.
04:14 I will open the file in gedit text editor.
04:19 Windows users may use notepad or wordpad software.
04:25 The graph projects are written in a text format by Grace.
04:30 Scroll down to view the project file.
04:33 Grace project files are written in a simple text format.
04:38 Hence, the projects files can be made programmatically, without the Grace GUI.
04:45 Close the file by clicking on the x sign.
04:49 Who can use Grace.
04:52 Teachers & students can use Grace for various types of data analysis.
05:00 Students can analyse, laboratory generated data or for data fitting.
05:07 Teachers may analyse student statistics on marks or attendance.
05:14 There are several benefits of using Grace.
05:18 Grace is widely used by the scientific community.
05:22 The graph can be incorporated programmatically.
