Slide Number 5

Code Files

The files used in this tutorial are available in the Code Files link of this tutorial page.

Please download and use them while practising.

Slide Number 6

Plotting Data

Why do we need to plot data?
  • Numbers written in a table do not allow visual inspection.
  • Graphs condense large data for visual analysis and inspection.
  • Data trends become easily noticebale and perceptible in a graph.
Slide Number 7

Grace http://plasma-gate.weizmann.ac.il/Grace/

Grace is a graphical 2D plotting program, for graphing and data fitting.

Official website of Grace is shown here.

Slide Number 8

Who can use Grace

  • Teachers & students can use Grace for various types of data analysis.
  • Students can analyse, laboratory generated data or for data fitting.
  • Teachers may analyse student statistics on marks or attendance.
Go to the website, http://plasma-gate.weizmann.ac.il/Grace/ Open your default web browser and go to the Grace website.

We will learn about the Grace parent website.

Scroll down the page.

Cursor on the graph image. Notice the different types of graphs, Grace can draw for you.
Go to Grace homepage. You may pause the video and explore the example files on this page.

They are drawn in various plotting styles. Go back to the Grace homepage.

Click on the Related projects and links. Click on the Related projects and links on top of the page.
Scroll down.

Cursor on the program list under, Projects using Grace as plotting backend.

The page refreshes.

Scroll down the page. Notice the section, which lists, Projects using Grace as plotting back end.

Cursor on the program list that incorporate Grace. Many popular science programs are listed in this section.

These programs incorporate Grace for their plotting needs.

Scroll up the page. Scroll up the page to Forks/ Modification link.
Cursor on the forks of Grace. Due to the high popularity of Grace, many forks and modifications are available.
Cursor on the list of forks of Grace. There are several options for the user here.

Qtgrace is a fork of Grace with Nokia Qt SDK tools. This is a developer tool with the ability to create applications for various OS.

Cursor on the Qtgrace page. QtGrace has a few added features compared to it’s parent, Grace.
Now let’s open a Grace project file.
Go to Desktop. Go to Desktop.

Notice the file, line.agr. This is a Grace project file.

Point to the file line.agr. This file is provided to you in the Code files link of this tutorial.

Please download and extract the file.

Select the file, right click, choose open with option and choose gedit. Open this file using a text editor.

I will open the file in gedit text editor.

Cursor on gedit window. Windows users may use notepad or wordpad.
Cursor on gedit window. The graph projects are written in a text format by Grace.
Scroll down the project text file. Scroll down to view the project file.

Grace project files are written in a simple text format. Hence, the projects files can be made programmatically, without the Grace GUI.

Close the gedit window. Close the file by clicking on the x sign.
