|-
|| 00:34
|| To record this tutorial, I am using

'''Ubuntu Linux''' 16.04 OS

|-
|| 00:43
|| '''Grace version''' 5.1.25 and 

|-
|| 00:48
|| '''Gedit text editor''' 3.18.3

|-
|| 00:55
|| To follow this tutorial,  Learners should be familiar with the '''Grace''' interface.

|-
|| 01:02
|| For the pre-requisite tutorials, please visit this website.

|-
|| 01:07
|| A '''Grace''' project file, required for this tutorial is provided in the code files link.

|-
|| 01:15
|| Let us go to the '''Desktop'''. 

|-
|| 01:18
||I have saved the '''Grace''' project file on my '''Desktop''' directory as '''line dot agr'''.

|-
|| 01:27
|| Let us open '''Grace'''.

|-
|| 01:30
|| Press the '''Windows''' key on keyboard. 

|-
|| 01:34
|| Type '''grace''' in the search form and press '''Enter''' to open '''Grace'''.

|-
|| 01:40
|| Go to '''File, Open''' to open a '''Grace project'''. 

|-
|| 01:45
||In the '''open project''' window, change directory to '''Desktop'''.

|-
|| 01:51
|| Notice the file '''line dot agr''' in the selection box.

|-
|| 01:57
|| Select this file and click on '''OK''' to open the project.

|-
|| 02:03
|| You may get an error message on fonts. 

|-
|| 02:07
||Please close the alert pop-up dialog box.

|-
|| 02:12
|| We can see a graph representing the data.

|-
|| 02:16
|| '''X''' and '''Y''' limits on the graph have changed from 0 to 10. 

|-
|| 02:23
|| Place the cursor on the line and double click to open '''Grace: Set Appearance''' window.

|-
|| 02:30
|| I will close this dialog box by clicking on the '''Close''' button.

|-
|| 02:36
|| This option can be also be opened using the menu bar.

|-
|| 02:41
|| Next, open the set appearance window.

|-
|| 02:45
|| Go to '''Plot''' menu and select '''Set Appearance'''.

|-
|| 02:50
|| I will drag the set appearance window for better view.

|-
|| 02:56
|| Since only a single dataset is loaded, it is highlighted in the '''Select set''' text box.

|-
|| 03:05
|| Look at the various settings in the '''Main''' tab.

|-
|| 03:09
|| By default a solid line plot appears in the graph. 

|-
|| 03:15
|| This style can be changed under the '''Line properties''' section.

|-
|| 03:21
|| To change the style of a line, click on the '''Style''' drop-down.

|-
|| 03:27
||Select dotted line option.

|-
|| 03:31
|| Click on the '''Apply''' button.

|-
|| 03:34
||Notice that solid line has changed to dotted line.


|-
||03:39
|| Click on up black triangles to increase or decrease the width.

|-
|| 03:45
|| Click on the '''Apply''' button.

|-
|| 03:48
|| We can change the colour of the line by selecting '''Color''' menu. 

|-
|| 03:53
|| I will choose '''red''' color. 

|-
|| 03:56
|| Click on the '''Apply''' button.

|-
|| 04:00
|| And observe the changes in the graph.

|-
|| 04:03
|| Next, let’s add symbols.

|-
|| 04:06
|| Under '''Symbol properties''' option, go to '''Type''' and click on the drop down.

|-
|| 04:12
|| Select the desired '''Symbol''' shape. I will select '''Circle'''.

|-
|| 04:18
|| To adjust the size of the symbol use the '''Size''' slider.

|-
|| 04:23
|| I will drag the symbol '''size''' slider to 40. 

|-
||04:29
|| Next, click on the '''Apply''' button.

|-
|| 04:32
|| Data points are represented as circles on the line.

|-
|| 04:37
|| Now click on '''Symbols''' tab to change symbol properties.

|-
|| 04:42
|| Under '''Symbol fill''', click on the '''Pattern''' drop-down.

|-
|| 04:47
|| Select the '''Solid''' pattern picture to get filled symbol.

|-
|| 04:52
|| Click on the '''Apply''' button.

|-
|| 04:55
|| If the data points are closely spaced, we can skip specified symbols for clarity.

|-
|| 05:03
|| Click on the arrow triangle of '''Symbol skip''' as required.

|- 
|| 05:09
|| Click on '''Close''' to exit the '''Grace: Set Appearance''' window.

|-
|| 05:16
|| Now we will fine adjust global limits.

|-
|| 05:20
|| Go to '''Plot''' and select '''Axis properties''' to open '''Grace: Axes''' dialog box.

|-
|| 05:28
|| In the '''Edit''' drop-down, choose '''X axis'''.

|-
|| 05:23
|| Select start and stop of the '''x-axis''' limits to be displayed as -1 to 10.

|-
|| 02:42
|| Click on the '''Apply''' button and observe the changes in the limits of the '''x axis'''.

|-
|| 05:48
|| Next, let's add axis labels. 

|-
|| 05:52
||Under '''Axis Label''', go to '''Label string''' text box, and type '''x-axis'''.

|-
|| 05:59
|| Click on the '''Apply''' button to see the changes.

|-
|| 06:03
|| Under '''Tick properties''', type 4 for '''Major spacing'''. 

|-
|| 06:07
|| And type 2 for '''Minor ticks'''. 

|-
|| 06:11
|| Click on the '''Apply''' button.

|-
|| 06:14
|| Notice the changes in the graph. 

|-
|| 06:17
|| To format '''y axis''' properties, select '''Y axis''' in '''Edit''' drop-down.

|-
|| 06:23
|| Choose to '''Start''' at -1 and '''End''' at 11. 

And click on the '''Apply''' button.

|-
|| 06:31
|| Axis limits of '''y-axis''' in the graph change accordingly.

|-
|| 06:37
|| In '''Label string''' textbox, type '''y axis''' and click on '''Apply''' to add '''y axis''' label.

|-
|| 06:46
|| Next we will change '''Major spacing''' and '''Minor ticks'''.

|-
|| 06:52
|| Type '''4''' for '''Major''' spacing and '''2''' for '''Minor''' spacing of axis tick marks.

|-
|| 06:59
|| Click on '''Apply'''.

|-
|| 07:01
|| Now we will go to Tick marks tab.

|-
|| 07:05
||Under '''Tick marks''' tab, we can see '''Pointing''' and '''Draw on''' drop downs.

|-
|| 07:13
|| In the '''Draw on''' drop down choose tick marks on '''Normal side'''. 

|-
|| 07:19
|| Click on '''Apply'''.

|-
|| 07:21
|| I will do this for both '''x''' and '''y''' axes.

|-
|| 07:25
|| These help to extend tick marks on both sides of the graph or on one side.

|-
|| 07:33
|| Let's select '''Draw grid lines''' for x-axis.

|-
|| 07:38
|| Click on '''Draw grid lines''' check-box for '''Major ticks''' and for '''Minor ticks'''. 

Click on '''Apply'''.

|-
|| 07:47
|| Select '''y''' axis in '''Edit''' Drop down.

|-
|| 07:51
||Check box for '''major ticks''' and for '''minor ticks''', for '''y''' axis.

|-
|| 07:59
|| Click on '''Apply'''.

This shows grids like a graph paper.

|-
|| 08:05
|| I will uncheck the box for Major and minor ticks grid.

|-
|| 08:10
||Click on '''Apply''' to remove the grid.

|-
|| 08:14
|| I will do this for both '''x''' and '''y''' axes.

|-
|| 08:18
||In the '''Edit''' drop-down choose, '''X axis'''.

|-
|| 08:22
|| Uncheck the box for '''Major ticks and minor ticks'''.

|-
|| 08:27
||Click on '''Apply''' to remove the grid.

|-
|| 08:31
|| Please try the following.

Under '''Axis Label & bar''' tab, change the font style and color of the font.

|-
|| 08:44
|| Click on '''Close''', to exit the '''Grace:Axes''' window and observe the changes.

|-
|| 08:51
|| Let's add a title to the graph. 

|-
|| 08:56
|| Go to '''Plot''' and select '''Graph Appearance'''.

|-
|| 09:00
|| The '''Graph: Appearance''' window opens.

|-
|| 09:04
|| In the '''Main''' tab, go to the '''Titles''' form. 

|-
|| 09:08
||Type the title of the graph as,'''Linear Graph'''.

|-
|| 09:12
|| Click on '''Apply'''.

|-
|| 09:14
|| Under '''Titles''' tab, notice the option to change the font type. 

|-
|| 09:20
|| Character size can be changed using the slider.

|-
|| 09:25
|| Various colors are available in the color option.

|-
|| 09:30
|| I will use the default values here. 

|-
|| 09:35
|| Click on '''Close''' to exit.

Observe the changes in the plotted graph.

|-
|| 09:41
|| Let us save the file with a different name.

|-
|| 09:45
||Click on '''File''', '''Save as''' to save the changes in the project.

|-
|| 09:51
|| Change to '''Desktop''' directroy.

|- 
|| 09:54
|| In the selection textbox change the file name. 

|-
|| 09:59
|| I will type, '''2dplot dot agr''' and click on '''OK''' to save the project.

|-
|| 10:07
|| Select '''File''', '''Exit''' in menu, to close '''Grace'''.

|-
|| 10:13

|| Adjusted global limits

|-
|| 10:34
|| Adjusted axis tick marks and grid and

Added title to the plot

|-
