After reading the general introduction which details how Graphical Analysis works and how it is setup, take a look at the links below to proceed step-by-step through the listed processes for using Vernier's Graphical Analysis 2.0:

Vernier's Graphical Analysis software will allow you to easily add , graph, and analyze data. Data can be manually entered in to the data table or imported from a Texas Instruments graphing calculator using TI-GRAPH LINK.

1. Open the Graphical Analysis program.

2. The following window will open up.

Entering Data
1. To begin adding data to the data table, place your cursor in the box next to Row 1, under the x. Begin typing to enter data.
2. Add the data shown to the right to the data table.
3. Click on the area above the first column of data. The following dialog box will appear. Change the name to Temperature (F). Change the units to degrees (F).Change the decimal places to 0.

4. Click on the area above the second column of data. The following dialog box will appear. Change the name to Chirp Rate (chirps/15sec). Change the units to seconds. Change the decimal places to 0.

5. The changes and the data will appear in the graph window as well as in the data table window. (See image below)

6. Save your graph so it can be used in the following skill development activities:
7. Click on File, choose Save as.. and pick the location where you would like to save your graph.
8. A dialog box will appear which will enable you to make your selection. Change the Filename from untitled to tempchirps and click OK.
Visit "Editing Graphs and Data" to learn how to change the visual look of your graph.
Data can be imported and exported to other applications using the Graphical Analysis program. First, let's look at importing data.
Importing Data from a TI Graphing Calculator

A TI-GRAPH LINK is needed to connect the calculator to the computer. Data can be imported from the following graphing calculators: TI-73, TI-82, TI-83, TI-83 Plus, TI-85, TI-86, TI-89, TI-92, and TI-92 Plus.

1. Click on File then choose Import from TI Calculator......
2. A dialog box appears which will allow you to Select Port..... Then select the lists of data on the calculator that you want to send to Graphical Analysis.

3. On the calculator, Press 2nd LINK. This will take you to a SEND and RECEIVE menu.

4. Under the Send menu, use the down arrow key on the calculator to move down to Select All - and press ENTER.

5. Use the down arrow key on the calculator to move down to list numbers ( L1, L2, etc.) that you want to send and press ENTER after each list is selected. This will place a small triangle arrow next to the lists selected.

6. Use the right arrow key to move over to TRANSMIT. The calculator is ready to transmit the data to the Graphical Analysis program. Press ENTER.

7. The graph below shows the imported data. Notice that the x and y axis are labeled L1 and L2. The axis labels need to be edited to reflect the type of data which is imported.

Importing Data from Other Applications
Data can be imported from almost any other program by simply selecting the data and choosing Copy from the Edit menu. Once the Copy command has been executed, the data is saved on the clipboard. Place your cursor in the data table window in a new Graphical Analysis window and choose Paste. The data is added to the Graphical Analysis data table.
The following steps will take you through adding data to Graphical Analysis from a Microsoft Excel spreadsheet application:
1. Select the Microsoft Excel data to be copied.

2. Select Copy from the Edit menu. The data is now copied to the Clipboard.

3. Open a new Graphical Analysis application.

 

4. Place your cursor in the box under X next to Row Num 1.

5. Select Paste Data from the Edit menu.

6. The data is now pasted into the Graphical Analysis data table.

7. To review how to edit the x and y axis, take a look at "Entering Data." In addition, review "Editing Graphs and Data" to edit the graph display.

Exporting Data from a Graphical Analysis Application
Data can also be exported from Graphical Analysis to other programs. For example, highlighting a data table in Graphical Analysis and copying it to the clipboard, will allow for pasting into a word processing application or another spreadsheet application such as Excel.
1. To copy a data table to be used in a word processing application, select Copy Window from the Edit menu. The data is now copied to the Clipboard.
2. Place your cursor in the word processing document where you want to put the data table. Select paste from the Edit menu or hold down the Control key and press V.
To copy data to a spreadsheet application such as Excel, follow the steps outlined below:
1. Select Copy Data from the Edit menu in the Graphical Analysis application. The data is now copied to the Clipboard.
2. Place the cursor in cell A1 of the Excel spreadsheet.
3. Select Paste from the Edit menu.
4. The data is now pasted into the Excel application where it can be further analyzed.
