1、If you want to turn off the frame header, pull the Frame menu down to Edit Current Frame. A window will pop up. Click on the box next to Show Header. To see the change to take effect, click the Close button. The frame border can be turned off in a similar manner. When done, press Reading in a Data F

2、ile To read in a data file, pull the FileLoad Data File（s）. A window will pop up. Note: The filter is set to show only files with extension plt. To see all files, delete .plt from the filter and click on Filter. Tecplot can read several types of files . To do so, tecplot will run preplot on the file

3、 selected. Working with FramesTo resize a frame, click on the arrow button in the tool pallate on the left side of the screen, click on the boundary of frame, Resize handles will appear on the frame as shown in the following figure. Using the left mouse button, drag any these resize handles. To move

4、 a frame, choose the arrow button in the tool pallate click on the boundary of the frame that you want to move. Now move the cursor to the edge of the frame, but not on a resize handle.

6、frame. As shown in the following figure, either frame can be modified. Tecplot GraphsTwo Dimensional Graphs Tecplot is very flexible when drawing graphs. It can do the following, the ones with links are discussed in this document. Basic XY Plots Assign a variable to an axis Change the length and sca

7、le of the axes Plot multiple data sets. Plot multiple graphs, multiple axis Scatter plots , with choice of symbols. 3D graphs To draw a graph using tecplot, just read in your one dimensional data . The graph will appear similar to the one shown below. There are many things that you can do with the g

8、raph. Click on the Mapping Style. button. If you dont see the button, double click on the graph. When you click on the Mapping style. button, you will see the following. From this menu, you can control how the graph is plotted. The various features are broken down by category: Definitions, LinesCurv

9、es,Symbols, . To select the category, click on the appropriate button. The categories, definitions, lines and symbols are discused below. Definitions: You can assign a variable to the x-axis and to the y-axis. To assign a variable to the y-axis, just click on Y-Axis Variable. A window will pop up. C

10、hoose the variable that you to use for the vertical axis. The x-axis is handled in a similar manner. Lines: Select the category to set line color, line width, line style （Solid, dotted, dashed, .）, line color and more. Just point and click. Symbols （Scatter Plots）: To show a symbol （square, circle）

11、at the data points, click on the box next to in the upper left corner of the tecplot window. If you just want to see symbols - no line connecting the points - unselect the in the upper left corner. In the Mapping style window, click on . You should see the following. From here, you can select the sy

12、mbol shape, outline color, fill color, size and spacing. Just click on the appropriate button. To control the spacing, click on Symb Spacing and then click on Iskip=2Iskip=3 or Iskip=4 which will draw the symbol at every second, third or fourth point respectively. If this is still too many. Use the

13、Enter Index. option to manually enter a skip value. Controlling the Axis.To adjust the axes, including tick marks, labels, and length, pull the Axis menu down from Plot menu. You will see the following Across the top, is a list of axes that you can display and modify. Select the desired axis. In the

14、 above the X1 axis is selected. A modification occurs only on the selected axis. Here everything but range is easy to use, just remember Labels means the numbers that appear next to the tick marks, and Title means the name of the variable. The range option can be confusing. If one of the axis is too

15、 long, you can change the range. There are several things to set before you change the range. Unselect Preserve Length when Changing Range and select Independent If you want to change the range to zoom in, select Dependent. You may have to enter a ratio to determine the scale of the axis. You can al

16、so change the scale by selecting the arrow from the tools palette, clicking on an axis, then dragging a resize handle （a black square） to change the size of the plot. Note: This changes the scale of all axes. Preserving the length keeps the axis the same length, the scale changes. When things go wro

17、ng, pull down the ViewData Fit. Tecplot will do its best to fit the data to the frame. Plotting Multiple Data SetsTecplot can plot multiple data sets. The easiest way to plot multiple data sets is to create a file containing all the data set, each data set is a zone in the file. In the window, you c

18、an turn on and off various zones. Just click on the desired zone （that is, click on the line that are listed by map number）, or click and drag to choose multiple zones, then click on the Map Show button. You can then activate or deactivate the selected zone（s）. You can also plot multiple data sets t

19、hat are in different files. The easiest way to do this is to read all the data sets in at once. Pull the . You will see the following window. Click on Multiple Files. This window will change.
