Blanking a corner of plot

Problem: I want to blank my contour plot only in the lower left-hand corner where x < 45 AND y < 30. Solution: You can use equations like the ones below to create a blanking variable equal to 0 only if x < 45 and y < 30. Then you can delete the extra variables {lowerx} and {lowery}. {lowerx} = max (x -45, 0) {lowery} = max (y – 30, […]

Animating points

Problem: I have some files with some scatter points animated to move in constant velocity. However, the movie shows relative motion of the scatter points making the animation appear jerky. Solution: The reason the scatter points look like they are moving relative to one another has to do with the way they are drawn on the screen. Any object drawn to the screen will be rounded off to the nearest […]

Using old text formatting

Problem: Is there any way to use old text formatting with Tecplot 10? Many of my layouts contain text with the special symbols (~ ` _ and so forth). Solution: You can add a command to the tecplot.cfg file to see the text formatted with Tecplot 9 style: $!Compatibility AllowOldTextFormatting = yes This option will let the user use both formatting types at once. It will show both lines of […]

Average of XY Mapping

Problem: In my XY Line plot, I want to show a line for the average value of one of the XY Mappings. Solution: You can have Tecplot calculate and plot the average for a line mapping: In the Mapping Style dialog Copy the line mapping and make sure the copy is shown. On the Curves page, set the Curve Fit for the new mapping to the General Curve Fit (One […]

Tecplot 10 is slower than Tecplot 9

Note: This software version is no longer supported. Download the latest release or get a free trial. Problem: For zooming or translating my contour plot, Tecplot 10 is much slower than Tecplot 9. Solution: The difference between Tecplot 10 and Tecplot 9 is that different contour levels are set. Notice what levels Tecplot 10 sets set the same levels in Tecplot 9 and see if that makes Tecplot 9 performance slower. If […]

Greek or special character in variable name or text

November 2017 Update: LaTeX Fonts are available in Tecplot 360 2017 Release 3 and later. This gives you the ability to use your installed version of LaTeX to display complex formulae and equations directly on your plots. We test against MiKTeX and TeXLive but should be compatible with other LaTeX engines. Watch the LaTeX video tutorial Problem: Some variable names in my data file include one Greek character or another […]

But when I change the label font for one frame te other frames do not change. Solution: Linking on the Between Frames page of the dialog will cause the changes in one frame to apply to all frames. Linking on […]

Skip vectors or scatter points

Problem: My data is very dense. I want to show vectors or scatter but not at every point. Solution: On the Zone Style dialog, go to the Points tab. One of the options is Index skip and this setting will apply to both scatter points and vectors.

3D Probe Calculation

Problem: What process does Tecplot use for probing in 3D? Also for streamtrace placement contour labeling linear interpolation and polyline extraction in 3D. Solution: Tecplot determines the tetrahedron that the point is inside and then does a weighted average of the data set values at the four corners of the tetrahedron to get the values at the point. This method is not the most accurate – especially if your grid […]
