The Contour tab is the most obvious, and it controls the type of contouring and the contour group used. The contour variable groups defined by this dialog are also used by a number of other features.įor example, in the Zone Style dialog, a number of features allow you to color by a contour group. Correct this by selecting the Legend Box and toggling on Fill to add a white background. If I zoom out to get a better picture of the surface, the contour legend is difficult to see because of the geo-referenced image behind it. See this Knowledge Base article, Changing a Contour Legend Variable Name. You can change the legend Alignment from vertical to horizontal, add custom header text, alter font size and type, or change the text color.
Simply toggle Resize automatically to scale down the height of the legend. First, you can see the legend is too tall with all the additional contour levels. This tab can also be opened by double-clicking on the contour legend in the plot. Next, I will select the Legend tab to make some adjustments. There are other options for fine tuning your color map, like changing the distribution method and reversing the direction. If I wanted to cut off my contour above or below a specified value, I could also do that with the Color cutoff toggles. See our Knowledge Base article for step-by-step instructions on importing your own color maps, Setting Customer Color Maps as Defaults. You can also load your own color map or export the existing color maps in Tecplot 360 by clicking on the gear icon. Many of the cmocean color maps will be useful for this dataset, but I will select the haline color map to match the salinity variable on the plot. These color maps are perceptually linear that is, there is a linear increase of luminosity across the scale. For this plot, we want a sequential color map, such as the default Viridis color map or one of the cmocean color maps. You can adjust the current color map, or choose a different one from the dropdown menu in the center of the dialog. You can add new contour levels at specific values by entering them in the Add Level field, or you can reset all levels by clicking Set Levels… and entering the minimum, maximum, and specified distribution in the Enter Contour Levels dialog. Tecplot 360 will automatically assign the contour levels based on the variable range in your dataset. When I choose salinity, the plot will update. You can change the variable from the dropdown menu at the top of the dialog. This opens the Contour and Multi-Coloring Details dialog. To adjust the contour, click the Contour Details button. The current variable, longitude, isn’t very interesting compared to some of the other variables in this FVCOM dataset of Massachusetts bay. More information on the Contour Details Dialog can be found in the User’s Manual Adjusting the Contour
