Contour Levels

[cdimaria]

I have created a 3d scatter plot from some data representing various thicknesses. The data group has an aim thickness along with a min and max. I would like to set up the contour levels so that if a value is above the max it is represented by one color, below the min it would be a second color and if between min/max it would be a third color. Is this possible? If yes, how?

Yes, it is possible, though not as direct as you'd probably like and the legend will show values you don't necessarily care about.

Right-click on your plot and select Scatter Plot Options. Under Color Based On select Z value. Set Intervals to 3. For the lower limit use min - (max-min). For the upper limit use max + (max-min). This will result in the middle level ranging from min to max. As mentioned above, the legend will show the lower and upper limits; if you want to delete those labels you'll unfortunately need to edit an image of the plot in a paint program.

David,

Thanks for the quick reply. I'm generating the plots in .NET2005 and displaying them on a picturebox. Are there cooresponding commands I can send? Sorry if this is obvious, I'm a newbie for this product. BTW, great stuff! I've been looking for weeks for something like this.

Thanks for your comments.

[ColorBasis(0)] bases colors on Z value.
[ContourLevels(numlevels,lo,hi)] assigns contour levels to Z values. You want numlevels=3, lo=min-(max-min), and hi=max+(max-min)
