3D manual z-axis scaling

[ledz]

Is there a way to (programmatically) force the scaling of the z-axis in a surface/contour 3D display?

Until now, I've used the logarithmic scaling option, because it makes the value 1 (the minimum value) stand out more, but this uses up many of the shades available in the color legend. I'm using a starting value of e.g. 0.1 which makes all values below 1 'disappear into the floor', which is my intention.

However, I would like to individually set the colors and the ticks of the color legend. Is this possible (and if yes, programmatically)?

Thanks in advance for any help, and have a nice weekend!

Hi ledz,

I will try to help you. What DIAdem version are you using?

Could you provide me with some sample data?

Hi Stefan,

My DIAdem version is 11.3f4653, Advanced (I think).

Sample data is below, containing my matrix data (x, y and z channels) in a zipped .tdms file.

Since "0" is my floor in the matrix, and "1" is a quite important value, since it means the rig ran through that path at least once, I would like to use a manual color scale to accentuate the difference between 0 and 1. So, 0 would be blue (0x0000FF) and 1 would be a lighter shade (0x0099FF or 0x00CCFF). The rest I would like to scale up the chromatic scale to red (0xFF0000).

Ideally, a channel akin to a tick channel would be nice, but I haven't found anything in the help file or on the net that does that (which may well mean that I did not look hard enough or just didn't see it).

Thank you for your help!

Ho ledz,

I managed to customize the colors by opening "Display.." in the conect menu, then clocking on the color item in the curve list. There you can select "Colors frtom contour tabel" in the surface tab. Then the "Contour table" tab becomes available. In there you can set the colors for indiviual intervals. With the button generate isolines you can insert smooth color transitions.
