Hello,
is there a possibility to make a color fill (3D) plot without interpolating? I would like to see only the real values of my data in the plot, but cannot find out how.
Many thanks! |

If I go to Plot Datails --> Click on Fill --> new window opens:
"color generation with interpolation". It's not an option that I could change.

Fill piece by piece or colormap only affects the surface coloration.
thank you dear Greg,
How can I fill piece by piece? I don't see that option. I use OriginLab 9.1 .
Well, I am talking about surface coloration: that seems to me to be interpolated.
I plot "color fill" directly from XYZ. Then I set levels from 0 to hundred. I am sure there is an interpolation in the coloration: I see even values equal to -1 (these are values which are not interesting for us). Color fill displays some wrong values in the neighboring fields close to zero. My smallest values however is 27! And I see much more points than my data would allow.
I would like to see the values of my data only. I do it now with scatter bar, which works. I think Origin Colormap is more elegant.

thank you dear Zheng,
for now, I am working with scatter bar. It works, but I would prefer color fill.
Now I tried to find the set mentioned by you, but didn't find those options. I tried it from my "color fill" and "3D bar"; then plot details and fill. I don't see the rest (Front Surface to be Fill piece by piece) |

Hi,
Then how about set: Plot Detials dialog, Fill tab, Front Surface to be Fill piece by piece?
Sorry I missed this before.

With bar width be 100%.

Unfortunately, it doesn't work well for my purpose. |

thank you very much for the fast answering, Zheng. That could indeed be an option, if it is possible to set maximum and minimum values which I want to display. I will try it out tomorrow, since I have no Origin at home.
However, I think color map would be better for my purpose. So, if any one is knowing a way, I would be very thankful. |
