Origin Ver. and Service Release (Select Help-->About Origin): OriginPro 2024 (64-bit) SR1 10.1.0.178 (Trial)
Operating System: Windows10
Hi everyone,
just downloaded OriginLab so pardon if my question is trivial.
I have a three columns datasheet: first two cols are x-y positions, third col is speed associated with each position.
I need to plot a scatterplot with each x-y point coloured based on speed and according to a reference colorbar.
How can I do that?
Thanks in advance!!

Hello,
1. You can add a color scale:

2. You can edit the Levels in the Plot Details:

Best,
Chao

Hi,
thanks for fast reply.
I did it but:
- how can I show the associated colormap on the figure?
- if I select a different color list from the dropdown menu, I can see only a limited range of colors, i.e. the colorbar does not adapt automatically to the min and max values I have in my data file. How can I fix this?
Thanks a lot! |

Hello,
You can highlight all 3 columns and choose Plot: Basic 2D: Color Mapped.
You can double click the plot and use mini toolbar to customize the colormap further.
See https://www.originlab.com/doc/Origin-Help/Color-Mapped-Graph
Thanks, Snow
