Dear community experts，

I just recently used 3D slicer and have some simple questions to ask

I want to enable the color bar on the 3D slicer, as shown in Figure 1, there is a color bar showing the size of the color corresponding to the value of YValue.

 ![3Dslice](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/b/a/ba3a2b3017927e61ad468cfb7103eaf69d160edc.png)

I saw some instructions on “color legend” from the manual  
[https://slicer.readthedocs.io/en/latest/user\_guide/modules/colors.html#show-color-legend](https://slicer.readthedocs.io/en/latest/user_guide/modules/colors.html#show-color-legend)

But follow the action if you see the “show color legend” option.

What’s the reason? Looking forward to an answer.

your sincerely,  
Yuri

Dear community experts，

I’ve found the answer to the previous question.  
I recommend updating from version 4.13 onwards. This will make it easier to find the “color legend”
