As indicated in the figure：plots are supported by the Quantitative layout charts，What should I do to get this chart? Is there any extension?
thanks you !

There are many Slicer tutorials - which one is this exactly (can you provide a link)? What would you like to achieve?
Time/intensity plots can be displayed using Multi-volume explorer module (bundled with Slicer). Since it seems that you are following a tutorial on quantitative reporting, you may need to install Quantitative Reporting extension to access some demonstrated features.
“Charts” are replaced by “Plots” in Slicer. See more information on plots here: [https://www.slicer.org/wiki/Documentation/Nightly/Developers/Plots](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Plots)

I follow the ppt guide step by step, but I don’t know how to get this plot when I use the Slicer ruler to spend a line in the brain image.Can you give me some detailed steps?
thanks Prof.Lasso!

Sorry to bother you, I have solved this problem，[https://github.com/fedorov/MyFirst3DSlicerExtensionTutorial](https://github.com/fedorov/MyFirst3DSlicerExtensionTutorial)
When I clicked on the Apply button of the LineIntensityProfile extension, I didn’t get the above plots because I used the first Part1snapshot. When I switched to Part1snapshot4, I got the results I wanted.
Thank you very much for your help.
