Scatter plot

[fhelen]

Hello,
Fist off all, thank's a lot for your great job; Xplot is exactly what i needed for my daily work;
I have recently installed Xplot in conda environment:
xeus ; 0.18.1
xeus-cling ; 0.4.10
xplot ; 0.11.0
xproperty ; 0.8.0
xtl ; 0.5.2
xwidgets ; 0.16.0

But i can't build scatter plot:
Here is error compilation message when i'run your basic test (notebooks/xscatter.ipynb) inside my conda env:

Do you have any idea to help me how to fix the problem?
Thank by advance

just in case, did you use a C++14 notebook? Or C++17?
