Scatter matrix graph output is incorrect

Using the px scatter on my own data I received a strange result. The data is not plotting in the correct positions on the plot using jupyter notebook.
as you can see in the attached image it is clear that copper_AS plotted against itself should be a straight line, but is not.
I checked the data for anything weird, but it all looks clean - see attached image.
I am new to python / plotly so may be doing something stupid when importing the data from a csv.
Thanks for reporting this! It's indeed very strange. Are you able to share your data file or some other way for us to reproduce this locally?
Can do, but was going to try it with different data on a different computer first. Will also try reducing the size of the data file as well. If that doesn't work I will post the jupyter notebook and data. I am in australia, so it won't be today your time.
OK, thanks!
Will also try reducing the size of the data file as well.
@damstep It is often a good idea to find the minimal example that trigger the bug.
I tried again with a csv containing 25 rows and 12 columns, but get the same result. I am running it in jupyter notebook 5.6.0 utlisiing python 3.7.0 on a windows 10 64 bit machine. in IE 11. attached are my notebook and the cut down file.
turns out it as a windows explorer issue. My company uses it as the default due to sharepoint problems, but running it in edge works fine!
Ah, thanks for tracking that down! we'll get on it :)
