Bug on Contour plot on plotly

[vincent077]

Hello All,

Last week I tried to make contour plots based on XYZ data and It worked very well
However, since Friday I cannot make anymore any of those plots…
It seems it is reading the data but does not show them???

I'm sorry but the image you submitted didn't come through... Which version of this library are you using?

Sorry,

Any contour plot with any XYZ data does not show anything.
Also, I am new to Plotly and to this.

There are two kinds of contour charts: "Contour" where you need to provide a matrix for Z (the one you have above) and "2D Contour Histogram" where Z used as an optional weight but the contours are around the density of the X/Y points.

In the screenshot above you're using the former but only providing one column of data for Z so the system is unable to draw contours, you'll need at least two columns in Z

Thanks for the reply
That is interesting because I managed to do contour maps like that last week???

I'm not sure what you were doing last week... Are you using https://plot.ly/create? Last week we upgraded to a new editor, which might be causing you some confusion. It is definitely still possible to build the kind of contour plot you have screenshotted above:

I should add that in general we do not provide support for Plotly Cloud features via Github Issues like this... Questions about our product should be directed to https://support.plot.ly/ if you have a support plan or https://community.plot.ly/ if you don't... This Github Issue system is meant for users of the open-source library who are integrating it into their own product, or actively developing it :)

Thanks!
