Thumbnail not updating


i am trying to automatically submit plots to chartstudio and send preview images of the plots via mail.
To achieve this, i am adding the link to the plot +.png in the html document im sending.
The problem is that the thumbnail or image is not updating if i am updating the plot.

In other cases (like in no thumbnail is availiable if i am looking for the .png. (see In addition no thumbnail is shown in the ‘My Files’ overview in chartstudio.

Does anyone know why this happens and what i could do to get the links to the images?


Ok i think i figured it out.
I uploaded versions with reduced data. Now the previews are availiable.
It is not important if if the data is visible in the first place or is hidden and can be made visible later on.
