I have tried several time to obtain like this exemple (Look 'Thumbnail mode'):


This is my program:
     graph = new RGraph.Line({
         id: 'cvs',
         data: [4,6,8,7,9,4,3,8,7,4,5,5,5],
         options: {
             labels: ['Fry','Hav','Jim','Moo','Io','Olga','Tim','Gaz','Jake','Pippa','Lou','Fred','John'],
             contextmenu: [['Zoom in', RGraph.Zoom]],
             title: 'Chart with zoom (context-menu, annotatable)',

             zoomDelay: 15,
             zoomFactor: 1.6,
             zoomMode: 'thumbnail',
             zoomVdir: 'center',
             zoomThumbnailWidth: 100,
             zoomThumbnailHeight: 100,


But doesn't work, I don't know why.

Hi there,

Thumbnail zoom was removed years ago. It didn't really serve a good purpose and was a bit gimmicky.
