    Default Charts 3D, heatmap ...

    ExtJs is amazing and powerful framework - I use it to visualize our biological and statistical data in the university. Is there any chance to have native 3D scatter plots with some possibilities like rotate, zoom? And kind of heatmaps?

    Big thanks for your work.

    Hello there. For heatmaps I used nvd3 to do some stuff and I created my own heatmap. However with Extjs 5 there are some problems integrating this library, so I do not know how to solve this issue. Heatmaps are really something that is missing in Extjs

    Not sure if this is the best way but here's what I did
    - Create a new class that extends 'container' and use 'fit' layout
    - put empty html as default value
    HTML Code:
    <div id="#chartId/">
    - use listeners event 'afterRender' to integrate with 3rd party graph libary. It should be something like \
    var svg = d3.select("#chartId").append("svg")
    // other svg codes
