We have optimized the memory consumption in v2.3 and it is working in the latest version. We will further check possibilities to optimize it in our future versions.
In the meantime, you can try lazy-loading the charts. We tested the same using jquery.inview & it seems to perform better compared to the regular way of rendering charts. Please download this sample project for an example on rendering charts with Lazy loading.
