Interacting with charts-2
A few months back I posted a sample on one way we can interact with charts.
Here is another way. you can try the sample here.
1. we can drag the left and right thumbs to adjust the width of the chart we want to zoom in
2. we can click in the shaded region between the thumbs and drag it to reposition it somewhere else on the chart. the details are shown in the chart below
Note: this is just a POC and not all details are taken care of
you can download the code here
