I need to select the area on the chart, see example https://jsfiddle.net/aliakseimaniuk/k556wna9/. Select works perfectly, but I want to do a light modification. I want to select only using X coordinate. It means when users try to select area it should be selected with all values at Y coordinate, regardless of the cursor position. Like on the image below
Is it possible to do that way, if yes, please provide some hints how to do that? Thank you in advance.
