I made an ASP.NET MVC Project, where I use Highchart. The chart has columns and a line. Now the company I make this project for said, that they do not want to pay for a highchart license so I have to search for an alternative js chart library. The requirements are:
- it should be for free
- it should be as similar as possible to highcharts
- i need a chart with columns and a line
- i need drilldown for "data zooming"
