Hello Peio, You can use Microsoft Chart Controls For .NET Framework 3.5 over ZedGraph. OR Highchart (https://www.highcharts.com/). It Is One of the most widely used chart library of current time. OR other jquery chart framework JSCharts (http://www.jscharts.com/examples) Flot (http://www.flotcharts.org/) jpPlot (http://www.jqplot.com/) Charjs (https://www.chartjs.org/) Thanks Naimish

Hi, I have used Syncfusion to generate charts in one of my application but it's expensive. They have community license. You can claim it from here https://www.syncfusion.com/sales/communitylicense. Regards, Pasang
