You can also have a look at our Demo application >> ChartView >> Chart Types >> Stock Series example. Usually, the Demo application is located in the installation folder of the suite which can be found at the following path: C:\Program Files (x86)\Progress\Telerik UI for WinForms R2 2019\Examples\QuickStart\Bin
I hope this information helps.
