I have a library project generated by MultiCharts and I dont know how to use that Library to test in Visual Studio 2013.
I just want to insert a symbol like "GOOG" or "CSCO" ... to display the Chart like this image below.
But I don't know how to insert symbol. Any suggestion will be highly appreciated.
If you want to change the symbol to one in your example, first right-click on the chart and select 'Format Instruments...':
Then choose a data feed (the 'Data Source' pulldown menu in the image below) and a symbol that you want to plot. In the case of your example screenshot, it will be 'GOOG' from the 'Free Quotes' data source.
Then press 'OK' to display that symbol.
By the way, in the 'Settings' tab in the 'Format Instruments' window (see image above) you can specify a symbol's resolution. In accordance with your example image, you'll need to set it to 1 day.
