I am a new user of the mango. As shown on the graph, I am now using a ascii data source for testing. When I setup the period as 1 minute, I will receive three figures like 1 2 3 and the next minute, I will receive 3 figures again. My goal is to receive only the last figure of the 3 figures like 3 in the first period while in the next period I get a new figure like 4. However, when I choose the "Read timestamp?" frame, there is no feedback and no figures can be received. Please tell me how to make the right operation, thank you???
