Guys:
We are developing a charting app in which we have to plot certain amount of data using the standard API for Esignal and a third party ActiveX Component.
Right now we are querying a symbol and specifying a starting date. Let's say we pull 1 day's worth of data, then, we will zoom in to our charting component to only show the last 3 hours.
I am curious as to how the Esignal Desktop app does it. How much data gets out on the initial query and how much data gets actually plotted? and also, do you re-plot your chart every time you pan on the x axis? do you query the data everytime you pan?
Thanks,
Manuel Oblitas
