I did a test with Direct2D for better performanceI use a dynamic array to simulate incoming data, and I shift data when it reaches the right side of the rectangle to scroll the graph and display last...

<<It makes no sense to display all as a graph>> ????It is usually done every where. I did this in VB6.You collect on a graph data in one second or one day and you do not want to make any...

HiCorrect, you did not understand my example. As I explained, the example was 'The idea is to show that if you have large numbers of data points,it makes no sense to try and display them all as a graph...

Hy.No, it dont seem to be what i need. You are changing the sinus period and number of points are constant.How could i treat incoming data in this way?Is not possible to add point after point to a...

HiOK. You are aware that there is a very big difference between storing a large collection of data and trying to displaying it all in this way.By way of an example, using a simulation of incoming data...

Hy,it requires much time to see something with N=1000000.Set N=10000, with box checked you will se a growing sinusoid. From about half graph on you'll see a slowing down.If you put N=1000000, for...
