pcsoft.us.windevCopyright 2026, PC SOFT14 Jul 2015 15:28:00 Z14 Jul 2015 09:29:00 ZMy dilemma is in 2 parts. I am trying to plot data that is being collected real-time on a line chart. At any one time I wish to display only n samples. As new samples arrive the equivalent number drop off. In this way I am hoping to see a trend over time. I am also archiving the samples to a database for later analysis or replay. Under this scenario I am wishing to simulate the real-time collection and plot the data as above. So far I have the data logged, the chart drawn but I am at a loss on how to attach the chart to the data source for replay, or how to limit the display to a selected number of samples. Has anyone had any experience with this type scenario? Any pointers would be greatfully received. thanks Rob30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/53057-windev-chart-control/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)guestpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/53057-windev-chart-control-53068/read.awp14 Jul 2015 15:28:00 ZI have my viewer working in the following fashion updating a chart control developed in the IDE.
