Hello all...I am using qwt 6.0.1 on linux and qt 4.7..I am doing real time plotting using incremental painting as shown in oscilloscope example..But in my case i am having many qwtplot widgets for plotting..My layout is in such a way that only 1 plotwidget is visible at a time.I use page up and page down button controls to go to the next plot widget.i.e.,I am adding only 1 plotwidget to the layout and hiding the remaining plot widgets..when i do page down,i will show the next plot widget and hide the remaning widgets..The problem i am facing is i am not able to do painting on the hidden plot widgets..i am calling a function every 1 second to plot on all the plotwidgets..but the widgets which were hidden are not getting painted..only the current visible widget is getting painted..When i use page up/down button and go to the other plot widget,then from that point of time painting is started on the current visible widget..my axis range is fixed and i should be able to see the plot right from the starting time i.e., from lower limit of scale..But i am not able to update the plot during the time it was hidden..how to enable painting on plotwidgets which are hidden?
