Hi Dennis,
As ChartDirector supports many chart types and features, we are unable to produce
examples for all possible chart type and feature combinations. Our examples are designed to
demonstrate individual ChartDirector chart types and features. You may need to develop
code to integrate them into the chart you need.
I suggest you may start by modifying the "Zooming and Scrolling with Track Line (1) (QT)"
sample code into a finance chart. There are several examples in this forum that you may
use as a reference (they are not in QT/C++, but the code is very similar). For example:
http://www.chartdir.com/forum/download_thread.php?
bn=chartdir_support&thread=1377713024#N1378487666
After that, you can modify it into a realtime chart. In ChartDirector, a realtime chart is a
chart that is periodically redrawn with the most updated data. So you just need to add a
timer to redraw the chart periodically. You may use the same or another timer to update
your data.
