It is for the financeChart.
And, I have found the VB.NET demo, it is 'Interactive Financial Chart'.
Thanks!! |

Hi C.H. Gim,
ChartDirector for ASP/COM/VB supports viewport. It is demonstrated in the zooming and scrolling examples:
https://www.advsofteng.com/doc/cdcom.htm#zoomscrollintro.htm
https://www.advsofteng.com/doc/cdcom.htm#zoomscrolldemo.htm
However, ChartDirector for ASP/COM/VB does not have the ViewPortControl for VB6. The ViewPortControl is a control to manipulate the viewport. You can always use other controls to manipulate the viewport, such as the chart itself (you can drag a rectangle on the chart to zoom in), scrollbar, arrow buttons, sliders, etc. They are demonstrate in the sample code that comes with ChartDirector. There is also a "concentric rectangle control" demonstrated in "Zooming and Scrolling Demonstration (2) (Windows)", which is in fact a preliminary version of the ViewPortControl.
