The embeded view in column container doesn't refresh after the window is resized

My column container has 5 embedded views. each view has a time series chart. when the window is resized(breakpoint is from large to medium), some views’ time series charts are back to original(the good views’ chart keep the data). i have a thread writing new data to the charts via parameter and those charts don’t refresh when the good views’ chart are refreshing.

I found the reason…
the view is rebuilding when the window resizes(from large to medium). the chart is back to default but the chart’s binding data is passed over from the old view…(it is the reason!). when new data is coming, if the new data is same as the old data, the view doesn’t see the change , so doesn’t refresh.
Have to force the binding data to a value in the startup event in the view… then it will refresh when new data is coming…

I used the perspective for 1 month… there are so many surprises like this…
