Wrong axis range after append data by flow()

I already have data displayed in the graph (high Y values). Using **flow()** to reads new (much lower) values and old high values are discarded because the length parameter is used.
The X and Y axis range is set incorrectly. Only when I zoom in with the mouse wheel or resize the browser window does the axis ranges be adjusted.

Is this a issue? Is there any way to force recalculated axis ranges?

Update data:
```
this.$chart.flow({
x: 'x',
xFormat: '%Y-%m-%d %H:%M:%S.%L',
columns: [
dataX,
dataY
],
length: cropLen,
})
```
