How can I make OxyPlot adjust zoom when calling PlotView.Invalidate? -

i have problem oxyplot follows:

i create new plotview , attach plotmodel axes when program starts.

in program, user can open file, interpreted , plotted in plotview control.

to display new series, do

myplotview.invalidate(true); 

this display data on in plot, oxyplot not perform zooming. how can pan , zoom automatically, such plot covers whole plotview?

i tried set

 myplotview.model.axes[0].dataminimum = somevalue1     myplotview.model.axes[1].dataminimum = somevalue2     myplotview.model.axes[0].datamaximum = somevalue3     myplotview.model.axes[1].datamaximum = somevalue4 

but nothing happens.

axes calculates viewminimum , viewmaxium (the real thing watching) if minimum , maximum not specified, can set them double.nan before resetting, viewminimum , viewmaximum calculated based on dataminimum , datamaximum

foreach (var ax in _plotmodel.axes)     ax.maximum = ax.minimum = double.nan; plotview.resetallaxes();  

also if changed data points, must call plot.invalidateplot() dataminimum , datamaximum gets updated too.
