i have a timeseries with every two second a ping made which gives 1ms back

Sorry false alert, i found them there are some peaks in the data set. But how to i manage that the left scale starts with 0 not with the lowest number?

a.children(1).data\_bounds=[2000,0;20000000,9];  
a.children(2).data\_bounds=[2000,0;20000000,9];  
a.children(3).data\_bounds=[2000,0;20000000,9];  
this works only on the first graphic bzw on the last graphic in the image

Stackedplot doesn’t work with subplot.
