Description
Steps to Reproduce
1. run the attached example charts-datetime-with-model.zul
2. click the button to add another value dynamically
Current Result
1. the datetime axis is displayed using milliseconds instead of the correct dates values and also the different intervals between the dates are not reflected
2. the x-axis gets scaled completely incorrect
Expected Result
correctly rendered datetime axis and correct intervals between the value points
(same as using the workaround - setting the model after adding the data values)
Debug Info
this happens when setting the model to the chart after adding the values
Workaround
assign the model before adding values to it
