@benna,
– In order to see again ALL the chart data i need to click TWICE the “ALL” button in range selector, and this happen also in your JDIfiddle example above. Try selecting, the first time the page is loadedm range 3 months and then the ALL button. You’ll see that the first time will change just the navigation bar, and with a second click also the chart data will change accordingly.
To show all the chart data, you can set the slider’s minimum and maximum to null in rangeChanged event handler. Please take a look at this JSFiddle for an example on the same.
