hide zero line in a chart in jquery kendo

Question

I have a trend that checks four different time periods and the way it works is that the user must choose from a specific date to a specific date.

1. The problem I have now is that if it doesn't have data in a certain time period, it returns 0. If I want the trend not to be displayed in that section.
2. I just want the 0 data not to be shown at the end of the chart, but if I had 0 data in the middle of the chart, it should be shown.
