1970 in X-Axis when no series visible

Hello,When I make invisible all the series in a chart, the date that the chart has in the X-Axis is 1970. I would like to maintain the old date. Is this possible?Regards, David.

Hi David, 
Thanks for using Syncfusion products. 
You can achieve this requirement by using the below solutions. 
1. By setting Minimum and Maximum to PrimaryAxis, you can achieve this requirement. Please refer the code snippet below. 
Code Example: 
   <chart:DateTimeAxis Minimum="1/1/2015" Maximum="5/1/2015"/> 
2. We suggest you to set Opacity to ChartSeries instead of collapsing the series visibility. Please refer the code snippet below. 
Code Example:  

series.Opacity = 0.1; 
We have attached sample for your reference which can be downloaded from the following location. 
Please check the attached sample and let us know if you need further assistance on this.

The second solution does not fit to me since I can have more than one serie, and I need to make visible/invisible some of them to see others (changing the Y values).

So I tried with the first option. The problem is that when I try to put the minimum and maximum to their default values (null) in order to compute the series by themselves I encounter with this exception:

A code snippet so you can understand:

               if (allSeriesInvisible)

                    {//just for not show 1970

                        ((DateTimeAxis)chart.PrimaryAxis).Minimum = rangeNavigator.ViewRangeStart;

                        ((DateTimeAxis)chart.PrimaryAxis).Maximum = rangeNavigator.ViewRangeEnd;



                    {//default values

                        ((DateTimeAxis)chart.PrimaryAxis).Minimum = null;

                        ((DateTimeAxis)chart.PrimaryAxis).Maximum = null;

Hi David, 
We were able to reproduce the reported issue in iOS platform. We have already fixed this issue. The fix will be included in our upcoming Volume 3, 2017 release which is expected to be rolled out by the first week of August. 
To overcome this issue, we kindly request you to set new DateTime values to Minimum, Maximum instead of setting null. Please find the code snippet below. 
Code Example: 
(Chart.PrimaryAxis as DateTimeAxis).Minimum = new DateTime(2015, 01, 01); 
(Chart.PrimaryAxis as DateTimeAxis).Minimum = new DateTime(2015, 01, 01); 
Please let us know if you need further assistance on this.
