Thanks for contacting Syncfusion support.
We are able to add the image in chart header by using SfChart’s Header property as shown in the below code snippet.
At present we are not having Footer support for SfChart. However you can add the footer(i.e. current time and page number) in PrimaryAxis header. We have prepared the sample based on your requirement. Please find the sample in the below location.
Please let us know if you need any further assistance on this.
