Thanks for contacting Syncfusion Support.
We have checked with your query and would like to let you know that we can’t set the value less than 1 for SizeX and SizeY values of the panels. We would like to let you know that the Dashboard layout component is a grid structured layout that renders based on the parent element’s dimensions (height and width). The columns property is used to define the number of cells per row which split the parent element width into equal halves based on number of columns (for eg. if parent element width is 600px and column value is 3, each panel will have 200px width and 200px of height). So we suggest you to adjust the number of columns in the dashboard layout component to achieve you requirement at your end.
Please check the below documentation link for further details.
