XY scatter plot with dates in the X axis

XY scatter plot with dates in the X axis

Hello,

I have two columns. The first columns are dates. The second column are values. The dates are not evenly spaced, eg. between two points there might pass one week, whereas between two other points there might pass two months.

When I use a XY scatter plot in OpenOffice, the points are aligned according to the date, ie. not necessarily equally spaced. However, in Zoho Sheet, the points are aligned with equal separations even if the time differences are not equal. Is it possible that Zoho Sheet aligns the points according to the date?

Thank you in advance
Aitor
