Inaccurate data in datatips of MATLAB plot

I have 3455297x1 matrix, when I try to plot it and check the datatips, the datatip shows inaccurate x axis values.

I am using R2020a. Can I change some settings to get the accurate data in datatips?

Thanks.

fig = figure; 
plot(1:3455297,1.026*ones(1,3455297))

X=datacursormode(fig);
X.UpdateFcn = @myupdatefcn;
