Why I can't display all the decimal digits in a plot?

My code converts a 2-columns string array (first image) into a 2-columns double array. After the conversion, the numbers in the matrix are cut off after the 4th decimal digits (second image) (I need 6 decimal digits) and if I plot the data, only the time axis values are cut off, this time after the 2nd decimal digit! (third figure) while the y axis data have all the 6 decimal digits required. How is it possible ?

The better solution is just update the number of decimal points in "text function". In data cursor mode, right click and select "edit text update function", in the variable output_txt= 'X: '. num2str(pos(1),4)]; update the 4 to 6 or 10, this defines total number of digits on the X axis data display. Hope this helps.

This is not the same as "format long". "format long" only affects displaying values to the command window. The Preferences affects the format of the Variable Browser.
