datatip gives same x value for different samples
显示 更早的评论
Here is a simplified example of my problem. How can I get tooltips to show X 500000, X 500001, X 500002, etc.? Instead it shows X 500000 for all of these points. When the number of points is large enough, tooltips does not give correct integer sample number.
x = 1:1e6; % sample number
y = (-1).^x;
plot( y,'.' ); ylim( [-1.5 1.5]); xlim([500000 500020]);
title('R2020a: Tooltip shows X 500000 for all the points')

Hey Paul,
I am using the R2021b and I see the datatips properly, but you can play with the last two lines to get your desired output.
x = 1:1e6; % sample number
y = (-1).^x;
lineHandle = plot( y,'.' ); ylim( [-1.5 1.5]); xlim([500000 500020]);
title('R2020a: Tooltip shows X 500000 for all the points')
dt = datatip(lineHandle, 500010, 1);
% You can play with format specification to get the desired output
lineHandle.DataTipTemplate.DataTipRows(1).Format = '%6d';
lineHandle.DataTipTemplate.DataTipRows(2).Format = '%6d';
% lineHandle.DataTipTemplate.DataTipRows.Format is a comma separated list,
% I never remember how to assign to it

It has a different name in R2020a: https://www.mathworks.com/help/releases/R2020a/matlab/ref/matlab.graphics.datatip.datatiptextrow.html
