Attached figure is a contour plot with
x-axis as distance [40x1]
y-axis as time [40x50000]
and we are plotting contour for velocity [40x50000]As we can see in the 2nd figure contour22 (zoomed view) the data is not good in that region. How can I identify that region’s data points, remove and replace with interpolated points so that I can get a smooth curve. Can you detail me the steps to do this please. Thanks.
A quick method of replacing data in plots is using brush tool on toolbar. Click and drag to select, right-click to view data brushing options.
Programmatic brushing can be done by selecting data using logical indexing. Removing this contour might need to replace corresponding rows and columns with NaNs; but that would result in discontinuous contour. Best way to ensure bad data gets replaced by interpolation resulting in a smoother contour is removal of rows & columns corresponding to bad contour.And how exactly will we identify this bad points in the matrix considering its large size. Thanks
By defining what’s “bad” and using logical indexing.
