Is there a way to shift the data upwards automatically?

조회 수: 6(최근 30일)
Hi folks,
I have a graph as follows. I am looking to shift the valley (red) upwards to be in keeping with the preceeding data. Is there a way to do this automatically? I am unaware of the best method of achieving this currently.
I've attached a copy of the data for reference.

I tried plotting Height vs. Temperature, since that is what your plot shows. But my graph looks completely different from yours.
r = readtable('','Sheet','Test Piece 1-BS 1');
Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.
Perhaps make it easier for us to help you, by only uploading the two variables you are plotting above, in a MAT file?
EDIT (in response to comment):
I've uploaded the new data file. Also, this whole thing should have been a comment rather than an answer. But I'll leave it here.

The key is get a firm conceptual understanding of what defines the valley. In your original image, it looked simple, because it looked like a huge drop from one data point to the very next one. But in the dataset you uploaded that I plotted, it is not as clear.
So, before you think about how to code it, you need to make this conceptual understand that works in general for your datasets. Then I would recommend writing pseudocode for the actual algorithm steps, and then the actual MATLAB code. We can mostly be helpful in that last step.
