Hello everybody,
Yesterday I had the question to get mean gray level value into an excel sheet. After the help I managed to get it work. Now i have the following question.
I can plot in Excel but I know that matlab can do it for me.
I found the following code,
% [num, txt, raw] = xlsread('mean_gray_level_value.xlsx', 1);
% plot(num)
% num = sort(num);
% for i = 1:numel(num)
% NumCell(i) = {num2str(num(i))};
% end
% set(gca,'Xtick',1:numel(num),'XTickLabel',txt, 'Ytick', num,'YTickLabel',NumCell)
Can someone help me to plot from data of an excel sheet? the y axis must be from 0 to 255 the x axis must be the number of the analysis.
I hope you can help me,
Kind regards

You can simply read data in an Excel file using the readtable function.
Then, read the column data as X and Y variables into Matlab. ( Use the column header names in the Excel file to extract values. Please see the example below)
Use the plot function to create a plot.
%: Read the excel file using readtable function
rawTable = readtable('testData.xlsx','Sheet','Sheet1');
x = rawTable.Header1; %: get the excel column, Header1 (header name)
y = rawTable.Header2; %: get the excel column, Header2 (header name)
figure;
plot(x,y);

And if you only need a few cells of the sheet in the Excel, how can you extract them with readtable function?
Former xlsread used the last argument ['B' num2str(i+2) ':C' num2str(i+2)] to tell Matlab to search from cell B3...
THANKS
