Hello,
I would like to read a value from json file and use these values in the plot function.
So I did some resarch and realized that there is a lib named "loadjson" and I've added into my MATLAB. But I can't read values from my json file and cannot find a solution in MATLAB answers for it.
I'm kinda new at MATLAB and I need a bit of help 🙂
Thanks in advance.
The output of my json but I cannot see the values. I would like to read Location's values (locationX and locationY)
My JSON file:
"Location": [ { "id": "0b5965e5-c509-4522-a525-8ef5a49dadaf", "measureId": "5a6e9b79-dbb1-4482-acc1-d538f68ef01f", "locationX": 0.9039769252518151, "locationY": 0.2640594070404616, "createdAt": "06-01-2021 19:38:44" }, { "id": "18714a2f-a8b3-4dc6-8a5b-114497fa9671", "measureId": "671f52bc-a066-494a-9dce-6e9ccfac6c1d", "locationX": 1.5592001730078755, "locationY": 0.5207689756815629, "createdAt": "06-01-2021 19:35:24" },
My MATLAB code:
% Setting my image and related params
img = imread('C:/plan/plan.jpg');imshow(img)min_x = 0;max_x = 7;min_y = 0;max_y = 3;imagesc([min_x max_x], [min_y max_y], img);% Load json file
data = loadjson('C:/data/default.json');disp(data)% I want to use these values into plot function.
hold on;plot(x, y, 'ro', 'MarkerSize', 5);
