4 years ago Hi all,
I am having the same issue.
[ { _dim: undefined, _dataPoints: [], _connections: [], _selections: [], _hasMetadata: false, _mkeys: [ 'Label' ], name: 'Default Dataset', variableNames: [ 'x', 'y' ] } ] Line 29
TypeError: Cannot read property '_delX' of undefined at appendData (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/app/node-module/wpd-4.2/wpd_node.js:2844:67) at wpd.BarExtractionAlgo.run (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/app/node-module/wpd-4.2/wpd_node.js:2884:21) at digitizeImage (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/node_examples/batch_process.js:42:32) at jimp.read.then.img (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/node_examples/batch_process.js:76:69) TypeError: Cannot read property '_delX' of undefined at appendData (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/app/node-module/wpd-4.2/wpd_node.js:2844:67) at wpd.BarExtractionAlgo.run (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/app/node-module/wpd-4.2/wpd_node.js:2884:21) at digitizeImage (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/node_examples/batch_process.js:42:32) at jimp.read.then.img (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/node_examples/batch_process.js:76:69)
This is a minimum file config serialize() { return this._wasRun ? { algoType: "AveragingWindowWithStepSizeAlgo", xmin: this._xmin, delx: this._delx, xmax: this._xmax, ymin: this._ymin, ymax: this._ymax, lineWidth: this._lineWidth } : null;
Will like to get some guidance Thx
Hi Ankit,
I uploaded the reference_project.json and the image I used for testing the batch_process.js. test_files.zip
As you suggested, the reference_project.json contains a modified version of the output when getting the data through the web tool and thus all the calibration keys needed to serialise the image. However, while running the batch_process.js, we always bumped in this error:
[ { _dim: undefined, _dataPoints: [ [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object] ], _connections: [], _selections: [], _hasMetadata: true, _mkeys: [ 'Label' ], name: 'Default Dataset', variableNames: [ 'x', 'y' ] } ] TypeError: Cannot read property '_delX' of undefined at appendData (/.../WebPlotDigitizer/app/node-module/wpd-4.2/wpd_node.js:2844:67) at wpd.BarExtractionAlgo.run (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/app/node-module/wpd-4.2/wpd_node.js:2884:21) at digitizeImage (/.../WebPlotDigitizer/node_examples/batch_process.js:40:32) at jimp.read.then.img (/.../WebPlotDigitizer/node_examples/batch_process.js:74:69) TypeError: Cannot read property '_delX' of undefined at appendData (/.../WebPlotDigitizer/app/node-module/wpd-4.2/wpd_node.js:2844:67) at wpd.BarExtractionAlgo.run (/Users/Roderick/Desktop/Projects/WebPlotDigitizer/app/node-module/wpd-4.2/wpd_node.js:2884:21) at digitizeImage (/.../WebPlotDigitizer/node_examples/batch_process.js:40:32) at jimp.read.then.img (/.../WebPlotDigitizer/node_examples/batch_process.js:74:69)
No keys of the reference_project.json is entitled/provides "dim". As a result "dim" is undefined (and it could be another parameter); I think that's one of the reasons why we encounter the error "Cannot read property '_delX' of undefined". Is there any way you can transmit us:
1- a working version of the reference_project.json for the type of mrtg graph attached? or 2- a template of a working reference_project.json for the images in the GitHub repository? or 3- a pointer to all the calibration keys the file reference_project.json may contain (their format+ definition) for the tool to function properly with nodejs?
Please do not close the ticket before we finish debugging :) Thanks in advance.
