Values of 0 (zero) in series are missing in line chart

[andrei-cs]

For a series having 0's as values the points don't show up in the graph when viewing the PPT in Powerpoint.

If instead of providing 0's as numerical values I provide them as strings, the chart displays properly.

Code snippets from the provided JSFiddle.

Ex: Not working Values array:

var pptx = new PptxGenJS(); var slide = pptx.addNewSlide(); var opts = { x:1.0, y:1.0, font_size:42, color:'00FF00' }; slide.addText('Hello World!', opts); var chartData = [ { "name": "Chart", "labels": [ "16-Oct-17", "17-Oct-17", "18-Oct-17", "19-Oct-17", "20-Oct-17", "21-Oct-17", "22-Oct-17", "23-Oct-17", "24-Oct-17", "25-Oct-17", "26-Oct-17", "27-Oct-17", "28-Oct-17", "29-Oct-17", "30-Oct-17", "31-Oct-17", "01-Nov-17", "02-Nov-17", "03-Nov-17", "04-Nov-17", "05-Nov-17", "06-Nov-17", "07-Nov-17", "08-Nov-17", "09-Nov-17", "10-Nov-17", "11-Nov-17", "12-Nov-17", "13-Nov-17", "14-Nov-17", "15-Nov-17" ], "values": [ 0, 0, 149, 141, 0, 0, 0, 0, 0, 0, 139, 1177, 477, 0, 0, 2578, 0, 0, 349, 0, 0, 0, 2195, 1057, 807, 0, 0, 0, 148, 241, 0 ] } ] slide.addChart( pptx.charts.LINE, chartData) pptx.save();

var pptx = new PptxGenJS(); var slide = pptx.addNewSlide(); var opts = { x:1.0, y:1.0, font_size:42, color:'00FF00' }; slide.addText('Hello World!', opts); var chartData = [ { "name": "Chart", "labels": [ "16-Oct-17", "17-Oct-17", "18-Oct-17", "19-Oct-17", "20-Oct-17", "21-Oct-17", "22-Oct-17", "23-Oct-17", "24-Oct-17", "25-Oct-17", "26-Oct-17", "27-Oct-17", "28-Oct-17", "29-Oct-17", "30-Oct-17", "31-Oct-17", "01-Nov-17", "02-Nov-17", "03-Nov-17", "04-Nov-17", "05-Nov-17", "06-Nov-17", "07-Nov-17", "08-Nov-17", "09-Nov-17", "10-Nov-17", "11-Nov-17", "12-Nov-17", "13-Nov-17", "14-Nov-17", "15-Nov-17" ], "values": [ '0', '0', 149, 141, '0', '0', '0', '0', '0', '0', 139, 1177, 477, '0', '0', 2578, '0', '0', 349, '0', '0', '0', 2195, 1057, 807, '0', '0', '0', 148, 241, '0' ] } ] slide.addChart( pptx.charts.LINE, chartData) pptx.save();

Thanks for opening this issue @andrei-cs, and thanks to @hilnius for the contribution.

The Issue is now fixed in the current codebase:

var pptx = new PptxGenJS();
var slide = pptx.addNewSlide();

var chartData = [{
  "name": "Chart",
  "labels": [ "16-Oct-17", "17-Oct-17", "18-Oct-17", "19-Oct-17", "20-Oct-17", "21-Oct-17", "22-Oct-17", "23-Oct-17", "24-Oct-17", "25-Oct-17", "26-Oct-17", "27-Oct-17", "28-Oct-17", "29-Oct-17", "30-Oct-17", "31-Oct-17", "01-Nov-17", "02-Nov-17", "03-Nov-17", "04-Nov-17", "05-Nov-17", "06-Nov-17", "07-Nov-17", "08-Nov-17", "09-Nov-17", "10-Nov-17", "11-Nov-17", "12-Nov-17", "13-Nov-17", "14-Nov-17", "15-Nov-17" ],
  "values": [ 0, 0, 149, 141, 0, 0, 0, 0, 0, 0, 139, 1177, 477, 0, 0, 2578, 0, 0, 349, 0, 0, 0, 2195, 1057, 807, 0, 0, 0, 148, 241, 0 ]
}];

slide.addChart( pptx.charts.LINE, chartData);
pptx.save();
