Code that produced the output with Labels missing

String file = getClass().getClassLoader().getResource("LinkAI_Lite_Template_latest.pptx").getFile();
pres = new Presentation(file);
ISlide slide2 = pres.getSlides().get_Item(1);
IPPImage image2xM = null;
image2xM = slide2.getPresentation().getImages().addImage(imageM);
for (IShape shp : slide2.getShapes()) {
	if (shp.getName().equalsIgnoreCase(VIDEO_TITLE_VIDEO_LENGTH)) {
		((AutoShape) shp).getTextFrame().setText(pptDataLite.getAdName() + getAdDuration(pptDataLite.getVideoLength()));
	} else if(shp.getName().equalsIgnoreCase("Chart 16")) {
		chart = (IChart) shp;
		IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();
	    fact.getCell(SHEET_1, 1,0).setValue("IMPACT");
		fact.getCell(SHEET_1, 1, 1).setValue(pptDataLite.getImpact());
		fact.getCell(SHEET_1, 1, 2).setValue(100 - pptDataLite.getImpact());
		setChartColor(shp, formatUtil(String.valueOf(pptDataLite.getImpact())), getUnderPerformingValue(percentileValues,IMPACT), getOverPerformingValue(percentileValues, IMPACT));
	} else if(shp.getName().equalsIgnoreCase("Chart 17")) {
		chart = (IChart) shp;
		IChartDataWorkbook fact = chart.getChartData().getChartDataWorkbook();
		fact.getCell(SHEET_1, 1,0).setValue("POWER");
		fact.getCell(SHEET_1, 1, 1).setValue(pptDataLite.getPower());
		fact.getCell(SHEET_1, 1, 2).setValue(100 - pptDataLite.getPower());
		setChartColor(shp, formatUtil(String.valueOf(pptDataLite.getPower())), getUnderPerformingValue(percentileValues, POWER_INDICATOR), getOverPerformingValue(percentileValues, POWER_INDICATOR));

Please let me know if you require any other info.


Your zip archive is not containing the “LinkAI_Lite_Template_latest.pptx” file and your code snippet is not compilable. Please share a comprehensive code example and the presentation file.


DigitalAI_Template.pptx in the zipped folder is the file to refer as template and DigitalAI_Test 1_6.30.2022.pptx is the resultant file with labels missing .

if you open both the files , you will clearly understand .

Related to code , the sample which I sent contains changes related to labels “IMPACT” and “POWER” which went missing after these lines .

Kindly help resolving the issue and let me know if you need any other info .


Unfortunately, I have not managed to reproduce the problem you have encountered. Please also note that the template presentation does not contain the Chart 17 on the slide 2. Please try isolating the problem and share a compilable code example that reproduces the problem.
