Hi Fathimath,

Thank you for contacting Syncfusion support.

At present we do not have support to draw chart directly in PDF. However we can draw the chart as images in PDF document. Please refer the below code snippet for more details,

//Create PDF document

PdfDocument doc = new PdfDocument();

//Add a page to the document

PdfPage page = doc.Pages.Add();

//Create PDF graphics for the page

PdfGraphics graphics = page.Graphics;

//Load the image from the disk

FileStream imageStream = new FileStream("pie_chart.png", FileMode.Open, FileAccess.Read);

PdfBitmap image = new PdfBitmap(imageStream);

//Draw the image

graphics.DrawImage(image, 0, 0, page.GetClientSize().Width, page.GetClientSize().Height);

//Saving the PDF to the MemoryStream

MemoryStream stream = new MemoryStream();

doc.Save(stream);

Regarding Chart to PDF:

We can export the pie chart to pdf using the export method in export module. Based on that we have prepared a sample for your reference. Please find the below sample and code snippet.

Code Snippet:

<ejs-accumulationchart id="container" title="Mobile Browser Statistics" load="load"enableAnimation="false">

<e-accumulationchart-center x="50%" y="50%"></e-accumulationchart-center>

<e-accumulationchart-tooltipsettings enable="true"></e-accumulationchart-tooltipsettings>

<e-accumulationchart-legendsettings visible="false">

</e-accumulationchart-legendsettings>

<e-accumulation-series-collection>

<e-accumulation-series dataSource="ViewBag.dataSource" xName="xValue"yName="yValue" name="Browser" explodeIndex="0" explode="true"explodeOffset="10%">

<e-accumulationseries-datalabel name="text" visible="true">

<e-font fontWeight="600" color="white"></e-font>

</e-accumulationseries-datalabel>

</e-accumulation-series>

</e-accumulation-series-collection>

</ejs-accumulationchart>

<div>

<ejs-button id="button" content="Export" iconCss="e-icons e-play-icon" cssClass="e-flat" isPrimary="true"></ejs-button>

</div>

document.getElementById('button').onclick = () => {

var chart = document.getElementById('container').ej2_instances[0];

chart.exportModule.export('PDF', 'chart', 'Landscape', [chart] null, 1600);

};

</script>
