Print the graphs with additional custom text

[Leïla Benakezouh]

Hi,
1/ I need to print the graphics with additional titles and text that explain it.
How can I add this text to the PrintDocument before it is displayed on the PrintPreview Dialog or sent the printer ?
2/ I already have a routine that creates a PrintDocument with the appropriate titles and custom text and that add an image....How can I extract an image of my Syncfusion graph in order to add it to the print document ?
Thank you

Hi Leila,

Thank you for your interest in Syncfusion products.

1.How can I add this text to the PrintDocument before it is displayed on the PrintPreview Dialog or sent the printer ?

If your intension is to add title and text to chart control, you can refer the following online documentation link mentioned below,

http://help.syncfusion.com/ug_84/User%20Interface/Windows%20Forms/Chart/Documents/multiplecharttitles1.htm

http://help.syncfusion.com/ug_84/User%20Interface/Windows%20Forms/Chart/Documents/custompoints1.htm

If we add the title and text to the chart control, you will be able to print the chart with multiple title and text.

Or, If your intension is to add title and text to PrintDocument, kindly refer to the below code snippet to achieve this,

[VB]

PrintPreviewButton_click Event:

For Each lControl As Control In chartControl1.Controls
If TypeOf (lControl) Is ChartTitle Then
title.Text = "Custom Chart Title" ‘Add title to chart
chartControl1.Titles.Add(title)
End If
Dim lPageSetupDialog1 As New System.Windows.Forms.PageSetupDialog
chartControl1.PrintDocument.PrinterSettings = New Printing.PrinterSettings
lPageSetupDialog1.Document = chartControl1.PrintDocument


2. How can I extract an image of my Syncfusion graph in order to add it to the print document ?

You can use “SaveImage” property of chart to extract the chart image and add it to the print document. kindly refer to the below code snippet to achieve this,

[VB]

Me.chartControl1.SaveImage("chart.jpg")

You can refer the following online documentation link mentioned below,

Hi,
Thank you for your answer.
Maybe I didn't explain my case very well. What I need to do in to encapsulate my graph in a kind of report (by adding a specific title and an explanation of the graphic) when I print it.I don't want to add this custom text on the Graph directly.

In order to achieve that, I will need to manipulate the PrintDocument.PrintPage event and to add the title then the graph and also the text bellow the graph (see the picture attached to the message/The left picture is the expected result).
I'm already able to add the title and the text bellow the graph but my Sycfusion graph is automatically added to the PrintDocument and it fills all the space whereas I want it to occupy a speficic size (see the picture attached to the message/The right picture is the current result).
How can I control the size and location of the graph on the PrintDocument ?

Hi Leila,

Thanks for update the screen shot.

For this issue, we suggest you to extract the chart control as image and then set the size and print document location of the chart image and add it to the print document in the order(your routine). You do not print the chart control directly in print document.

You can use “SaveImage” property of chart to extract the chart image and add it to the print document. kindly refer to the below code snippet to achieve this,

[VB]

Me.chartControl1.SaveImage("chart.jpg")

You can refer the following online documentation link mentioned below,

Thanks for using Syncfusion products.

Hi,

I already thought about this solution that works well but what I don't want to do is to generate a picture and to save it on the disk (on some computers, you can not be allowed to write on the disk)every time the user needs to print a graphic.

Do you really think it is the only solution ?

Thank you.

Hi Leila,

Thanks for the update.

For this issue, the chart control needs to be saved and then added to the print document. If we save the chart by stream object, we can resolve your issue. But currently, we do not provide support to save the chart image in stream obj. This has been confirmed as a Feature Request.

We will implement this feature in our forthcoming new version releases or service pack releases. The feature implementation
would also greatly depend on the factors such as product design, code compatibility and complexity.
We will get back to you once the feature is implemented.

Could you please open the new incident in Direct-Trac for better follow-up this feature?

Thank you for your interest in Syncfusion products.
