In many requirement graphical charts are required by the clients since a graph is much more appealing to the user. As graphs enables a better analysis of data to the user. It is however quite simple to provide the same functionality for building graphical charts in your ABAP report itself by using CL_IGS_CHART_ENGINE.

Recently I had the requirement of printing Charts on Smart forms. In Smart forms we can print the image if the image is already uploaded to the Form Graphics (SE78). I search through the SCN but doesn't find the solution of printing the charts on Smart forms. Then I had an idea of uploading the graphical image generated by CL_IGS_CHART_ENGINE dynamically to Form Graphics (SE78).  I have used the same functionality as used in Form Graphics (SE78) import to upload the image dynamically in Form Graphics.

Solution:

Create a Sample smart-Form to display the Graphical Chart generated by the custom function module.



TD_NAME is the name of the graphical chart generated dynamically by the custom function module YTESTCHART.



 

Delete the graphics after printing.


 

Print Preview of the Smart Form

Conclusion: -

Now we can print any type of charts using CL_IGS_CHART_ENGINE on smart-forms dynamically. we just need to change the XML for changing the chart.

I hope that makes drawing graphs/charts with ABAP complete and easily achievable.

Thanks for reading this blog post. I would like to see your comments and would like to answer questions which u can post at Q&A tag area: https://answers.sap.com/tags/66233466-fcd6-45d2-a9ae-2cba38c72e19
