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
FUNCTION ytestchart.
