Getting an imageMap using IGS

Using report GRAPHICS_IGS_CHART_TEST, I have managed to create some code that returns an image of a chart. This is wonderful. I also see an example where I can set a hotspot on the title so that when the user clicks on that hotspot it will launch a URL. This seems pretty straight forward. The code is as follows:

  lv_line-groupid = 'Polymers'.
  lv_line-x = 'Apr'.
*  lv_line-color = 54.
  lv_line-y = '20`'.
*      lv_line-datalabel = '2 Mil'.
  lv_line-extension = 'href=""'.
  append lv_line to xyt_data.

  lv_line-groupid = 'Refinery'.
  lv_line-x = 'Apr'.
* lv_line-color = 54.
  lv_line-y = 10.
*     lv_line-datalabel = '1 Mil'.
  lv_line-extension = 'href=""'.
  append lv_line to xyt_data.

data: ext_line        type igs_ext,
      extension       type igs_ext_tab.

* set some extensions
  ext_line-token = 'TITLE'.
  ext_line-value = 'href=""'.
  append ext_line to extension.

* create chart object
  create object igs_chart.

* set chart type
  igs_chart->type = cl_igs_chart=>co_type_area_stacked_3d.
  igs_chart->data = xyt_data.
  igs_chart->title = 'My Title'.
  igs_chart->extension = extension.

  data : lt_mime            type w3mimetabtype,
         lv_content_type    type w3param-cont_type,
         lv_content_length type i.

  call method igs_chart->send
      content_type            = lv_content_type
      content_length          = lv_content_length
      content                 = lt_mime
      imagemap                = yt_imagemap
      rfc_communication_error = 1
      rfc_system_error        = 2
      internal_error          = 3
      others                  = 4.

However, what I want to achieve is a little different. My chart is being display in HTML via IE. I want to create an imageMap so that when the user clicks on one of the columns of the chart, it will load the appropriate URL. However, I am unsure how to specify this. Is there a way to get the imageMap parameter to contain hotspots for each of the columns?

An example would be greatly appreciated.

Hi Alon,

when you look at the report you refer to (GRAPHICS_IGSCHART_TEST) you will see that somewhen the call igs_chart->execute is done returning the image map in a table structure. Looping over this table you will get the desired information.

If you have not yet started I would recommend to base on the XMLCHART interpreter where you find an example in report GRAPHICS_IGS_CE_TEST. In that report you also see how the imagemap is retrieved.

Best regards
