Problem with CL_GUI_CHART_ENGINE

Former Member — Wed, 04 Aug 2010 11:43:00 GMT

Hi,

I have a dynpro with a custom control, I create an obj from cl_gui_chart_engine. I create some demo data, convert it to XML with CALL TRANSFORMATION. Call the method u201Eset_datau201C. Set Customizing, like barchart or lines and call method u201Eset_customizingu201C.

Then the user will add more data (a second line) into the chart, so I change customizing (u201Eset_customizingu201C ) from barchart to lines and use again set_data with both data. So I wanted to display two lines in 1 chart but only the customizing ist the new one (lines) and not the data so only one line is shown.

In short: I would like to have two lines in one chart.

Can someone help?

Best regards and thanks in advance,

B.Lindackers.

I just forgot to "Clear: workarea".

Follow these steps: http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/13313. [original link is broken] Use the same object and call again set_data and you´ll see two series.

I´ve got a new problem: I want to create a chart with chart type "TimeScatter", but I don´t know how to generate the "data xml".

More informations:

I want to display this graph:
