Re: Embedded Excel in powerpoint for a chart

hi, can you help me?

I need modify the embed chart. in  "ppt/charts/chart1.xml". what do you do to fixed?

Demo runs ok, but when I need Edit data in the chart over demo.pptx it is missing.

my code is the sample in demo.
// Merge a chart
$ChartRef = 'my_chart'; // Title of the shape that embeds the chart
$SeriesNameOrNum = 1;
$NewValues = array( array('Cat. A','Cat. B','Cat. C','Cat. D'), array(0.7, 1.0, 3.2, 42.8) );
$NewLegend = "Merged";
$TBS->PlugIn(OPENTBS_CHART, $ChartRef, $SeriesNameOrNum, $NewValues, $NewLegend);


thanks for all you cooperation.

The data is not missing in the template, but it is missing in the result of the merge.
This is because Powerpoint stores a copy of the chart's data in an Excel sub-file embedded in the PPTX (the Excel that appears when you edit data in the chart of the PPTX).
But OpenTBS cannot edit this Excel sub-file. Since is becomes inconsistent with the modified chart, then OpenTBS delete the Excel sub-file.

thanks a lot.
