#289 XLSX-Charts-Chart's preview-not supported in excel

[Pradeep Nemadi]

In calc, Chart is represented by
1. content.xml,styles.xml, settings.xml : which describes the chart
2. chart preview: which is in the form of binary file under objectReplacement folder(i.e object 1, object 2, etc)

In Excel, chart is represented using chart.xml file. There is no image or binary file available for chart preview.

so while conversion from xlsx to ods, chart preview wont be retained and this will affect the display of chart .
double click on chart to view it, it will correct the display of chart.

defect"2015806-XLSX - Charts - Axxis labels too small to read" has this issue
