I am attaching an Excel sheet SheetToImage5.xls. After creating the chart and setting the legend entries, whne I try to set the legend position, I get an Object refernce exception at chart.Calculate().
And If I skip this exception, Later there is another Exception when I do a sheetToImage() of the datasheet after moving the chart from the chartsheet to the datasheet SheetToImage6.xls.

Hi,
"I am attaching an Excel sheet SheetToImage5.xls. After creating the

And If I skip this exception, Later there is another Exception when

I have tested both your scenarios and found both the issues as you mentioned. We will figure it out soon.
Your issue has been logged into our internal issue tracking system with an issue id: CELLSNET-11783.
Thank you.
Hi,
Thank you for considering Aspose.
Please try the attached latest version of Aspose.Cells. If you still find any issue, please provide us the sample code and we will check it soon.
Thank You & Best Regards,
I checked the new dll. The Legend Overlap issue and the chart.Calculate issue seemed to be fixed. But I see new issues. The complete chart is not visible. Sometimes the Axis lable is cut and at other times, the Axis itslef is not visible. Moreover not all the items of the legend are visible. In the attached chart there are 10 legend items, however only 7 are visible. Please suggest.
Without the chart displaying completely with the Axis and the Axis Labels, this fix has no meaning. This is quiet urgent for us to Fix. Request you to please look into the issue ASAP and suggest.
Hi,
Well, you must set the height of plot area at the same time.
e.g.
int y = chart.Legend.Y;
int height = chart.Legend.Height;
int originalY = chart.PlotArea.Y;
chart.PlotArea.Y = y + (int)(height * 4000f / chart.ChartObject.HeightPt) + 150;
//You may set other value too
chart.PlotArea.Height -= (chart.PlotArea.Y - originalY);
Thank you.
Thanks for the suggestion. With this the chart is perfect. Just one issue still exists. The Legend does not display all the members. The attached chart has 10 legend items, however only 7 are displayed.
Hi,
The items of legend not shown fully are actually caused by the height of legend box being small.
There are two way to fix it.
1) Add the height of legend.
int y = chart.Legend.Y;
//Adds height of legend
chart.Legend.Height += chart.Legend.Height / 4;
int height = chart.Legend.Height;
int originalY = chart.PlotArea.Y;
chart.PlotArea.Y = y + (int)(height * 4000f / chart.ChartObject.HeightPt) + 150;
chart.PlotArea.Height -= (chart.PlotArea.Y - originalY);
2) Make the legend display 2 items at 1 row
int y = chart.Legend.Y;
//Adds width of legend
chart.Legend.Height -= chart.Legend.Height / 4;
chart.Legend.Width += chart.Legend.Width;
int height = chart.Legend.Height;
int originalY = chart.PlotArea.Y;
chart.PlotArea.Y = y + (int)(height * 4000f / chart.ChartObject.HeightPt) + 150;
chart.PlotArea.Height -= (chart.PlotArea.Y - originalY);
Thank you.
