Incorrect values when reading line chart from workbook

Hi,

When reading information about data series from a line chart embedded within a worksheet, Aspose.Cells.Charts.Series.DisplayName and Aspose.Cells.Charts.Series.Area.ForegroundColor are not correct.

For example, when the following code is used to read the attached workbook

static void Main(string[] args)
{
Workbook wkbk = new Workbook(@“test.xlsx”);

foreach (Worksheet wks in wkbk.Worksheets)
{
foreach (Chart chart in wks.Charts)
{
chart.Calculate();
chart.RefreshPivotData();

Console.WriteLine("Chart Name: " + chart.Name);

SeriesCollection dataSource = chart.NSeries;
foreach (Series series in dataSource)
{
Console.WriteLine("Series DisplayName: " + series.DisplayName);
Console.WriteLine("Series Name: " + series.Name);
Console.WriteLine("Series ForegroundColor: " + series.Area.ForegroundColor.ToString());
Console.WriteLine("Series Values: " + series.Values);
}
Console.WriteLine();
}
}
}

The resulting output is:

Chart Name: Line Chart
Series DisplayName: Two
Series Name: =Sheet1!$B$1
Series ForegroundColor: Color [A=0, R=155, G=187, B=89]
Series Values: =Sheet1!$B$2:$B$32
Series DisplayName: Three
Series Name: =Sheet1!$C$1
Series ForegroundColor: Color [A=0, R=128, G=100, B=162]
Series Values: =Sheet1!$C$2:$C$32
Series DisplayName:
Series Name: =Sheet1!$D$1
Series ForegroundColor: Color [Empty]
Series Values: =Sheet1!$D$2:$D$32

Chart Name: Bar Chart
Series DisplayName: Day
Series Name: =Sheet1!$A$1
Series ForegroundColor: Color [A=0, R=0, G=255, B=0]
Series Values: =Sheet1!$A$2:$A$32
Series DisplayName: One
Series Name: =Sheet1!$B$1
Series ForegroundColor: Color [A=0, R=255, G=0, B=0]
Series Values: =Sheet1!$B$2:$B$32

Chart Name: Column Chart
Series DisplayName: One
Series Name: =Sheet1!$B$1
Series ForegroundColor: Color [A=0, R=0, G=0, B=255]
Series Values: =Sheet1!$B$2:$B$32
Series DisplayName: Two
Series Name: =Sheet1!$C$1
Series ForegroundColor: Color [A=0, R=255, G=0, B=0]
Series Values: =Sheet1!$C$2:$C$32
Series DisplayName: Three
Series Name: =Sheet1!$D$1
Series ForegroundColor: Color [A=0, R=0, G=255, B=0]
Series Values: =Sheet1!$D$2:$D$32

The values highlighted in red do not seem to be correct when compared with what’s in the line chart in the workbook. In comparison, the corresponding values for the bar chart and the column chart look correct.

Can you please investigate? Thanks.

Hi,

Please download and try the latest fix: Aspose.Cells for .NET v8.1.2.3.

If the type is line, please use Line.Color property.

Please see the following
code:

C#
foreach (Worksheet wks in
workbook.Worksheets)
{
foreach (Chart chart in
wks.Charts)
{

chart.Calculate();

chart.RefreshPivotData();

Console.WriteLine("Chart
Name: " + chart.Name);

SeriesCollection dataSource =
chart.NSeries;
foreach (Series series in
dataSource)
{

Console.WriteLine("Series DisplayName: " +
series.DisplayName);
Console.WriteLine("Series Name:
" + series.Name);
Console.WriteLine("Series border
ForegroundColor: " + series.Border.Color.ToString());

Console.WriteLine("Series ForegroundColor: " +
series.Area.ForegroundColor.ToString());

Console.WriteLine("Series Values: " + series.Values);

}
Console.WriteLine();

}
}

Just confirming that the problem has been fixed.
