With Spire.Doc, we can copy the content from one word document to another word document in C#. When we need to generate a large amount of documents from a single document, clone the document will be much easier. The clone method speeds up the generation of the word documents and developers only need one single line of code to get the copy of the word document.
Now we will show the code snippet of how to clone a word document in C#.
Step 1: Create a new instance of Document and load the document from file.
Document doc = new Document();
doc.LoadFromFile("Sample.docx",FileFormat.Docx2010);
Step 2: Clone the word document.
doc.Clone();
Step 3: Save the document to file.
doc.SaveToFile("Cloneword.docx", FileFormat.Docx2010);
Effective screenshot of clone the word document:
Full codes of clone a word document:
using Spire.Doc;
namespace CloneWord
{
class Program
{
static void Main(string[] args)
{
Document doc = new Document();
doc.LoadFromFile("Sample.docx", FileFormat.Docx2010);
doc.Clone();
doc.SaveToFile("Cloneword.docx", FileFormat.Docx2010);
}
}
}
When creating chart, the legend appears by default. If we just need the chart series rather than the legend, we can delete the legend entries after creating the chart. Spire.Presentation supports to delete legend entries from chart by using ChartLegend.DeleteEntry method. This article is going to demonstrate how we can use Spire.Presentation to accomplish this function.
Below screenshot shows the example PowerPoint file which contains 3 chart legend entries:
Detail steps:
Step 1: Initialize an object of Presentation class and load the PowerPoint file.
Presentation ppt = new Presentation();
ppt.LoadFromFile("Input.pptx");
Step 2: Get the chart.
IChart chart = ppt.Slides[0].Shapes[0] as IChart;
Step 3: Delete the first and the second legend entries from the chart.
chart.ChartLegend.DeleteEntry(0); chart.ChartLegend.DeleteEntry(1);
Step 4: Save the file.
ppt.SaveToFile("Output.pptx", FileFormat.Pptx2010);
Screenshot:
Full code:
using Spire.Presentation;
using Spire.Presentation.Charts;
namespace Delete_chart_legend_entries_in_PPT
{
class Program
{
static void Main(string[] args)
{
Presentation ppt = new Presentation();
ppt.LoadFromFile("Input.pptx");
IChart chart = ppt.Slides[0].Shapes[0] as IChart;
chart.ChartLegend.DeleteEntry(0);
chart.ChartLegend.DeleteEntry(1);
ppt.SaveToFile("Output.pptx", FileFormat.Pptx2010);
}
}
}
Group Two-Level Axis Labels in a Chart in PowerPoint in C#, VB.NET
2018-03-07 06:41:56 Written by KoohjiSometimes, you may have a chart that contains two levels of horizontal axis labels, as shown in the following screenshot, and you need to group the labels by fruit and vegies. This article will show you how to group the category axis labels using Spire.Presentation.
Step 1: Create a Presentation instance and load the sample PowerPoint file.
Presentation ppt = new Presentation();
ppt.LoadFromFile("chart.pptx");
Step 2: Get the chart.
IChart chart = ppt.Slides[0].Shapes[0] as IChart;
Step 3: Get the category axis from the chart.
IChartAxis chartAxis = chart.PrimaryCategoryAxis;
Step 4: Determine if the axis has multilevel labels, if yes, group the axis labels that have the same first-level label.
if(chartAxis.HasMultiLvlLbl)
{
chartAxis.IsMergeSameLabel = true;
}
Step 5: Save the file.
ppt.SaveToFile("result.pptx", FileFormat.Pptx2010);
Output:
Full Code:
using Spire.Presentation;
using Spire.Presentation.Charts;
namespace GroupLabel
{
class Program
{
static void Main(string[] args)
{
Presentation ppt = new Presentation();
ppt.LoadFromFile("chart.pptx");
IChart chart = ppt.Slides[0].Shapes[0] as IChart;
IChartAxis chartAxis = chart.PrimaryCategoryAxis;
if (chartAxis.HasMultiLvlLbl)
{
//group labels
chartAxis.IsMergeSameLabel = true;
}
ppt.SaveToFile("result.pptx", FileFormat.Pptx2010);
}
}
}
Imports Spire.Presentation
Imports Spire.Presentation.Charts
Namespace GroupLabel
Class Program
Private Shared Sub Main(args As String())
Dim ppt As New Presentation()
ppt.LoadFromFile("chart.pptx")
Dim chart As IChart = TryCast(ppt.Slides(0).Shapes(0), IChart)
Dim chartAxis As IChartAxis = chart.PrimaryCategoryAxis
If chartAxis.HasMultiLvlLbl Then
'group labels
chartAxis.IsMergeSameLabel = True
End If
ppt.SaveToFile("result.pptx", FileFormat.Pptx2010)
End Sub
End Class
End Namespace
