Hello,

Thanks for your inquiry.
Sorry that our Spire.Presentation doesn't support the setting of line color and width for PrimaryValueAxis at present. We will consider adding it in our future upgrade. Once there's an update, I will let you know.

Sincerely,
Jane

Hello Stecya,

Glad to inform that your issue has been resolved. Please download the Spire.Presentation Pack Version:2.9 and use the below code to set the axis color and width.

Code: Select all
IChart chart = presentation.Slides[0].Shapes[0] as IChart;
//SecondaryValueAxis is for Y axis and  PrimaryValueAxis is for X axixs.
chart.SecondaryValueAxis.ChartEffectFormat.Line.FillType = FillFormatType.Solid;
chart.SecondaryValueAxis.ChartEffectFormat.Line.Width = 2;
chart.SecondaryValueAxis.ChartEffectFormat.Line.FillFormat.SolidFillColor.Color = Color.Red;

Hello,
When i get a chart in a slide it doesn't get the color and labels.
- Chart line color turns green to red
- Chart labels turns to string empty.

I'm giving the sample code and sample presentation file below.

Chart on template slide
18f44514-ccfb-4579-84f6-533aaa383b6e.png


Chart on output slide
817efdf2-99fb-49f7-9bd6-fc127eac0693.png


Sample Code:

Code: Select all
IChart chart = templatePresentation.Slides[0].Shapes.ToArray().FirstOrDefault(x => x.Name == "Chart 23") as IChart;
//SecondaryValueAxis is for Y axis and  PrimaryValueAxis is for X axixs.
var chartFillType = chart.PrimaryCategoryAxis.ChartEffectFormat.Line.FillType;
var chartWidth = chart.PrimaryCategoryAxis.ChartEffectFormat.Line.Width;
var chartLineColor = chart.PrimaryCategoryAxis.ChartEffectFormat.Line.FillFormat.SolidFillColor.Color;

Debug.WriteLine("chartFillType-PrimaryCategoryAxis:" + chartFillType);
Debug.WriteLine("chartWidth-PrimaryCategoryAxis:" + chartWidth);
Debug.WriteLine("chartLineColor-PrimaryCategoryAxis:" + chartLineColor);


Output:
chartFillType:UnDefined
chartWidth:NaN
chartLineColor:Color [A=255, R=0, G=0, B=0]

Hello Omur,

Thanks for your feedback.
After I tried to load your source .pptx file(example_template2.pptx) and saved it to a new .pptx file, the chart color still is green that is same as the original.
Code: Select all
 Presentation templatePresentation = new Presentation();
 templatePresentation.LoadFromFile("example_template2.pptx");
 templatePresentation.SaveToFile("result.pptx",FileFormat.Pptx2013);

The above is my test code. If you tested differently than I do, please share your full code to help me reproduce your color issue. Thank you!

For the issue about the data read from the axis lines, the result you got is correct. In your template file, the attributes of the axis lines are not defined(as shown below).
original.png

After defining the axis lines like the below, you can retrieve these values.

If you have any questions, please contact us.

Thank you for your reply. At my code i'm changing the template slide chart data and append that slide into new presentation file.

Template file :
example_template2.rar

Result File :
result.rar


My FullCode is:

Code: Select all
using Newtonsoft.Json.Linq;
using Spire.Presentation;
using Spire.Presentation.Charts;
using System;
using System.Linq;

namespace PptxTester
{
    class Program
    {
        static void Main(string[] args)
        {
            //Load template presentation
            Presentation templatePresentation = new Presentation();
            templatePresentation.LoadFromFile("example_template2.pptx");
           

            //Create new presentation
            Spire.Presentation.Presentation newPresentation = new Spire.Presentation.Presentation();
            newPresentation.Slides.RemoveAt(0);

            //Get first slide from template presentation
            var slide = templatePresentation.Slides[0];

            //Change Chart Data                       
            IChart chart = slide.Shapes.ToArray().FirstOrDefault(x => x.Name == "Chart 23") as IChart;
            chart.ChartData[0, 1].Value = "Series 1";
            chart.ChartData[1, 0].Value = "Male";
            chart.ChartData[2, 0].Value = "Female";
            chart.ChartData[1, 1].Value = 0.1;
            chart.ChartData[2, 1].Value = 0.9;

            int categoryCount = 2;
            int seriesCount = 1;
            chart.Series.SeriesLabel = chart.ChartData["B1", GetColumnName(seriesCount) + "1"];

            for (int i = 0; i < seriesCount; i++)
            {
                string letter = GetColumnName(i + 1);
                chart.Series[i].Values = chart.ChartData[letter + "2", letter + (categoryCount + 1)];
            }
            //------------------------------------------------------------------------------------------

            //Append first slide to new presentation
            newPresentation.Slides.Append(slide);

            //Save presentation
            newPresentation.SaveToFile("result.pptx", FileFormat.Pptx2013);
        }

        static string GetColumnName(int index)
        {
            const string letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

            var value = "";

            if (index >= letters.Length)
                value += letters[index / letters.Length - 1];

            value += letters[index % letters.Length];

            return value;
        }
    }
}

Hello Omur,

Thanks for providing your code and files. I have reproduced the color issue and logged it into our issue tracking system with the ticket SPIREPPT-1694.
We will notify you once it is resolved.

Feel free to contact us if any questions.

Hello Omur,

I have got news about the color issue from our Dev team. When resetting this property chart.Series.SeriesLabel like chart.Series.SeriesLabel=chart.ChartData["B1", GetColumnName(seriesCount) + "1"]; in your code, the format of the series is initialized, so please reset the fill format for series after this line "chart.Series.SeriesLabel=chart.ChartData["B1", GetColumnName(seriesCount) + "1"];"

Sample code for reference:
Code: Select all
       
            IChart chart = slide.Shapes.ToArray().FirstOrDefault(x => x.Name == "Chart 23") as IChart;
              //Get original fill format of series
            List<FillFormat> fillFormat = new List<FillFormat>();
            for (int j = 0; j < chart.Series.Count; j++)
            {
                fillFormat.Add(chart.Series[j].Fill);
            }
           .....
           


Code: Select all
          chart.Series.SeriesLabel = chart.ChartData["B1", GetColumnName(seriesCount) + "1"];
            //Set the fill format for Series
            for (int j = 0; j < chart.Series.Count; j++)
            {
                chart.Series[j].Fill.FillType = fillFormat[j].FillType;
                chart.Series[j].Fill.SolidColor.Color = fillFormat[j].SolidColor.Color;
            }

Hello Omur,

You're welcome. Thanks for your feedback.
For the new issue about data labels, please refer to the following code snippet to add data labels for series and set their formats.
Code: Select all
        //Set the fill format for Series
            for (int j = 0; j < chart.Series.Count; j++)
            {
                chart.Series[j].Fill.FillType = fillFormat[j].FillType;
                chart.Series[j].Fill.SolidColor.Color = fillFormat[j].SolidColor.Color;
               
                //Add and set data labels
                for (int i = 0; i < 2; i++)
                {
                    ChartDataLabel dataLabel = chart.Series[j].DataLabels.Add();
                    dataLabel.HasDataSource = false;
                    dataLabel.LabelValueVisible = true;
                    dataLabel.NumberFormat = "0%";                 
                }

            }
