Line chart - wrong load type and changing series colors

[Archigo]

Hello

I am loading in a line chart.

When it is loaded into spire, it becomes a "ChartType.LineMarkers" where it should be "ChartType.Line".

This is simple to Work around though.

My second issue is that when I do

Code: Select all

IChart chart = presentation.Slides[0].Shapes[0] as IChart;

                for (int i = 0; i < chart.Series.Count; i++)
                {
                    chart.Series[i].Fill.FillType = FillFormatType.Solid;
                    chart.Series[i].Fill.SolidColor.Color = Color.Aqua;
                }

The colors are unchanged after saving. This same code is changing colors fine on other charts.

How do i change the colors of series in a line chart?

The attach function is not working for me, so i have uploaded my test project externally: https://ufile.io/ler44

Dear Archigo,

Thanks for your waiting.
Now the ChartType issue has been fixed in Spire.Presentation Pack Hotfix Version:2.8.10, welcome to have a test.
For the second issue, there is something wrong in your code, please change it to below code.

Code: Select all

chart.Series[i].Line.FillType = FillFormatType.Solid;
chart.Series[i].Line.SolidFillColor.Color = Color.Aqua;

Looking forward to your feedback.

The new version fixed my issue, thanks

I cannot find anywhere in the tutorial where it is showed that you need to use "chart.Series[i]. Line" instead of "chart.Series[i].Fill" which is used for all the chart types in the tutorials. This might be worth adding as a hint in the tutorial about coloring series.
