Hi,
I have a question about the background color, when using PdfSharp.Charting;

For now, I can create a chart.. and my background on the plotarea is oke. This is White.
chart.PlotArea.FillFormat.Color = XColors.White;

But outside the plot area ( where the labels, legend etc etc ) are, I still have the White to Blue (fading) background. How can I remove that / make it transparent??

-----------------------

Also I have another question, how to turn the X labels? Or is it possible to skip some values.

Thanks for answering!

Hi!

I have no expertise with charts ...

Re: X axis:
The XAxis property has members MinorTick and MajorTick. That should do the trick.
Not sure, but filling the XValues collection could also do the trick.

Re: Background color:
I'm afraid these colours are hard-coded in the ChartFrame class (Draw method).
Search for "XColor.FromArgb(0xFFD0DEEF)" and update the source code as needed.

Thanks!!,
Background color is fixed!
OLD:
//XLinearGradientBrush brush = new XLinearGradientBrush(chartRect, XColor.FromArgb(0xFFD0DEEF), XColors.White,
// XLinearGradientMode.Vertical);
NEW:
XLinearGradientBrush brush = new XLinearGradientBrush(chartRect, XColor.FromArgb(255,255,255), XColors.White,
XLinearGradientMode.Vertical);

THANKS!!! - OpenSource Rulesz!!
About the Xasis, I have to try ...

But, another question,..
Do you know what the difference is between PdfSharp.Charting.dll & PdfSharp.Charting-WPF.dll. What does WPF?

Thanks!

They should do the same - but using different implementations (one based on old-fashioned GDI+ code, one based on new-fandangled WPF that comes with .NET Framework 3.5).

Hi,

The ticklabels don't work for me...
I put some other data into the graph, but.. I can't remove or reshape / rotate the labels on the xasis...

This is a part of my code:
XSeries xseries = chart.XValues.AddXSeries();
xseries.Add("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N");
chart.XAxis.MajorTick = 100;
chart.XAxis.MinorTick = 10;
chart.XAxis.MajorTickMark = TickMarkType.Inside;

chart.XAxis.Title.Caption = "X-Axis";

In my original, I don't add a serie to the X-Axis.. but I'll did this because its better for seeying differences.
But there is no difference, when I uses the majorTick / minorTick.. the values are still on the same place.

What I originally want to do, is:
* No adding of manually xseries ( but take it from original )
* Skip some xvalues ( on labels only ) display 1 of 500 values
* rotate the values

And another question:
I don't know.. if the y values are around the 0.000005678 .. how to see that on the values, then I see only 0.0

Thanks for answering!

Please can you answer this question?

Thanks!

Sorry!!!, Maybe it sounds al little bit like nagging, but has someone a solution for my problem?
I am unfortunately don't know where I should look, so why ...

Thank you very much for answering.
Kind regards, Gerard Nijkamp

Try multiplying all your numbers by a million.

Thanks!, but is there no other option?

A better one?
And do you know how to skip some x-values??
Thanks for your'e answer!
