How to specify fixed width to chart bars?

I'm using Visual Studio 2015, working with WinForms.

I link 2 images to make you guys easier to understand what I want to do:

Example 1

Example 2

In the example 1 we have 10 values with an automatic width, this is the size I want always for bars, but this is a dynamic chart so when there are less than 10 values it just fills to graph as you can see in example 2. I want the same size always, the size of the example 1, have tried to specify using:

chrt_ventesArticles.Series[Conversion.Texto(f_cursor.Campo(1))]["PixelPointWidth"] = "100";

And tried too:

chrt_ventesArticles.Series[Conversion.Texto(f_cursor.Campo(1))]["PixelPointWidth"] = Conversion.Texto(Math.Round(chrt_ventesArticles.ChartAreas[0].InnerPlotPosition.Height, 0));

But it isn't working as it should, depending on the number of values it haves a different size.

Any ideas about how to do it?

To space the bars evenly over a fixed number of slots you need to set the Minimum and Maximum values to display on an Axis.

Here you have a Bar chart and want to display the bars in a 10 slots.

So you write maybe:

yourCharArea.AxisX.Minimum = 0;
yourCharArea.AxisX.Maximum = 10;

Now you get both:

  • Always the same width of the Bars, even while some DataPoints are missing.
  • But also still the automatic scaling when you resize the Chart itself.

The latter will not work when you set the with of the Bars in pixels..!
