Formatting the chart control

[Vb2010 Beginner]

Hey,

The chart control is doing whatever it likes, and I'm looking for a way to control how it outputs axes values and how to set a specific scale. This is my current problem.

The scale on the X axis is decreasing, by default.
I also would like to limit the labels to 1 decimal place.



Cheers

Controlling Scaling




Hope that helps. You'd most likely benefit by downloading the charting samples provided by Microsoft where they give tons of examples of doing various things.

Thanks for your detailed and helpful reply, and I'm sorry for my extremely late one. For some reason it doesn't seem to be as simple a fix as above, the Y axis obeys:

 Chart1.ChartAreas(0).AxisY.LabelStyle.Format = "N1"

However for the X axis it is ineffective.I don't think it is being overwritten at another point, because this is all the code I have relating to the chart:

 Dim series_1 As New Series
        series_1.ChartType = SeriesChartType.Spline
        series_1.XValueMember = ("X values")
        series_1.YValueMembers = ("Y values")

        Chart1.Series.Add(series_1)
        Chart1.DataSource = ARpassover_table


        Chart1.ChartAreas(0).AxisX.LabelStyle.Format = "N1"

Also, changing the interval values didn't help with the scale either, it just removed the intervals in most cases, the shape of the graph never changed. I think it is because the data is bottom heavy, there are more values in the 2nd half of the data than the first. I think the chart is trying to compensate by making the intervals smaller by default, but whenever I change the intervals it just removes them. Any more ideas?

With this code :

  With Chart1.ChartAreas(0)
            .AxisX.Minimum = 0
            .AxisX.Maximum = 32
            .AxisY.Minimum = 0
            .AxisY.Maximum = 40
            ' .AxisX.Interval = 1
            .AxisX.Title = "X-Distance (m)"
            .AxisY.Title = "Y-Distance (m)"
            .AxisY.LabelStyle.Format = "N1"
            .AxisX.LabelStyle.Format = "N1"
        End With

it returns this :


Now why does it make the Y axis go up to 40, whilst limiting the X axis to 32 points of data! I thought it would make both go to the specified value. Is there some major difference in the way it handles X and Y axis formatting?

Progress! - Looping through to add the data allows me to show you how it should look, anyone know of a way to still have it bound to a datatable and recreate these results?

[Vb2010 Beginner]

Using

   For Each row As DataRow In ARpassover_table.Rows
            Chart1.Series(0).Points.AddXY(row.Item(0), row.Item(1))

        Next row

puts me back at square one. And yes, I am talking to myself, it helps :P

Is there a way to disable the automatic stuff when databinding stuff to charts?

My question is how can I format a bar chart. The color of the bar is blue. Can I use a different color for each bar? How?

[Vb2010 Beginner]

I think that's just the default image for charts, but you should really create a new thread for this, good luck.

I will use this thread. If no one answers then I will open a new one.

I've found in other forum that answers:
Chart1.Series(0).Points(1).Color = Color.Beige
