Setting X-Axis labels with a ChartSpace

I'm using an OWC11 ChartSpace object on a userform. It contains 1 chart and the x-axis is a set of dates to correspond to the y-values. The ChartType is a LineType.

How do I set the X-axis labels to my dates using VBA? I'm using Office 2003.

start recording a macro and do it manually.
then look at the code and modify it to suit

there is no vba code to set the axis and cart labels dynamically

Do you have a spreadsheet control that you are using for the data or is the whole thing populated in code?

rorya - the entire thing is programmed from VBA. I'm not using Excel at all.

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Werafa - I had tried that, but the methods that a recorded macro picks up do not all exist in the OWC11 object. And specifically, the methods around setting the x-axis.

If vba doesn't let you change the axes, can anyone recommend a third party object that does allow me more control over graphing? Cheap is good, free is better :-)

You don't actually need to be in Excel to use a spreadsheet control! :)
I should be back in the office shortly - I'll check my OWC code samples - I'm pretty sure it is possible to do what you want. Do you have the dates in an array already?

Rorya - thanks for that, I appreciate the help. I have 2 arrays that I read from a database. One contains the dates for the x-axis and the other contains the y-values.

Assuming your chart variable is called cht and your date array is adteCategories, the code would be:

cht.SetData chDimCategories, chDataLiteral, adteCategories


I assume you know you could bind the chart to the database?

Rorya - I can't get this to work. Do you have a code sample that you could post?

I don't want to bind to a database as there is some manipulation of the data before displaying.

Sure - here's a rough sample:

Dim ser As ChSeries
    Dim cht As ChChart
    Dim objAxis As ChAxis
    ' note the data and category arrays must be of Variant type
    Dim varDataCats(1 To 50), varDataVals(1 To 50)
    Dim n As Long
    
    For n = 1 To 50
        varDataCats(n) = DateSerial(2010, 1, n)
        varDataVals(n) = n
    Next n
    
    With Me.ChartSpace1
        Debug.Print .Charts.Count
        .Charts.Add
        Set cht = .Charts(0)
    End With
    
    With cht
        .Type = chChartTypeLineMarkers
        .SeriesCollection.Add
        .SetData chDimCategories, chDataLiteral, varDataCats
        .SeriesCollection(0).SetData chDimValues, chDataLiteral, varDataVals
        .HasLegend = False
        .HasTitle = True
        Set objAxis = .Axes(0)
        With objAxis
            .Font.Size = 6
            .NumberFormat = "MM/DD/YYYY"
            ' don't want the dates grouped
            .GroupingType = chAxisGroupingNone
        End With

    End With

Thanks Rorya - my mistake was in not making the date array a variant array.
