(Solved) – VBA x-axis dynamic range

(solved)-–-vba-x-axis-dynamic-range

I’m trying to set the max x value on an XYScatter chart to the series-defined name.

I generated a chart then added data to cells A7, B7, and C7 (shown below).

The max x value jumped from 5 to 8 and the major unit changed from 1 to 2. I want the max x value to be equal to the max value in column A and for the x axis to automatically update as data are entered (e.g. if I continued to add data up until cells A11, B11, and C11, the x axis would show 10).

I’d also like the major scale on the x axis to stay at 1 until 12 is on the x-axis).

ch.Chart.Axes(xlCategory).MaximumScale = WorksheetFunction.Max(Columns(1)) sets the max when the chart is generated but does not update when the max value is changed.

enter image description here

Any thoughts on how to accomplish this?

wsData.Names.Add Name:="Session", RefersToR1C1:="=OFFSET(Sheet1!R2C1,0,0,COUNTA(Sheet1!C1)-1)"
wsData.Names.Add Name:="Measure1", RefersToR1C1:="=OFFSET(Sheet1!R2C2,0,0,COUNTA(Sheet1!C2)-1)"
wsData.Names.Add Name:="Measure2", RefersToR1C1:="=OFFSET(Sheet1!R2C3,0,0,COUNTA(Sheet1!C3)-1)"
