Question

I have the following function doing what I want it to do, except that instead of generating the chart on a new worksheet I would like to embed it in the worksheet where the data is written. Also, how can I remove the legend? Here is what I’ve got:

def Get_IV_Data(current_file):

    xlApp = win32com.client.Dispatch('Excel.Application')
    xlApp.Visible = True

    xlBook = xlApp.Workbooks.Add()

    xlSheet = xlBook.Sheets(1)
    xlSheet.Name = filename

    for i in range(0, 10):
        fluff = current_file.readline()

    Input_Parameters = fluff.split("\t")

    from operator import itemgetter
    Cal_Std_V = float(itemgetter(2)(Input_Parameters))

    xlSheet.Cells(1,1).Value = "V"
    xlSheet.Cells(1,2).Value = "I"
    xlSheet.Cells(1,3).Value = "P"

    output_line = 2

    # Assign the data to lists

    for line in current_file:
        try:
            a = line.split("\t")
            STD1, STD2, STD3, V, I, Vcorr, Icorr, v1, v2, v3 = a
            I = round(float(I) * (Cal_Std_V / float(STD1)), 6)
            P = round(float(V) * I, 3)
            xlSheet.Cells(output_line, 1).Value = V
            xlSheet.Cells(output_line, 2).Value = I
            xlSheet.Cells(output_line, 3).Value = P
            output_line += 1

        except ValueError:
            pass

    chart = xlApp.Charts.Add()
    chart.Name= "Plot "+xlSheet.Name
    series = chart.SeriesCollection(1)
    series.XValues= xlSheet.Range("A2:A200")
    series.Values= xlSheet.Range("B2:B200")
    series.Name= filename

Answer 1

Set the location of a Chart by calling its Location method, which takes two parameters.

The first is called Where, which takes an enumeration with names xlLocationAsNewSheet, xlLocationAsObject, and xlLocationAutomatic having values of 1, 2, and 3 respectively.

The second parameter is Name, which is a worksheet name.

Here is that in Python:

xlLocation = {"AsNewSheet": 1,
              "AsObject": 2,
              "Automatic": 3 }
chart.Location(xlLocation["AsObject"], xlSheet.Name)

If you prefer magic numbers you can change that to

chart.Location(2, xlSheet.Name)
