VBA + Matlab：饼图麻烦

Question

My task is 'create pie chart in excel and then show it in matlab'.

as i think, i have two troubles:

1) is this chart correctly create chart? (A1-A6 are names, B1-B6 - numbers).

Ok, this function work.

Function CreateChart() As Excel.Chart
Dim title As String
title = "One"


Dim Book As Workbook
Set Book = ThisWorkbook

Dim new_sheet As Excel.Worksheet
Set new_sheet = Book.Sheets(1)

Dim new_chart As Excel.Chart
Set new_chart = Charts.Add()

ActiveChart.ChartType = xlPie

ActiveChart.SetSourceData Source:=new_sheet.Range("A1:B6"), _
      PlotBy:=xlColumns

ActiveChart.Location Where:=xlLocationAutomatic, Name:=title

With ActiveChart
    .HasTitle = True
    .ChartTitle.Characters.Text = title
End With

Set CreateChart = new_chart
End Function

2) How to interact with this procedure ( in future - function , returning Chart )

using matlab and draw this pie chart in matlab?

   function chart = CreateChart( DataMatrix )

   pie = actxserver('Excel.Chart');
   all_pies = actxserver('Excel.Charts');
   pietype = actxserver('Excel.XlChartType');

   pie = all_pies.Add();

   pie.ChartType = pietype.xlPie;

   % here is a trouble to put data from matrix

   pie.SetSourceData Source DataMatrix              %hm.. strange

   end

This code doesn't work! (i don't know how to rewrite string

ActiveChart.SetSourceData Source:=new_sheet.Range("A1:B6"), PloBy = xlColumns )

PS: I think it is better to load script from excel file and return Chart.

But how to work with this chart in matlab? (and draw it)

您始终可以使用xlsread将excel值加载到matlab并使用pie或pie3在matlab自身中绘制饼图。
