Creating a X x Y chart in Excel with C#
<p>I'm trying to create a chart in Excel with C#. What I did so far is populating an Excel spreadsheet with the data I need to plot. I Have data on my spreadsheet that looks like this:</p>

<pre><code>T    U
10  10
20  5
30  3,333333333
40  2,5
50  2
60  1,666666667
70  1,428571429
80  1,25
90  1,111111111
100 1
110 0,909090909
120 0,833333333
130 0,769230769
140 0,714285714
150 0,666666667
160 0,625
</code></pre>

<p>I have data from line 1 to line 40. 
I want to create a chart in Excel like this one:</p>

<p>Notice that on the X axis, I want to put the values (or some of the values) from column T, and in the Y axis, the values from the U column.</p>

<p>I made the following code to create a chart:</p>

<pre><code>object misValue = System.Reflection.Missing.Value;

Microsoft.Office.Interop.Excel.Application xla = new Microsoft.Office.Interop.Excel.Application();
Workbook wb = xla.Workbooks.Add(XlSheetType.xlWorksheet);
Worksheet ws = (Worksheet)xla.ActiveSheet;

Microsoft.Office.Interop.Excel.Range chartRange;
Microsoft.Office.Interop.Excel.ChartObjects xlCharts = (Microsoft.Office.Interop.Excel.ChartObjects)ws.ChartObjects(Type.Missing);
Microsoft.Office.Interop.Excel.ChartObject myChart = (Microsoft.Office.Interop.Excel.ChartObject)xlCharts.Add(240, 90, 468, 315);
Microsoft.Office.Interop.Excel.Chart chartPage = myChart.Chart;
chartRange = ws.get_Range("U1", "U40");
chartPage.SetSourceData(chartRange, misValue);
chartPage.ChartType = Microsoft.Office.Interop.Excel.XlChartType.xlLine;
</code></pre>

<p>which got me the following result:</p>

<p><img src="http://i.stack.imgur.com/raJBw.png" alt="enter image description here"></p>

<p>which is pretty close to what I need, but I couldn't set the values for the X axis.
Can someone please tell me how to assign the values from the range T1 to T40 to the X axis?
And if possible, how can I remove the label "Série 1" from the chart?</p>
