# Linear graph in Excel

I want to create a linear graph in Excel 2010 using the data in the image attached.
The problem is when I select the rows and columns and then try to create a graph, it starts plotting from n=1.
Please let me know how I can start plotting from 0.

If possible ,please give me the step by step procedure.

Thanks!

Hello,

the X axis shows the category labels. Since your data does not include any categories for the four data points for each line, Excel defaults to numbering them from 1 to 4.

What would you like to see on the X axis instead? Insert a row above your data table, enter your categories in that row, then select the data including the category row and build a new line chart.

See the result of that attached.

I think I may have misread your question. You want the row starting with N as your category labels.

Remove the n in the cell, then select the table. If the top left cell of the selection is empty, Excel will use the first row as the category labels. Afterwards, you can put the N back.

I actually dont want any category labels. Can I just show show it for a uniform distribution between 0 and 200? I want the default numbering to start from 0.
The X-axis must have only "0", "1", "3", and "200" marked.
Thanks!

Please let me know if it possible to have the data points on X axis (0 to 200) uniformly distributes)

If you want to fix the existing chart, right click the chart and select "Select Data".

Delete the "n" series.
Click the Edit button in the right hand pane for Horizontal (Category) labels.
Select the four cells from one cell to the right of the "n" cell to the end. (Sorry, from your screenshot it is not apparent what the cell addresses are. If "n" is in A1, select B1 to E1. Adjust to your setting)

Click OK on all dialog boxes.

Yes, you can do that with an XY chart instead of a line chart.

Right click the chart, select "Change Chart Type" and select the XY (Scatter) chart type with the lines and the markers.
