I am trying to graph some points with the following values:

x axis value 0 240 1400 1640 1880
y axis value 5445 5831 6247 6599 6810

When I graph them, I would like for the distance on the x-axis to be
proportional to the distance between the x-axis values (for instance, there
would be 240 units of space between points 1 and 2 and 1160 units of space
between points 2 and 3). But the points are coming out at the same intervals
on the graph, with the x-axis labels showing the appropriate value. How can
I get these points to reflect the difference in the x-axis values
graphically? Thanks.
