I am plotting a line graph of the level of animal dose response (y-axis) over
time of sampling (x-axis) that is as listed on my spreadsheet. Unfortunately
the time of sampling is not at an equal interval value (-14, -7, 0, 0.25, 4,
10, 28 etc.). Currently all the time points are defaulting to spread by same
scaled interval on the graph regardless of the x value. In another word, I
want the spread of points on my graph between -14 to -7 to be much greater
than the interval between 0 and 0.25. Does anyone know how I can make the
x-axis to be plotted to scale? Thanks.
