I have some data as follows (first and second columns) in the file
mydata.d that I want to graph:
8 98826 year 2008 9 104925 year 2009 10 140153 year 2010 11 178414 year 2011
As we have big numbers in the second numbers, I have used the macro
sarith. Here's my metapost code for the plot:
input graph input sarith beginfig(1); draw begingraph(8cm,5cm); setrange(8,whatever,12,whatever); gdraw "mydata.d" withpen pencircle scaled 1.5pt;; gdraw "mydata.d" plot btex $\bullet$ etex; autogrid(otick.bot,); gdotlabel.lrt(btex $98\;826$ etex, 8,"98826"); gdotlabel.lrt(btex $104\;925$ etex, 9,"104925"); gdotlabel.lrt(btex $140\;153$ etex, 10,"140153"); gdotlabel.lrt(btex $178\;414$ etex, 11,"178414"); endgraph; endfig; end
So I am plotting the first two columns, taking away the y-axis tickmarks and labels and also writing the y-value at each coordinate in the plot. I have the following questions:
I wanted to show the year i.e. 2008 to 2010 but metapost just shows 2010 along the x-axis and this is why I have chosen the numbers 8 to 10 instead. Why is that?
If you plot the curve, you would see two dots at each coordinate where the corresponding y-value is written. Why is this happening? This occurs even if I take away the line gdraw
mydata.d" plot btex $\bullet$ etex. In the
gdotlabellines, I have to include the numbers in the second column in quotes e.g. "98826". Is this causing a problem for metapost to be accurate at such a large numbers and hence the appearance of two dots?
If from 1 we can show the year 2008, 2009, 2010 and 2011 well, then how can we display them but rotated say 90 degree anticlockwise so that the labels do not take too much space horizontally?
If I ask metapost to display the y values on the y-axis, well it will write in exponential form instead of pure decimal form like 100000, 150000 etc. How to achieve this?
I understand that metapost ignores columns other than the two columns and this is useful to write comments pertaining to that line e.g. year 2008 on the first line. However if I would like to add a global comment to the whole file such as "Number of apples I ate in each year", then I cannot do this in the beginning of the file. I presume that we can do it at the end of the file, but how? I have tried leaving blank spaces and starting the comment line with a % sign but this doesn't work.
I am using TeXLive 2010 under Win XP with MetaPost, version 1.211. I also tried TL 2011 with MetaPost 1.504.
Thanks a lot for your kind help...
