I have all ready created bar graph based on each <tr><td></td></tr>, that is each value will be shown in each tr.
Now, I want to create a graph which will show me the value in one tr, that is in one <tr><td>$val1</td><td>$val2</td></tr>.
Remember, I will show it by an image and by giving the %$valx in the height property of the image. <image width='4%' height='$val1'>.
But it does not solve the problem. Help.
