Hi all,
I have a cross-sectional data of around 1350 firms in an industry over a
period of 10 years. Each firm occurs in the data only once (when it enters
the data and hence the c/snal nature of the data). The c/snal data comprises
various firm characteristics. The industry characteristics also change over
the period of data. I wanted to draw a simple overlaid graph with time as
the X-axis and various industry characteristics such as installed capacity,
industry sales, and number of firms.
The problem is that industry characteristics have different units of
measurement. Hence, in an overlaid graph the number of firms in each year
becomes almost flat.
Is there a way of drawing an overlaid graph by maintaining different Y axes
for each line graph?
