Say that we use the **hsb2 **data file for the examples shown here.

use http://www.ats.ucla.edu/stat/stata/notes/hsb2, clear

and say that you wanted to see the scatterplot and regression line between **write
**and **read**. In Stata version 7 you might have done something
like this.

regress write read predict yhat graph write yhat read, twoway symbol(oi) connect(.l) jitter(2) sort

And you would get a graph that looks something like this.

But if you execute the graph command in Stata version 8 or later you get this error message.

writegraph_g.new yhat read, twoway symbol(oi) connect(.l) jitter(2) sort: class member function not found write is not a valid graph subcommand r(198);

You get this error message because the syntax of the **graph** command has
been completely revised (and substantially enhanced) since version 8 and the syntax
that you would have used in version 7 is not compatible with the current syntax.

There are two ways that you can deal with this. You can instruct Stata to run the command as though you were using Stata version 7 (instead of a later version) or you can convert the command to use the newer syntax. We discuss both below.

## Using Stata 7 graphic commands in Stata 8

With a little bit of extra effort you can get Stata to run
commands in the same way that they ran in Stata 7. With respect
to **graph **commands, there are 3 strategies you could choose. The
first is that you could use the **graph7 **command (abbreviation **gr7 **) as shown below.

graph7 write yhat read, twoway symbol(oi) connect(.l) jitter(2) sort

and this produces a graph that looks just like you were using Stata version
7. Another trick is to use the **version** command to instruct Stata
to run the graph command as though you were using version 7, as shown below.

version 7: graph write yhat read, twoway symbol(oi) connect(.l) jitter(2) sort

and again this produces a graph that looks just like you were using Stata
version 7. If you are going to run a series of **graph **commands,
you can issue a **version 7 **command on its own line and then all
subsequent commands (graph commands and other types of commands) run as though
they were from Stata version 7. This continues until you quit Stata or
issue another **version **command on its own line. This is
illustrated below.

version 7 graph write yhat read, twoway symbol(oi) connect(.l) jitter(2) sort graph write graph read version 8 /* or 9 or 10 */

The strategy you choose will depend on the situation. These strategies work the same way in the Stata command window or in a Stata .do file.

## Coverting Stata 7 graphics commands to the newer Stata syntax

You may want to just go ahead and convert your Stata 7 graphics commands to get the presentation quality graphs of the newer versions of Stata.

It is not possible to cover all of the different ways in which the current Stata graphics commands
differ from the Stata 7 commands.
The current Stata **graph** command includes six different graph types:

graph twowayscatterplots, line plots, etc.graph matrixscatterplot matricesgraph barbar chartsgraph dotdot chartsgraph boxbox and whisker plotsgraph piepie charts

The **graph twoway** type includes the following graphs among others:

Thus, a scatterplot can be done three different ways:

graph twoway scatter write read twoway scatter write read scatter write read

However, if you want to combine several **twoway** graphs in one plot, you will need to include
the **twoway** type declaration. The following are examples of ways that you
can produce the scatterplot and regression line that we tried in Stata 7
above.

graph twoway (scatter write read, jitter(2)) (lfit write read, sort ) twoway (scatter write read, jitter(2)) (lfit write read, sort ) graph twoway scatter write read, jitter(2) || lfit write read, sort twoway scatter write read, jitter(2) || lfit write read, sort

All of these constructions produce a graph that looks like this.

Note this will not work:

(scatter write read) (lfit write read)

Note: The separate plots indicated by enclosing the specific command in parentheses “()” or by separating the commands with two vertical bars “||”.

## Problems converting symbol and connect options

Many Stata 7 twoway plots fail in the current version of Stata because Stata changed the way the **symbol** and
**connect** options are implemented. In Stata 7 a scatter plot that includes two connected lines
would be written like this:

graph write yhat read, twoway symbol(oi) connect(.l) jitter(2) sort

Note that, in both, **symbol** and **connect** the list of indicators is given without spaces.
In newer versions of Stata you need to include a space between each of the items in the list. Further, you should
change the option **symbol** to **msymbol** (for marker symbol). The equivalent Stata 8 or later
command will look like this:

scatter write yhat read, msymbol(o i) connect(. l) jitter(2) sort

The above comments cover only a few of the many ways in which the current version of Stata graphics differ from the Stata 7 version. It is well worth you time to sit down and read the Stata Online Graphics Manual.
