Instructions

For each graph, follow the instructions step by step. Include your command under each step. 
If you get stuck, explore the drop-down menu and copy-paste commands into your .do file. 
The Stata help files are also useful. Include the final graph in the MarkDoc document. 
Turn in the docx or pdf you create using MarkDoc. 

See the first graph (Histogram) for an example

/***
##HISTOGRAM

***/

/***
Create a histogram of systolic blood pressure (bpsystol)
***/
histogram bpsystol

/***
Plot frequency instead of density
***/
histogram bpsystol, frequency

/***
Overlay a normal distribution
***/
histogram bpsystol, frequency normal

/***
Change the number of bins to 15
***/
histogram bpsystol, frequency normal bin(15)


/***
Change the scheme too (s1mono)
***/
histogram bpsystol, frequency normal bin(15) scheme(s1mono)

/***
##BAR CHART [+10]
***/


/***
Create a bar plot (bar chart) of heart attack
***/


/***
Create and assign a label for (heartatk)
0 = no heart attack
1= heart attack
and re-run your bar plot 
***/ 


/***
Now plot mean heart attack over sex
***/



/***
Add diabetes to your plot
(mean heart attack and diabetes over sex)
***/


/***
Add a clearly-worded legend      
_hint: legend( label(1 "xyz") label(2 "xyz") )_
***/


/***
Add an informative title and a note with the data source     
_hint: note("Source: NHANES")_
***/

	
/***
Produce the same figure, but only for people 70 years old and older    
add a subtitle describing the sub-population 
***/


	
/***change the color of the heart attack bar to black and the color of the diabetes bar to gray
_hint: bar(1, color(black)) bar(2, color(gray)) _
***/	


/***Change the graph region color from light blue to white ***/

/***
##SCATTER PLOT [+10] 

***/

/***
Create a scatter plot of systolic blood pressure and age
***/


/***
Change the point size to very tiny and the color to gray
***/


/***
Add a black dashed linear fit line
***/


/***
Change the line width to thick
***/


/***
Turn off the legend
***/	

	
/***
Add a y-axis title (Systolic blood pressure)
***/
		
	
/***
Change the scheme to (s1color)
***/	
						
		
/***
Display the final plot in your MarkDoc document
***/




/***
##YOUR CHOICE [+15]
Visualize 2 or 3 variables in the dataset in a single plot. Use any type of plot. Add clear labels
to make it easy for the reader to understand your plot. Add a title and a note with the data source. 
Consider using a scheme or change the colors from the default (S2mono). 
Include the code and the plot in your MarkDoc document
