Time series using Proc sgplot

[ Edited ]

Hello,

I am trying to create timeseries graph using proc sgplot but in my case there are multiple records available for single date.this causes following graph to be formed.Here i have two rows for 21 jan .2016-08-03 13_58_56-Project - SAS Enterprise Guide.png

instead i would like to make graph like this:

2016-08-03 13_57_58-Microsoft Excel - SAS Export Jan Mar 2016 and Calculations.png

Is there any way to get 2nd graph?

 

I am using this code:

 

proc sgplot data=work.limits;
series x=time_stamp y=test_value/markers ;
refline &bin_lsl/axis=Y label= 'LSL&bin_lsl.' lineattrs=(color ='green' thickness=2 pattern =dashdashdot);
refline &bin_usl/axis=Y label= 'USL&bin_usl.' lineattrs=(color ='green' thickness=2 pattern =dashdashdot);
xaxis discreteorder=data fitpolicy=rotate display=all;
yaxis grid max=&bin_usl min = &bin_lsl ;

Re: Time series using Proc sgplot

You need to sort the data by the X variable.  There is not a unique way to plot data that has duplicate X values, but in your example you are plotting the high value before the low values, so run the following before you call PROC SGPLOT:

 

proc sort data=work.limits;
   by time_stamp test_value;
run;

Remove duplicate records before doing the graph?
