How can I make a SAS dataset read only within a SAS program? -


how can set sas data table (sas7bdat) read-only within sas program? — table must remain readonly between sessions, if user registers library , attempts write dataset. once these tables have been created not wish ever edit them - "point-in-time" reference tables others , myself may rely on. being able lock dow tables , guarantee tables have not been accidentally changed save lot of data verification each time these tables used.

i wish protect dangerous code may accidentally alter table, such :

proc sort      data = justin.myreadonlytable;              ref         start_date; run;

i not mind if can alter read-only flag in filesystem default behaviour in sas error when attempt write table occurs.

if want prevent people accidentally writing dataset, want assign alter password.

data test(alter="def");  set sashelp.class; run;

that prevents altering (writing to, replacing, deleting) dataset without supplying password in same fashion (or typing password in popup window).

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
