Add the DISCRETEX option to the HEATMAP statement:

title "Injury Frequency by Year and Month";

proc sgplot data=sample;
heatmap
  x=year y=MonthName /
  colorresponse=COUNT
  discretex
;
by InjuryType;
xaxis label="Year" values=(2020 2021 2022 2023 2024);
/* Character Y-axis preserves names; order guaranteed by sorting */
yaxis label="Month of Year" discreteorder=data;
run;

Worked like a charm! Thank you so much 🙂

An alternative way is using HEATMAPPARM statement:

proc sgplot data=sample;
heatmapparm x=year y=MonthName colorresponse=COUNT ;

by InjuryType;

xaxis label="Year";

/* Character Y-axis preserves names; order guaranteed by sorting */
yaxis label="Month of Year" discreteorder=data;

title "Injury Frequency by Year and Month";
run;
