In the circuit using the PIC $877$A$,$ the sensor output is connected to the DAC. The digital sensor output, converted to analog, is connected to the PIC$$s A port, allowing the sensor$$s analog output to be monitored as a graph. While graph libraries are readily available in Arduino, how can we plot a graph using the PIC?

Library used: #include

Max DAC Output Voltage: $15$V

Min DAC Output Voltage: $11\mathrm{.}8$V

What is the function to plot graph the analog output on the GLCD$?($CCS Compiler$)$
